    @ Aigeezer

    I checked out the link but there's only one monitoring station running.
    The equivalent is the Eurdep map here. How accurate and uncontrolled it is is anyone's guess..

    • aigeezer aigeezer

      Yes, I've sometimes seen three (radiation network) stations live from Europe but that's about it so far. Sometimes I'm the only radiation network station online in Canada (the second largest country in the world, after Russia) and at most we still only have a handful. We need many more stations globally, but every new one helps a bit. I imagine the various networks will merge or share data more in the long run. Meanwhile…

    Sunshine Coast,
    12th, November, 2012,

    A strong southerly came through around 12 pm on the 10th. The background average here dropped by 31% by the 11th, compared to high of 39% above for the 9th. Again this shows our local background increases with the presents Northern Tropical winds. (See Chart)

    Wet Rain Swipe, 12 November 2012,6.30 PM. Northamptonshire, UK.

    I swiped the garden table outside Monday evening after it had stopped raining.
    I kept the Soeks next to the sample (no direct contact) and I got peaks up 0.22 uSv/hr.

    There was very little fluctuation and normally the levels in the house are up and down with radon all the time but this was sustained on 0.20 for a good while. I had a few peaks up higher but I missed some πŸ™

    I let it run from 6.35 until 7.30 with very little change. I think we went out so I had to leave the sample, but I was watching it over the hour it ran.
    I don't think it was Pb 214 Lead going into Bismuth 214, but it could well of been other radon daughters further down the chain, I don't know.

  • Here in Vancouver I have had my Soeks for nearly a year and so far still getting basic average .11 microseiverts per hour, lows of .06 and highs of .13 with occasional .2something spikes.
    Pretty consistent really in a low radon area of Canada. Similar results for the last 11 and a half months.

    18th, November, 2012

    In the last 24 hours, local background levels have risen to 49% above the 4 year average of 0.10 uSv/hr. It is suggested that during these elevated background radiation events, if it rains, you keep children and pets out of the rain, plus re-divert rain tank inflows.

    See November day average chart.

    To keep up to date on local background radiation levels, regularly look at day chart, at the monitoring site.

    Testing is showing a significant amount of Radon washout during the rain events that coincide with elevated background.

    Report from the Nimbin monitoring station in the last 24 hours.

    "Took a swab from the windscreen half an hour ago after many showers, and measured more than 650cpm(SBT10) throughout the first 10 mins."

    See rain swab test chart showing significant Radon decay daughter isotopes captured from the edge of a storm, here at Caloundra on the evening of the 17th.

    This swab will be further tested to see if any long life isotopes are present.

    • vital1 vital1

      Here is an alternative rain test swab test result using the new free Theremino MCA software for comparison. Theremino MCA allows the capture of charts as they change over time. The lower chart in the Theremino screen capture is after the first 15 minutes of swab testing, and the higher chart is after 9hrs. The PRA chart in the post above is also after 9 hours.

      • Why such a short half life, I dont understand

        • vital1 vital1

          "Why such a short half life, I don't understand"

          Radon has a half life of 3.82 days, its decay daughters Lead Pb-214 and Bismuth Bi-214 have half lives that are measured in minutes. They are the peaks showing up in the rain test swab chart above.

          There maybe more longer life isotopes captured in this test swab, so it will be retested in a few days. By then most of the Radon daughters will have decayed to Lead Pb-210, which has a half life of 22 years.

          After the Radon daughter activity has died down it is much easier to detect other longer life isotopes, that may have been captured in the test swab, in very small amounts.

    • Thanks again vital1.

      Stats are where it at.

      Even if it appears like radon decay, isn't that much radon at one time a 'bad' thing? I would think so. (?) Also, aren't there other isotopes with similar decay rates?

          • Maggie123

            So – the Fukushima data is from a 'single' event, the US map represents "over time" or "from one large test" or ??. I'm not sure I know what to make of the comparison, given different source events. ?? (But I agree – the maps are interesting!)

            • vital1 vital1

              The Japanese map is for doses of I-131 up to the 24th March 2011, the beginning of the Fukushima nuclear disaster.

              The USA dose map is for what appears to be multiple nuclear tests in the USA, over a longer period of time.

              There is also a difference in the scaling between the two maps.

              In any case, both populations got a big dose of radioactive iodine I-131, at the time of these events.

