    Kauai station is 141 CPM

    There are 4 monitors up in Colorado this morning. Haven't seen that in months.

  • Wisconsin. Blackcat systems showing a day long increase.
    Not an alert level but definitely a 'bump' up.

    Not numbers displayed are in uR/hr (microRem per Hour).

    I clicked on the slightly hidden orange circle over Wisconsin.

    The graph is ongoing. (7 day window)
    It shows yesterday from 12 pm through 12 am.
    link to graph:

    At 4 pm it hit 21 uR/hr.
    The average on the graph for the week is about 10. So this is a doubling of that for about 12 hours.
    (Alert is considered 28)

    This could also correlate with yesterdays high Minnesota readings. (speculation)

    24th, October, 2012

    Well that continuing strong southerly that came through on the evening of the 22nd, caused a dramatic drop in the 24hr average local background level for the 23rd.

    The 24hr average went from 0.145 uSv/hr (45%) above the 4 year average of 0.10 uSv/hr on the 22nd, down to 8% above average on the 23rd. This 40% drop in 24 hours happened in dry conditions.

    • vital1 vital1


      Also on the morning of the 22nd between 12am and 8am, it was 48% above average. In recent months I have occasionally detected greater than average for the time period from 12 am to 8am in the morning than for the whole day.

  • Radiation Network seems to state that the ALERT Level readings in Grand Rapids were not a malfunction.

    I think they know it's not 'radon washout' too, but they have to mention it like a disclaimer.

    "…or something more sinister like man-made nuclear reactor by-products."

  • yvonne

    The fredrick WI went over 100 (103) at about 10:50 AM. I'm not hooked up to the network just happened to see it when I was checking. Also makes me wonder about local plants south or west of this area? Fort Calhoun, Monticello or something in South Dakota. The radnet shows really high lately in S.D. & Nebraska. Just wondering because it seems high at times the jet stream isn't going thru also?

  • PhilipUpNorth PhilipUpNorth

    HIGH RADIATION ALERT for Minnesota (71 cpm), including Minneapolis (62 cpm), Colorado (57 cpm), Detroit (63 cpm), Pittsburgh (57 cpm), Philadelphia (68 cpm), and Atlanta (52 cpm). Indicated right now on Radiation Network.
    Alert level is considered 100 cpm. Since the radiation levels are much higher than normal over such a wide area, I agree with those who have said that the three coriums in the rock and moderating ground water under Fukushima have experienced a criticality event in the past 1-2 weeks, that has resulted in higher than normal radition levels. Stay out of the rain, especially. My home is shut up, with the furnace blower on, and air cleaners running.

      Another Radiation Network alert report:

      Update: 10/25/12, 10:30 P.M. – Radiation Alert in Wisconsin

      A neighboring station to Grand Rapids, MN, namely Frederic, WI is experiencing the same elevated radiation levels as detected by Grand Rapids only a day or two earlier, the two stations essentially corroborating each other. At right is Frederic's graph from yesterday, showing readings at times exceeding our 100 CPM alert level. The region is experiencing a combination of rain, sleet, snow, and high humidity.

      (Either the time or date is incorrect here, since 10:30 pm on the 25th hasn't happened yet)


      POTR blog has a new video about this too:

      "Maximum Alert: Airborne Radioactive Fallout On Jet Stream Boundary"

      "We expect this system to move towards Saint Louis later today, and readily detectable levels of airborne radiation my be present! …"

  • I would expect Rad levels to go up in Pennsylvania, New York or Maine on the Radiation Network's system.

    Nothing significant so far as I've seen.

    A quick Radiation Network general observation:
    I've been looking at the RN Map for well over a year now. Initially, there were never more than 2, maybe 3, yellow dots out of the 50 locations or so that I could see that displayed a cpm level greater than >50.

    — Now however, within the last month or 2, that has jumped.

    It now averages 4 or 5 locations above 50 cpm and quite often shows 6 or 7 above the greater than 50 mark. Indicating an increase to greater than 10% of the locations showing greater than 50 cpm on a regular basis.