              My interpretation.

              • Maggie123

                Thanks Vital1 – US dispersal map different from what I've imagined all these years in that it's not an uninterrupted flow – there are distinct and very large gaps. Also, contamination is much greater throughout central and northern prairies than I'd have expected to see, and then it 'heads back west' – Montana is shocking!

                I don't know how relevant it is but I spent my entire childhood in a solid 'red' central prairie region; and for 5 yrs as teen (summers) I worked in a general hospital in same region. All patients were from immediate and surrounding area. Most lived modest lives, didn't travel a lot – would have been continually 'exposed'. Although we did have cancer patients, it was not particularly common. There was no "How come all these cancers?" question, not even close. — Like I say, I don't know what my anecdotal info brings to the conversation, but thought I'd mention it.

              • I agree. I saw the early date on the Fuku map. I am certain it would look different now.

                I grew up in a US red zone in the sixties. Suburb of the big city St. Louis.

                I think it's difficult if not impossible at times to tell what illnesses are caused or are made worse by the exposure to radioactive contamination. Therein lies part of the problem in exposing the Nuclear Industry for what it is.

                • Maggie123

                  ChasAha – Agreed. "because for complex systems: there is no root cause. .. isn’t ..intuitive, … goes against our nature…We like to simplify complex problems so we can work on them in a reductionist fashion. We want there to be a single root cause…, because if we can identify that, we’ve identified (what) we need to fix. Fix that … and (problem solved) , right?"

                  Interesting article well outside issues of cause of disease but applies to all complex systems. It was among first 'hits' when I just now looked for something on 'finding causes in complex systems'. Same problem is why scientists irritated a bunch of people by refusing to say yea/nay if climate warming 'caused' Sandy's power.

                  What the computer engineer says in the quote is true for all of us, we're inclined to use reductionist thinking to explain situations that are wildly complex in dynamic interactive forces. BUT elsewhere I've come across scientists talking about this – and saying what I think is obvious to all of us – re climate change, nuke health risks, etc .. patterns over time so powerfully implicate X as KEY among causes, that X *must* be considered as something to tackle to restore balanced, healthy, system.

                  Problem – remove, replace, alter X and what else gets changed? But – since nukes were introduced, not there before, seems a no-brainer to abolish them! Chernobyl surely confirmed patterns!!

  • norbu norbu

    Got a high reading on the inspector today – 1,245 cpm. Wow. sierra Nevada foothills. 7 pm indoors.

  • norbu norbu

    we might leave the area, while it,s raining. A little scary.

  • norbu norbu

    yes we are a little scared of the outdoors write now. going to the desert as soon as it quits raining. Thank you for the advice. It is hot [the rain] write now.

  • norbu norbu

    The rain has stopped for now, real hard all night. I am still getting high #'s inside house. Not as high as last night, but over alert level.

    • Mack Mack

      Just as a reminder, "anti-proton" found cesium in the rain, so it's not just radon in the rain…and it's not just cesium coming down in the rain, either.

    • Norbu, I'm curious as to your location. I'm in northern California, at app. 39N, 123W, elev 1300 ft. I am getting a low background count, about 10 cpm indoors, slightly higher outside. It has also been raining here. The count is actually lower than usual, which runs about 30 cpm most of the time.

      • norbu norbu

        Hi chargedbarticle, We are near Nevada city, 2,424 elevation. I have a Inspector, got it new in August 2012. Normally it is 36 cpm average indoors. We are getting spikes of 140 cpm everyday. From August the spikes have increased. I did a swipe off the roof during the rain and with a 10 minute run I got a average of 127.05 cpm with a max of 285 cpm, there were 1,265 counts on 11/17. The 1,245 cpm spike was indoors at 7pm on 11/17. What type of counter do you have? Thanks for your interest and info. n

        • Norbu, I have a RDX DX-1 with an analog display. I'm about a 3 hour drive from Nevada City, but a thousand ft or so lower down. When you refer to "spikes" I infer you're talking about periods of short duration. How long do they last? I would not be able to detect spikes unless I happened to have the meter turned on when they happen. A count of 1265 cpm would mean the space is uninhabitable if it lasts for any length of time. Is your meter connected to some type of automatic monitor??


  • norbu norbu

    Hi chargedbarticle, yes short duration spikes, not sure how long it was. Our meter is running all the time. I have observer software, meter is hooked to my laptop, I keep all info on my hard drive. I am seeing levels over 100 cpm, sometimes 10 times in 10 minutes. thanks n

  • norbu norbu

    The one time I was not recording it happened, the 1,245 cpm spike, probably not more than a few seconds, not sure, walked in room and started acquisition and it jumped right up. n

  • In that case, I guess you could be seeing solar rad bursts, specially at that elevation. I wouldn't be concerned unless the bursts last for minutes at a time. Might be worthwhile to invest in a simple dosimeter. This would tell us how much accumulation we're getting. Another method is to monitor air filters.

  • norbu norbu

    Yes it is possible, solar rad bursts, the flares have been off the charts lately. I will order dosimeter tomorrow. Thanks for info. Will keep you posted. N

      There's been a ridiculous amount of, what I guess is, Radon progeny in almost every rain shower here in NE NSW Australia for a while now. See this CPM/Minute chart here of a sample decaying. This is the data I collected with a SBT-10 Geiger counter from a swab taken off the rear window of my car after almost a whole day of rain. "normal" background is usually around 80-110CPM with this type of GM tube.
      The rain ain't what it used to be!

  • It's All Lies It's All Lies

    A fellow chap in the UK reported did a rain swipe test over the weekend and reported 34x his normal background:

    He knows his stuff and he can tell between background radiation and the the real thing.

    I didn't get the rain he had but it's been raining today and I'll do my own wet swipe and see what's going on further north.

    We can both concur it's been quiet recently so this was a surprise.

    He did a write up but it's not on the youtube video. If anyone wants the write up I'll be happy to post it onto here.

    Went outside, with Geiger Counter, while it is raining 11/20/12.. stable at between .o8 to .10 msv/hr.

    This is Santa Rosa California area…

    Did not do swipe test.

  • Thanx for all your testing, keep it coming!
    No geigercounter here – but I've observed stuff as a cleaner… At a printing press we have 8 large air scoops that evacuate the ink from the hall in a few seconds (hall=300ftΓ—20ftΓ—3 stories). I've noticed the ink is particlizing and practically bonding with the windows underneath the scoop inflows, over the last year.
    The hedge I've cut for 6 years is dividing into useless saplings or 2inch growth over 60hrs! Like it's been mineralised with potash & poisoned at the same time.
    Mould on window wiped off yellow , not green…

    • It's All Lies It's All Lies

      I'll keep trying to post readings as regularly as I can on here! Once I get a Geiger upgrade I should be able to have a clearer idea of what I'm picking up..

      Good observations I must say! It's great you noticed the changes as most people would not even look beneath their noses.

      I'm not sure what to say about the ink, but plants and things withering away seems to be a common problem on here, Fukushima Diary and other sites. With it happening so much and images that look radiation damage, I believe it's related..

      The mould colour sounds very strange!

      The metallic taste was mentioned on the other forum for Fuki related problems:

      From what I can remember it was something to do with the radiation damaging the body and the taste is from whatever the body releases because of it.

      It could be Fuki or Sizewell, but there's no way of telling πŸ™

      Keep posting with your observations and put some dates in too! Maybe I can try and figure out where it might come from! πŸ˜€

    Monthly 2012 (Jan was highest, but on an increase trend)

    I also liked the RADON Information from here:

    Radon Increase Theory 1 or 2? Either way…
    "Any increase in background radiation levels, or Radon levels is not good. Radon is the second biggest cause of lung cancer, after smoking."

    • vital1 vital1


      Average background increases can mean you are cumulatively getting a far bigger radiation dose, than from a short term peak detection. We need monitoring stations that provide day, month, and year average background level information, as well as peak detections.

      Here in Australia, at my location, average background levels are increasing
      compared to the 4 year recorded average. As we come into summer, more Northern Hemisphere air, breaks through the equatorial barrier into the Southern air flows.

      The background level increases are significant, and can be clearly seen from
      analysis of the long term data. There are lots of coloured coded charts at this monitoring site that make it clear what is happening over time at our location.

      You really need long term data recording and analysis, to clearly determine what is happening in any location. Monitoring station spot peak observations and alerts are helpful, but not good enough to fully understand what is happening.

      Here is a page with information on setting up charting for long term recorded data analysis for those who have a Geiger counter, and are Interested.