    I'll bet somebody out there has kept records of this and has a 30 or 60 day graph that would show us the current increase trend.

    Tim, where are you? (Radiation Network)

    London radiation registered lowest average reading at 0.142 mcSv/day yesterday due to cold arctic winds. It was the cleanest air since one day at the beginning of June this year. I am convinced, warmer winds from the South gives higher radiation readings….probably from France 🙁

    If this is an anomaly I'd be so glad!

    (29 October 03:30)

    BUT there was a HUGE spike on a monitor on Eurdep, and it's directly next to the good old Fessenheim plant which had a fire last year. Funnily enough there was a huge spike at the same time..

    It was 28,000,000,000 nanosieverts/ hour.

    In microsiverts that's: 28,000,000 uSv/hr.

    Not good news!


    Wow! The radiation levels are climbing on the East Coast (mainly PA) thanks to hurricane Sandy. Current readings on the radiation network have PA at 81. Michigan is kind of high too at 74….

    Sunshine Coast,

    October Monthly report

    The local background radiation average for the month of October was elevated at 19% above the four year recorded average. It was also a very volatile month, with dynamic swings in local background radiation levels. These dynamic swings in background levels were tied to wind direction. Northerly wind direction consistently increased local background levels of radiation.

    At the beginning of the year, we had lots of short duration spikes in radiation, that were detected up the eastern sea board of Australia and in New Zealand by independent testers. Now we are seeing broader increases over longer periods of time. Click the link to see the October day average chart, to see this dynamic.

    After doing a lot of rain swab scintillator tests, what was detected were increased radioactive Radon gas levels. Here is a link to information on Radon gas.

    • vital1 vital1


      The local rain washout test chart, link below, shows Radon, the daughter decay chain of Lead, Pb-210 and Pb-214, plus Bismuth Bi-214. Longer period testing showed that all that was left after leaving the test sample for a week, was the long life Radon daughter Pb-210.

      There are a number of theories that have been put forward for the increasing Radon levels.

      Radon Theory One

      50 times more Uranium than normal was detected in air over Hawaii on the 21.03.2011. (

      All this extra Uranium that has been aerosolized into the air from the Fukushima Nuclear Disaster into the Northern Hemisphere atmosphere, is constantly releasing extra Radon gas. This would explain the increase in radioactive Radon gas coming across the equatorial boundary from the Northern hemisphere.

      • vital1 vital1


        Also, there are constant steam releases from the underground super heated melted Nuclear reactor cores, hitting ground water. This releases a lot of extra Radon that is in the cores and soil at Fukushima. Watch this video from the 30.10.2012 to see a live shot of ground venting at the Fukushima site, from the underground Nuclear reactor cores. This is a common occurrence there. (Thanks to enenews member nuckelchen, for this video.)

        Radon has a half life of 3.82 days so it is around for at lease 38 days. You multiply the half life of an isotope by 10 to get the effective life of it in the environment. If a sufficiently large enough extra amount of Radon is continually being produced in the Northern Hemisphere atmosphere, there is plenty of time for it to get here, and be detected, if the weather conditions are favourable.

        Radon Theory Two

        Increasing Radon levels have nothing to do with Fukushima, but by increased global temperatures, or seismic activity in the Northern Hemisphere.

        Any increase in background radiation levels, or Radon levels is not good. Radon is the second biggest cause of lung cancer, after smoking.

        • +1

          So really, if I hear what your saying correctly is that…

          Yes, sometimes there's radon. Which we know is 'sometimes' naturally occurring. But, what we are detecting now is MORE than normal, which in turn would be a 'bad' thing.

          So when the experts say, 'it's just radon'. They are not telling the 'whole' truth for some reason? 🙁

          • vital1 vital1



            More testing needs to be done as the dynamic seems to be changing. We have had lots of discussions here about this. "Theory One" above is what seems to make the most sense from the test results. It is just a theory. The testing station is about mid way down the East Coast of Australia.

            The Northern Hemisphere fallout dynamic could be a lot different, with lots of other isotopes present in the rain, or snow washouts.