        • vital1 vital1

          "I wonder what 'stage' level we would be considered at now?"

          At my location in the Southern Hemisphere 1 to 5 probably stage 1 at present.

          Traditionally here, we have had a much lower background average than the USA. This means we can detect much smaller changes compared to a location with higher background. Even with our present higher detections it is still lower than the Australian (0.17 uSv/hr) and USA (0.34 uSv/hr) average. The Japanese average was 0.081 uSv/hr before Fukushima. Background levels could have been much lower everywhere before the advent of the nuclear age.

          Because we have 4 years of historical recorded data to compare with, before 3/11, it makes it clearer to see that background levels here are increasing.

          The Northern hemisphere dynamic is probably a lot different. There must be people in the Northern hemisphere who have long term data that could shed light on what is happening there.

  • kunzen

    Sydney is now around 0.17mcSv/h.

    • vital1 vital1

      The Inspector Alert Geiger Counter used in this video is more sensitive than the average Geiger Counter.

      There is the possibility that the Inspector Geiger Counter is showing a
      higher than background radiation detection, because of a higher Potassium K-40 content in the coffee beans.

      A very small amount of radioactive Potassium K-40 is in all living things, as part of a natural salt Potassium Chloride. Some foods have a higher Potassium chloride content than others, and dehydration will concentrate this.

      The only way to know what is causing this higher detection for sure is to test it with better equipment, to determine if it is a higher K40 content, or another radioactive isotope contamination is present.

      We have been through this process here, with foods like English Brewers
      Yeast, Cocoa Powder, and some other dried powdered foods, that have high K40
      content. People here using sensitive Geiger counters, or Inspector EXP Geiger Counters, to test these foods where getting much higher that normal background detections.

      On testing these suspect items with better equipment we concluded that these
      food items had above average Potassium Chloride content.

      Dehydrated and powdered foods with high K40 content can cause false positive detections, with sensitive Geiger Counters like the Inspectors. The only way to know if this is a false positive detection or not, is to test the sample with much better equipment.

  • eatliesndie eatliesndie

    "foods with high K40 content can cause false positive detections" – This is a more than a little misleading. K40 if radioactive, natural or not. If it is above average content it should be avoided – Detecting high amounts of K40 in anything is not a false reading, but an indication of radioactivity. If your Geiger counter can not detect this it is not good enough and will not detect small amounts of other radioactive elements/isotopes.

    • vital1 vital1

      "K40 if radioactive, natural or not. If it is above average content it should be avoided."

      The foods I mentioned in my post examples above, are in powdered form, or dehydrated. Any salt content will be concentrated in this form. Before people consume them, they mix them back with water. It is then nowhere near as concentrated.
      A sensitive Geiger counter can detect and show this as an above background reading, in some concentrated or dehydrated foods that have a high Potassium Chloride content. I agree, it is good to have a Geiger counter that is this sensitive, because you are more likely to detect food contamination.

      The body naturally regulates the amount of salt in the body, whether it be Sodium chloride or Potassium chloride. We need Potassium Chloride, or our bodies will not function properly. There is no way to remove the radioactive Potassium K-40 from the Potassium Chloride we consume. We always have around 4,400 Becquerels of K-40 in our bodies. Our bodies have evolved to deal with it.

      K-40 is nowhere near as radioactive as the artificial isotopes like Cesium or strontium, per gram etc.

      The only way to tell for sure, what is creating the above background detection in the coffee bean in the video, is to test them with better equipment.

      • vital1 vital1

        The question is are they safe to eat?

        In this video the person is using a long count Geiger counter testing method, which is excellent. This method helps to maximize the ability of a Geiger counter to detect contamination. This free guide explains the issues of using a Geiger Counter to test food for contamination.

        If all you have is a Geiger Counter to test your food.

        If after testing you are getting an above background test on a food item.

        It would be best to avoid eating the food until it was confirmed it was safe. The only way to tell for sure, is to test the item with better equipment. This is what responsible government should be doing.

        Communities and individuals can now set up a cost effective food testing lab. This equipment is much more sensitive than a Geiger Counter. Here is a free Guide.

      • * First of all, it's absurd that we should have to be buying equipment to test our own food. That's what we're supposed to have government and pay taxes for.