            • NoNukes NoNukes

              vital1, thank you for your theories. I have been meaning to ask you all what you think of Radiation Network's theory about plastic bags causing artificially high readings, trapping radon? Update: 8/12/12, 7:25 A.M. – Breaking News! – Fukushima triggers run on Plastic Bags 🙂

              Yesterday, a monitoring station in Indiana broadcast an Alert over the Radiation Network, momentarily exceeding 100 CPM. Although set up indoors at the time, stormy weather seemed to be the culprit, until the station operator offhandedly mentioned that his Inspector Geiger Counter was safely inside a plastic bag. As soon as he removed the detector from the bag, voila!, the readings dropped immediately, as shown on the graph.

              I have seen this phenomena many times since Fukushima, where placing the Geiger counter inside a plastic bag causes an over "accumulation" of radiation counts. I don't know why this happens. My personal theory (although not a very good one) is that radon gas has a chance to build up in the unventilated space of a bag, in the same way that radiation readings are often elevated in a radon infested, sealed basement.


              • vital1 vital1

                Interestingly, the rain test swabs here are placed in a zip locked plastic bag to protect the scintillator tube from wet sample contamination. The scintillator here is a Gamma scintillator so it can't detect Alpha radiation.

                We have left those samples in the same bag for days and retested the samples. No increase in Radon daughter isotopes were detected except for Lead isotope PB-210, which is the long life Radon daughter isotope left over from Radon decay.

                Pb-210 puts out a Gamma at 47 keV. The very tiny amount of Pb-210 we are taking about here is so small, you would be hard pressed to detect it with a Geiger Counter.

                The only reason to put a Geiger Counter in a plastic bag would be when testing out in the environment when it is raining,or snowing. Water and electronics don't mix well.

                Also if you are placing it on a dusty or wet surface that could be contaminated use a spacer or plastic bag to protect the Geiger from contamination. Once you place it in the plastic bag you prevent the Geiger from detecting Alpha radiation, so a spacer would be best if you are trying to test for Alpha isotopes.

                You should not be keep the Geiger counter in the plastic bag for any length of time.

                Read the free Geiger Use guide.


  • It's All Lies It's All Lies

    I'm from the UK and I get peaks up to 0.22 in the house. Funnily enough the bedroom upstairs is the hottest place in the house..
    When I was in Devon the readings were lower. I did a rain swipe last week and it stayed on 0.21 constantly with no flwhat uation. I'm part of a radiation watch group and one very good chap said a tell tale side of radon was fluctuations in my Soeks. The swipe had none and stayed over 0.20 for a good half hour. Hard to tell what the half life or isotope was but I did wonder.

  • "I am suspect of the integrity of the radiation networks readings. As of late when readings get close to alarm levels it suddenly drops or disappears." – user timemachine2020 November 3, 2012 at 11:46 pm

    I would have to agree on the Radiation Network unfortunate 'lack of' integrity aspect.

    There have been many reports and screen shots of ALERTS that never get responded too. The ones that do get a 'blip' on their message board are usually 'put off' to malfunctions or the use of plastic baggies. It usually takes them 48 hours or more to put something on their message board if it appears.

    Has there ever been what they (RN) would consider a real alert?

    The readings are basically 'live', but when something goes 'hot' there is not a reasonable response time. Time and distance are critical when radiation exposure is involved. So, for other than after the fact 'entertainment purposes', I would not rely on it.
    (just my opinion)

    They have given no analysis, from what I can see, as to any trends.
    One would think they would know and see trends and report on them.

    I have surfed there site for some time now and I have observed what I feel are trends.

    I am not a paid user of Radiation Network and I think the concept of monitoring is more than just highly needed.

    It is my sincere hope they can do better job soon.
    Who knows, maybe they will read this?

    • aigeezer aigeezer

      That is very irritating, ChasAha. There are always hit-and-run mischief posters here, but you've been posting FUD about the radiation network for a long time. A solution to your problem is:

      1. Learn something about random fluctuation, sparse matrices, stochastics and the like so that you have a better chance of distinguishing trends from noise – or at least think twice before drawing conclusions from casual observations.