        * Yes: if your Geiger counter (GC) and techniques are sensitive enough to take a shot at testing food, you'll often be reading K-40 beta. Any food and flesh which contains potassium (like our own bodies) also contains a bit of K-40. You can discern K-40 (the CPM stays the same) from Iodine-131 beta (8 day half-life) from radon daughters beta (about a 40 minute half-life). You can discern beta from alpha with a paper shield and the both of them from gamma with 1/8th inch of aluminum. But to do that work means long counts (100 minutes or more) and bringing your sample to your GC –which is in a fixed, clean, and recently background radiation calibrated location.

        * While you can detect beta at less than 130 Bq/kilogram with an "Inspector" GC that way, GC long count gamma sensitivity is over 1000 Bq/kilogram (depending on energy levels) –which is not sensitive enough to "OK" food. (It might steer you clear of gross contamination.)

        ** I'm an amateur and NOT qualified to give this advice. I only do so by the default of qualified others. Any apparent positive results should be tested further by a competent person with a gamma spectrometer (and I'm not just covering my butt). What I've gleaned since 3/11/2011 is at:


  • ALERT reported in Texas:
    7:03 PM local time, November 23rd
    Borger, TX (Panhandle)
    (which is 40 miles northeast of Amarillo)

    Reported on Radiation Network.
    Surpassing 100 CPM multiple times over a half hour period.

    from their message board:

    "…There was no rain or wind at the time, the jet stream was flowing far to the north, and no local earthquakes of significance that might release Radon, no solar flares of note (which probably wouldn't be localized, anyway), and no NRC events in the area. The operator knows of no radioactive persons or pets nearby that were undergoing medical treatment."

    The Pantex plant is located 25 miles to the southwest. For those unaware, Pantex is a division of Babcock and Wilcox, and operates a nuclear weapons assembly and disassembly facility outside Amarillo."

    Amarillo, TX always has the 'strangest', best word I could think of, readings of any city anywhere on the EPA Rad Net system's charts.

    They are also downwind of Los Alamos county, NM.
    One of the top ten richest counties in the USA.

    • I wonder how many OTHER products are made with over background powdered milk?

      For some reason powdered milk, even pre Fukushima has been known to test high.

      See potrblog milk tests:

      Q: Is it reason for concern?
      A: YES!

      Anything above background is not good for you. Especially children.

      This means we've 'most likely' been getting some dose via Milk and the products made with milk for a long time.

      It also means the EPA has failed horribly and downplayed it or lied for a very long time.

      I cannot locate the article, but I have read that Vitamin D was added to milk in the 50's to help stop the uptake of strontium which goes to bone like calcium does.

      They've never stopped adding it. I wonder why?

      Keep and eye on "The Food Lab", for the latest International reports of Radioactive contamination of food items.

      Try to keep this data base as up to date as possible. If you know of a food item contamination report that is not in the list at the site, please post a comment there.

  • vital1 vital1

    Cs-134 was detected in the Infant Powered Milk from New Zealand, that was sold in South Korea. Look at the chart results in the report to see the Cs-134 detection.

    This significant because the Cs-134 contamination could only have come from the Fukushima Nuclear disaster.

    This presents a number of possibilities.

    1. Fallout from the Fukushima Nuclear disaster has reached New Zealand.

    2. A contaminated item that originated outside of New Zealand was mixed into the milk.

    3. It was contaminated in South Korea during processing and packaging.

  • Arizonan Arizonan

    Learning how to use recently purchased Mazur-600 GM, live in Tucson, AZ, elevation 2,600. Readings inside vary from about 40-70 CPM. Readings near the rain downspouts outside spike up to 200 CPM. Putting the device within 1 cm of one gram of diced Cal-Organic produce showed only slightly above, at 72 CPM. Am just learning how to use this thing, so am not sure yet how this compares with elsewhere. I appreciate any insight.

    • aigeezer aigeezer

      Arizonan, I noticed those results while looking at your new station from the radiation network site, and I wondered what you would be discovering. I hope you keep active in chat there with whatever you find – there's some solid talent available for fine-tuning and interpretation advice, possibly leading up to detailed scintillometer testing of samples if appropriate (talk to AP).

      On another front, I saw your post yesterday about protest arrests, and that prompted me to go back over some of your old posts here. Wow, you have really been doing your part – thank you very much for what you do.