      2. Buy a geiger counter and learn how to use it.

      3. Connect it to the radiation network (or not, your choice).

      4. If you connnect, observe for yourself that your data is reported fairly.

      5. If you connect, converse to your heart's content with station owners when they get anomalous readings, until you satisfy yourself that there is no shadowy "they" with a "lack of integrity".

      6. If you connect, and if your GC acts up one day and gives odd readings, watch for yourself how quickly word of your "lack of integrity" spreads on the Net.

      The radiation network owes you nothing at all. It is a group of volunteers (I am one) who take the trouble to post readings they get on their personal equipment and who try to understand – in painstaking detail – what their readings mean. Start helping or stop whining, preferably both.


      • Who's the whiner?

        If you'll note I am not the only one who feels this way.

        I AM trying to help RN by giving them an honest review as an outside observer. What do I get for that honesty?

        Instead of being irritated and calling people names, perhaps you could express our opinions to those you pay a fee to for such a great service. That's what I was hoping.

        –> My observation and concern is that there ARE alerts that do not get responded to or are not addressed quickly to the general public.
        Am I wrong?

        If a business, (they charge a fee) like RN, places critical data in the public eye, regardless of any legal disclaimers, then it should be done properly.

        I think you may have taken the 'integrity' part personally and I apologize. I am not saying the individual volunteer/hero Geiger operators are lacking. I am saying however, that I would 'like' to see whoever runs the program/web site do a far better job.

        btw – I have taken Physics with specialized studies in wave movement. I understand random anomalies.

        I also think our EPA/government agencies should be on top of this too, but they are not. Gee, I hope they don't call me a whiner.

            Aigeezer and ChasAha please try to remain calm. Both of you are contributing in your own ways. The important thing here is to remember who you are doing this for.

            It would be wise to not trust any one geiger counter or any one particular radiation report site. Cheap or poorly working geiger counters are a reality in these types of situations. Radiation sites are only as good as the staff.

            Think of it this way: If you are working at one of these radiation reporting sites you are not only being monitored by regular citizens you are being monitored by the government.

            I realize I am not a paid user. But the lack of reporting and analysis from a general observer viewpoint seems lacking and is frustrating.

              Chas, while some of your points are valid, it's time to stop criticizing from the sidelines and get in the game. Acquire your own Geiger counter and join or don't join ours or other networks so that you are not dependent on me and others for _second_ hand information. To put it in the form of a rhyme, it's called created knowledge, versus related knowledge.

              Tim, President

              He states nothing about addressing my 'valid' points.

              "…stop criticizing from the sidelines and get in the game." – Tim

              This is NOT a game!
              It is NEVER time to stop criticizing!

              Especially when I receive a lame response like this one.

              If you have knowledge, of ALERTS or trends you should pass it on. Do the right thing.

              He does give one piece of good advise. Everyone should own a Geiger counter so they don't have to rely on others with arrogant attitudes. That's how I took it. 🙂

              I didn't get a 'thank you' or 'have a nice day'.

                Chas they have been caught with their pants down. They obviously are not as skilled with radiation monitoring as they claim.

                This is an important matter and for Tim to brush off a valid concern so easily means he may have another agenda. Someone had better find out who Tim really is… and who he really works for.

I don't understand how you buying a geiger will help to answer these questions about past high readings in Oregon or North Carolina, etc.? Is this a way of saying that if you pay for the membership, then you get more information about the high levels? Is that true, aigeezer, do you have more info about these than we do? Thanks for your work, aigeezer, we appreciate it! These high readings are posted with increasing frequency. If I yell fire in a crowded theater, it comes with responsibility…

                  Thanks, NoNukes. Whenever a station reading exceeds the (arbitrary) 100 CPM, a loud klaxon alert sounds on the PC of each radiation network member. Nobody has the slightest idea what the alert means at first, and everybody tries to figure it out.

                  Sometimes Tim can contact the station owner by phone or email. Other times they may not be home. They may or may not be aware that their station caused an alert. Most of the time they sheepishly say something like: battery failure; household member or neighbor just had radiation therapy; they were testing a (radioactive) lantern mantle and forgot to go offline… and so forth.