  • weeman

    8 to 20 Cpm in Toronto, never seen it above 23 Cpm. Why so low compared to USA, I would be looking in your own back yard, anybody have a explanation, unit is a mazur prm 8000.

    • aigeezer aigeezer

      weeman, the prm 8000 is not a pancake probe unit (I've got one also). It will normally read about one-third (roughly) of what the pancake units read. The new prm 9000 is a pancake probe unit.

      Tim (the radiation network guy) is working on a new version of the map software that will help deal with the apples/oranges issues from different units. For now, we just have to remember to allow for it.

  • Here in Vancouver, I did a 15 minute count with my Soeks 01M. Overall I would have to say average is higher today at .14 microSv/hr instead of the usual .11 Wish I knew what Weemans 8 to 20 cpm translates to my .11 microSv/hr, as T.O is my home town.

  • fuk u shima

    Well I live in Bali Indonesia..
    Here my indoor counts range from lowest of around 10 Cpm to waves of 40 cpm and recently a 1/2 hour of steady 55cpm.. this was on 15th November.
    Waves last a few seconds to a minute.. but may hover in the high 30s to mid 40s for 1/2 hour.. then drops off to around 15 cpm as usual BG.. occasionally will drop to 10 cpm.

    This can be anytime of day or night.. my GMC-300 detector sits on top of the fridge 24/7 and the alarm goes off at 40cpm.. usually 3 -4 times a day.

    For those who may be interested.. i read on youtube where you can use Betadine or Iodine liquid on the skin as an alternative to the hard to get and hard to find ?? iodine Tablets.

    Much easier.. safe . and does the same thing ie tops up the bodys level of iodine.
    Also one of the best Radiation scavengers for the body is Rosemary.. or if you can find it.. Rosemarinic Acid.
    Do a Google also a youtube search.

    Well good health to yoiu all.. but I f I was that guy in the Rockies with a 12oo cpm count.. I wouyld be deinitly packing up and LEAVING pronto
    That is WAY to dangerous


  • PhilipUpNorth PhilipUpNorth

    I have been concerned about the general increase in radiation levels all over the US this fall. A few minutes ago, we had 8 reporting stations on Radiation Network reporting 50 cpm or higher, all over the US.
    Background level should be about 10 cpm everywhere except Colorado, which may have a background of 20 cpm due to elevation, and the Philadelphia/New Jersey area, which may have a background of 20 cpm from Three Mile Island. Otherwise, background levels for the US should run about 10 cpm. Everything above 10 cpm, I would put right on TEPCO and Fukushima. And the readings have been going up in recent months as Fukushima fallout accumulates all over the US.

    • The Philly area is surrounded by Three Mile Island, Limerick, and Oyster Creek πŸ™ I can't wait to get a Geiger Counter… come on Santa; daddy needs a Geiger Counter πŸ˜€

    • When I first started observing Radiation Network the numbers were indeed lower.

      The average number of yellow dots over 50 was 3 or 4 last spring. That climbed a bit this summer to 5 or 6 at times.

      Now, I have seen as many as 10 locations over 50/60 cpm plus.

      This is an observation only.

      • aigeezer aigeezer

        You post that theme often, ChasAha, and when I notice I try to remind you to remember some of the other variables in play, such as: the number of stations in the network has also been increasing over the same period; you have no way of knowing what kind of GC you are seeing results for (some models read higher than others), and you have no way of knowing whether the addition of new units is statistically significant or random (geographically or technologically).

        I keep hoping to see you post your own results.

        I don't usually post mine in the thread because anyone can see and (mis)interpret them 24/7 at the radiation network site. However, for the record, my average has been 13-14 cpm since I bought my GC (a PRM-8000), every day, every week, every month so far.

        • I appreciate you listing the other variables.

          I clearly state.

          This is an observation only.

          I agree there's a lot I don't know.

          If I understand what you are saying is that; if your not a member then any observation of the Radiation Network map is useless?

          So are you saying based on your inside knowledge that there are or are not trends on the Radiation Network or is that information privy only to members? Or is the data so varied nobody can really make heads or tails out of anything that's meaningful?

          Clearly your Geiger has been regular. That's a good thing.

          • aigeezer aigeezer

            There is no general upward trend that I am aware of.

            • aigeezer aigeezer

              Here's a rough methodology that may be useful for the general public:

              Choose one or more stations to track.