                  Sometimes nobody can figure out what caused it. Sometimes it seems to correlate with storm-induced radon. On and on.

                  Meanwhile… on the Net… people who have seen only a blip on a map irresponsibly spread fear, uncertainty and doubt. It's Fukushima! It's a nuke plant! It's a government plot! Counts are increasing systematically everywhere! It's blah blah!

                  I would urge anyone to get their own GC, learn what it can and cannot do, and share results where possible. The existing networks are far too sparse to draw valid conclusions about subtle patterns. Thousands more stations would help a lot. By the way, I'm a pensioner, so I'm not too sympathetic to the "can't afford a GC" argument I often hear – it's a choice thing.

                  • There is a big difference between irresponsibly spreading fear and making people aware.

                    I could also be said that the reverse is true. Telling people that it's always an anomaly so as not to be concerned sounds very familiar to me.

                    Just to be clear. I have never stated I thought there was some government plot.

                    I will however, say it, and I will say it again…

                    It's NOT "blah, blah". It's a simple observation and people can take it for what it's worth. I've always said that.

                    See my latest observation below.

                    …and maybe rad maps too. 🙂

          The Oregon station went over 4500 CPM before it went off line on the 2nd November. A poster Yogda on enenews at the time said, he was 80 miles North, and his Geiger counter was at normal levels.

          Stations around an event may not show detections. For starters they can be a considerable distance apart, or the other station maybe upwind. If you do see other close stations showing elevated readings at the same time, this tends to confirm that an event has happened. That it is not likely to be an isolated malfunction.

          You can get very narrow band high level fallout coming through to a localized area. This chart of a Dunedin New Zealand 1st February 2012 rain event captured such an event passing through the area.

          During a large detection event a Geiger Counter tube can suffer from saturation, and go to zero until it recovers. This can happen when a large amount of radiation is detected. That seemed to be what happened to the Oregon station as it went to zero, and then recovered, when I was observing the event.

          I had this happen to my Geiger Counter when I detected a radioactive cloud passing over our area in January 2012. My Geiger Counter went to zero, and then recovered. You can see it in the data chart taken of the event. The big dip just before the peak.

  • It's All Lies It's All Lies

    As I mentioned earlier in the page about a huge spike on the Eurdep radiation monitoring for Europe, there's been another huge spike on the same monitor!

    The other was on the 29 October. This one was on the 4th of Nov (6am).

    It's in nanosieverts but converted it's 70,000,000 uSv/hr.
    Either they have a serious problem with their monitor, or the plant's ongoing works are more than meets the eye!

    • vital1 vital1

      It's All Lies, thanks for the detection info.

      These are huge numbers for both events. If this genuine, and not equipment malfunction, there are a lot of people at risk who are down wind of this detector. This detector seems to also have a lot of down time.

      There are hardly any European independent Geiger users providing information on in this forum. You would think with so many Nuclear power plants in Europe their would be more European people providing details.

      Archlight also use to provide a lot of Eurdep event info here.

  • It's All Lies It's All Lies

    Hi Vital1,

    They are huge numbers and I've found yet another one yesterday at around 12:00. The figure for that is in the millions. It's insane. I would say it's an error but the plant on top of it had a fire last year and the readings at the exact same date were high. Considering they are doing work on it, it'd be better to safe than sorry.

    There aren't many independant users on here at all from Europe. I've got a geiger and I'm very comfortable now with what I'm doing in the UK.
    Arclight used to do some good stuff, but has he been on here much?

    I've joined a radiation group with people around the world so I've been in the background here recently, but I will start posting readings again!

    • vital1 vital1

    103 cpm in Minnesota write now.

  • HoTaters HoTaters

    Radiation Network for northern Wisconsin showing 92 CPM at 1:40PM Pacific Time. Got a screenshot to corroborate this. Bouncing up and down between 60's and 80's pretty regularly this afternoon.

    Also lots of high readings in 50's and 60's all across the country — notably San Jose, CA, Colorado, New York, Midwestern locations.