              Observe whether a given station trends upwards or downwards over time (not moment by moment – that is random).

              If it does change (by some non-trivial amount), try to find out the cause.

              If instead you try to try to track overall network behavior without knowing the number, placement and/or composition of the individual components, it is… crazy-making.

    • aigeezer aigeezer

      "Background level should be about 10 cpm everywhere except Colorado". That's a surprixing claim. How do you arrive at the 10 cpm number?

      In case you don't know, different models of GC are calibrated differently. The cpm readouts are not counts of individual universally-detectable discrete events. Two different models placed side by side will typically give very different readouts.

      There is presently no way to tell from the public map what kind of counter is in use at any particular site, or what the overall mix of reporting stations is. In general, new buyers seem to opt for the pancake-probe models as they give more detailed results. Pancake-probe models happen also to give higher cpm readouts than the all-in-one (no external probe) models. If someone switched from one model to another (as I am thinking of doing), it could appear on the public map as a big unexplained jump in radiation for that station.

      My (all-in-one) model has not varied in its average result readings since I bought it last winter, if that's any reassurance.

      Is your own station's readings increasing? That would be an interesting development.

      • eatliesndie eatliesndie

        I have several different GCs all with different GM tubes. On one, 80 to 100 cpm is usual background, and on another 10 to 25cpm is usual. I have several GCs in between.
        I found it a little confusing when I first checked out Radiation network monitors because there was no obvious info about GM types or conversion rates to calculate uSv from CPM or even individual station CPM history to gauge any significant variation over time, which is quite important if anyone from the general public wishes to glean anything useful from the current real time data.

        • aigeezer aigeezer

          I agree. I think Tim (the radiation network owner) is working on ways to provide more information to the public in a future release of the map software.

          For those who "demand" more, it's worth remembering that he provides the public display as a freebie – he doesn't owe the world anything. Our governments, on the other hand….

    • "There is no general upward trend that I am aware of."
      – aigeezer

      How can so many 'independent' upward detections be occurring yet you see no trend on Radiation Network?

      I do see trends and I don't care that I don't have all of the data. I state it's an observation only. There's no harm in that.

      My observations are my observations. Accurate or not. I will continue to make them as I see fit and as others have done on this site.

      If you want to continually 'put down' my observations, for whatever reason I am sure you will.

      • aigeezer aigeezer

        "I do see trends and I don't care that I don't have all of the data"

        Do you not see the problem with that approach?

        • No, I do not see the problem.

          I have never stated that what I observe is fact.
          If you want to take it that way that's your problem.

          What part of 'I have never stated this as fact' do YOU not understand?

          If Tim doesn't want people commenting on his private 'entertainment purposes only' web site then he should remove it from public view!

          Yet, you use the 'disclaimer' "that I'm aware of". So when this trend is finally documented properly you will be able to say. "I wasn't aware of that". How convenient?

    • aigeezer aigeezer

      Thanks, that IS an interesting one, Cataclysmic. It's from the government monitoring site too (of all places).

      Do you have a sense of whether that is a trend/jump for that particular site? (I haven't been following Radnet in a while).

      The private radiation network has a station up near Spokane, reading 53 cpm at the moment. Of course, something could be ultra hot but very localized and/or a wave of some kind may have passed through.

      Keep us posted if you find out more.

      • Cataclysmic Cataclysmic

        We trend high, even prior to 3/11, but not that high, looks like it has been in the 100+ for at least 7 days..I am afraid to dig much deeper.

        • aigeezer aigeezer

          As I recall, you're a long way from the coast and Hanford is the only "obvious" source that comes to mind, but… of course… it could be whatever.

          I sure wish we could have a bunch more "ordinary people" reporting details at times like this. With just these teasers we could be chasing moonbeams or missing something huge.

          Thanks for the heads-up, Cataclysmic. I look forward to your updates (gulp).