    What's the jet stream doing? We're getting rain here in the S.F. Bay Area.

    • HoTaters HoTaters

      It's hanging around 84 or 85 quite a bit right now in Minnesota.

    • Excellent observations.

      Several months ago it was odd to see more than 1 or 2 (yellow dot) locations above 50 cpm.

      Now many locations hover around or above 50.
      I saw Montana above 50 today, that was odd.

      The average when my eyes scanned the screen from about mid summer up until a couple of weeks ago was 3 or 4 locations above 50 cpm.

      Now it is not uncommon to see 7 or 8 locations over 50.
      Along with 60 and 70 cpm plus, regularly now.

      The micro-alerts above 100 cpm, are happening more too.

      Add in the independent rad detectors around the world + Add in the low ball disinformation when it comes to reporting data and the conclusion for me is that have been and are under FALLOUT conditions with no response from any agencies regarding the need for mitigation and/or some contingency plan. 🙁

      If being at an alert level of 100 cpm is not good for you over time, then being at 72 cpm 'regularly' like in Philidelphia, PA most of the time, has got to not so good too. Just sayin'.

  • vital1 vital1

    Theremino from Italy, have created excellent free computer Geiger charting and metering software. You will need a Geiger Counter with a sound output, that you can connect to a computer sound input, to use this software.

    You also need two programs, to get the Geiger software up and working.

    Download the Theremino Audio input program, an unzip and open it up. You need to set this up correctly, to get the Geiger audio input trigger level right, for the Theremino Geiger software to work. The Theremino Audio input program is at the bottom of the Downloads/multimedia page at the site. The Theremino Geiger software is in the Downloads/uncategorized section.

    I am also using the new Theremino MCA spectrometry program, for spectrometry food testing.
    A Scintillator can be set up to use the Theremino Geiger software. This turns it into a very sensitive Geiger Counter.

    Select English labeling under the language menu item, in both software packages. You can also send charts to the Internet via FTP. Both programs are constantly being updated with new improvements.

  • 'blip' – Observing 10 locations over 50 cpm across the map.

    I have never seen this many at once, over 50.
    Some locations that were showing over 50 earlier are now offline. So it really could be even more.

    Here's the screen shot.

    Obviously, I am not fully qualified to make such observations because I'm not a PAID member of Radiation Network.

    Is this a trend? I don't know.
    What do you all think? Tim? Anybody?

    • aigeezer aigeezer

      ChasAha said:

      "Obviously, I am not fully qualified to make such observations because I'm not a PAID member of Radiation Network."

      The members of the radiation network have presumably paid for their geiger counters and have paid (about $60-$80 one-time) for the software to connect them to the radiation network so you can see their results (for free). That is the only payment involved.

      Anyone can do this. What is needed is more data – more stations reporting, not more speculation about the little data we have.

      • Speculation -> It's akin to FREE speech.
        (my opinion)

        Yes, we really do need more data.
        Yes, we all need Geiger counters.
        NO, we do not need to stop speculating.

        1. A conclusion, opinion, or theory reached by conjecture.
        2. Reasoning based on inconclusive evidence or supposition.

        We don't have more data and we don't all own Geiger counters so what we are left with IS speculation. I have a feeling the Nuclear Industry wants to keep it that way too.

    • PhilipUpNorth PhilipUpNorth

      As the Fuku Crisis has unfolded, many 'Newsers have voiced alarm over the increasing radiation reported on Radiation Network. As I have observed here many times, the trend has been upward ever since 3/11/2011. In 2012, the readings have continued to trend up, and now are at all time highs. Let me be clear about this: Radiation Network readings are trending up from radiation coming from Fukushima. (The radiation is not from uranium mining, local nukes, radon from basements, etc., etc.). The increase in radiation above background readings of 9 or 10 cpm is directly attributable to Fukushima. We know, because since 3/11, the radiation levels throughout the US have steadily increased over time. They were higher in December, 2011, than they were in March, 2011. And they are higher now than they were in January, 2012. (You don't get higher and higher radition reqdings from uranium mining, local nukes, radon from basements, etc., etc.). Got it? My contention is that the increasing radiation levels throughout the US are due to the increasing radiation pouring out of Fukushima into the air from underground coriums. I expect that fallout as the Fuku plume passes over the US again and again has caused an ACCUMULATION of radiation throughout the US. Accumulation may be a part of the increase in radiation. But the bulk of the increasing radiation being reported in recent months on Radiation Network must be due to INCREASING radiation from the underground corium.