        • probie probie

          Hi Cataclysmic, Not sure how much I can offer nor how it relates to the EPA monitors in the Spokane area, but regarding the Spokane monitor on radiationnetwork, on or about roughly 8 or 9am on 11/26, their regular average jumped from their steady normal 46-47cpm range to 59cpm. The elevation was steady until it dropped back to normal around 8am on the 28th. When I noticed the rise in average on the evening of the 26th, the jet stream was approaching with an accompanying storm from the west yet the lower bands were coming from the SE and/or SSE from the direction of Hanford (at about 7mph if I remember correctly). All surrounding stations including Hanford station (a bit south of Hanford), western stations and Montana were normal average throughout that period. There was no response from the Spokane station as to any possible changes in position of Geiger, visiting patients or neighbors or any other physical changes so I just don't know. Oftentimes a simple move from one floor to the other could cause a change if radon is an issue etc but again I just don't know. What I do think is that whatever the cause is a local one as usually the outside Seattle station will pick it up first but it too was normal.

          • probie probie

            It appears, like aigeezer pointed out that Hanford is the likely suspect and it very well could be but considering the large rise in Spokane so far away, one would think the Hanford station, just a skosh south of Hanford site itself and despite wind direction/speed, would be affected too but it was not. I will say I have seen tested known emissions pass right between stations before without detection though so who knows…sorry I couldn't be of more help but without more evidence my guess is local vs. Fukushima. Either way not a good feeling I know as radiation is radiation. Have you been watching the EPA monitor very long? Is this rise you mention a significant one vs past levels at this monitor?

    • NoNukes NoNukes

      Thanks, Cataclysmic. It is strange to read, I had a nightmare about gamma radiation last night. I "watched" the waves going through my daughter and tried to stop them. Shiver.

    1st, December, 2012

    The day local background average for the 29th of November again hit 40% above average. This was the fifth time in November that the day local background average had gone 40% above average. (See day average chart)

    This pushed the November monthly average to 31% above average, compared to the 4 year recorded average. (See monthly average chart)

    Full historical local data can be found here.

    This is showing a steady increase in background radiation levels over time, at our location in the Southern Hemisphere.

    Here is the result of a recent Radon washout tests using a scintillator. This test was done recently on the Australia east coast, after a rain event. The Radon decay daughters peaks are marked. This shows what is in Radon washout.

  • Radiation Network: (where you'll often see a dot for my station in the middle of the Oregon coast) offers its members a similar but zoom-able map display along with the all-station average. That average is somewhat compromised due to new stations coming on line plus existing stations logging on and off –but it's been remarkably steady for many months, usually indicating 29 or 30 CPM.

    Looking back over my own records (mostly 100 minute averages for the past 10 weeks), the CPMs here have run between 34.99 and 38.98. (My readings are gamma only.)


    • My sister is in Bandon, OR. I look at your dot often.

      How long have you been taking readings and would you have data from 1 year ago to compare to?

      I also tend to forget that some detectors are Gamma only.

          I remember seeing your site way back when. I recognized the photos of your setup. I thought the concentrator was a good idea.

          Great notes! I couldn't read them all, but that's okay.

          It did seem like a from the 10th to the 21st of September 2011 something was going on. I couldn't really read the notes, so maybe you were doing something else. Still it did not go above 100. So that's good.

    When doing a query on the EPA RadNet for Pierre, South Dakota Ive been seeing some really high beta counts for awhile now. An example is on: 11-29-12 772 beta. I'm sorry I'm not sure how to link it in here. I've wondered what the difference is in the RadNet CPM's as compared to the radiationnetwork CPM's ? Is it different Geigers & tube size? I'm sorry if this is a stupid question just trying to figure this all out. I really appreciate this site & check it daily.

    • {Apologies for that false start post above –to ChasAha, which happened when I hit the tab key –I think.}

      * Those uninterpreted "gross" beta and gamma graphs/numbers that RadNet puts out are fairly useless for public information –in my (humble and unqualified) opinion –and per:


      Without knowing how/when the beta numbers are generated, without at least a basic understanding of isotopic gamma energy distributions –so that one might draw inferences from RadNet's gamma graphs (assuming they're not fudged), our watching those numbers is rather like my kitty chasing a laser light dot on the carpet.

      * All I can say is that, if ever Radiation Network's averages take a big jump, then so should RadNet's graphs.

      * Radiation Network currently updates/posts one minute averages, from which you can expect long term swings of up to +/- 18cpm –even in a rock steady field of background radiation (commonly +/- 6cpm, but up to 3 deviations from average –due to "Poisson distribution", per:


      I believe Radiation Network's public web page will eventually be going to 3 minute updates/averages –for about +/-10cpm (in the course of an afternoon, say).