      • many moons

        And if it keeps going up…imagine one day we may be looking at 200 cpm background…average.

      • +1

        You clearly stated what I was thinking.

        When one realizes that the initial fallout(s) have circled the globe over 15 times now and it's accumulating as it goes, then there is no way this 'goo' is not adding up.

        common sense vs speculation

        At some point it's no longer 'speculation'.
        Maybe we've reached that point.

        PUN certainly seems to think so.

        • PhilipUpNorth PhilipUpNorth

          many moons: I do not see the beginning of a topping out of Fuku radiation increase at present. We may certainly be looking at 200 cpm averages across the US in coming years. And if the greater part of the increase we are observing is new radiation coming from the corium, rather than accumulation from the March 2011 plume, I think the increases can go on and on, up and up. 100 cpm is thought to be a harmful level for human beings. The canaries are already dying.

          ChasAha: Fact: Radiation is clearly increasing over the US. Fact: The Government of the US is criminally covering up the radiation. 🙁 Decommission nukes. Stop construction of new nukes.

  • * I'm a member of Radiation Network. From whatever credibility I have here, I can assure you that we're mostly a network of plodding amateurs, often as perplexed as you are when high CPMs get reported.

    * If you take the trouble to read back through Tim's RM alert explanations at:


    –you will see several that end up being "real". They're characterized by a build-up, a plateau, and then a decline. "Real" what? –Who's to say? We/Tim try not to report more than we actually know –which is mostly: "click-click-click".

    * The very fact that you're seeing repeated "Alerts" from those stations in Minnesota and Wisconsin speaks to our integrity. The simplest thing would be to turn them off –but Tim only does that when a station is known to be defective or accidentally subjected to a non-environmental source (like bringing home a radioactive antique hand compass).

    * There are places where the background is high and it has nothing to do with what's blowing in from Japan, or blowing off from a nuke plant. The St. Louis area has a wicked history of loose nuclear wastes and I have to wonder how much of it still blows around when it storms. Brazil has amazingly hot beaches < >, there's a radon contour for the United States that's highest mid-continent and lowest —

    • –at the coasts (or: as is assumed). Complicating that are large volumes of radon escaping from vast piles of abandoned uranium tailings plus radon evolving unevenly from beach and dunal sands. That stuff blows around. Now factor in solar flares.

      * In Germany there are 1800 stationery monitoring stations –!


      –all the same (meter high, ground mounted outside in a clearing, sealed in a standard enclosure, gamma (and maybe high beta) only, each intelligently sited, all of them publicly accessible, EACH with history graphs (just click on any one of those dots).

      * RN consists of a variety of hand-held Geiger counters with various sensitivities, some of them are really good instruments, some of them home cobbled, some of them antiques, some bargain basement, some read alpha, some don't. Everyone has their own gnotions about where to place them: inside, outside, in fan driven air ducts, over rain troughs, on the window sill, in a plastic bag, naked and exposed to the elements, heated, not, laying on a desk top. (So: we're a bunch of volunteers.)

      * I can tell one thing for sure: the national average of all of our monitoring rigs has hardly budged for the whole time I've belonged. Ditto for my gamma readings here on the west coast of Oregon (since March 17th of 2011).


      • The German Map is impressive looking. I really like the history view aspect.

        If I lived in Germany, downwind of Areva, (I mean France), I would sew a dosimeter into every pair of underwear I own. 🙂

        • aigeezer aigeezer

          ChasAha, since you apparently don't live in Germany would you consider instead setting aside your sewing kit and getting a dosimeter or a Geiger counter or a scintillometer or some other actual measurement device of your choice so that you can measure and share results with us from wherever you are? Please?… pretty please?…

      • Radio VicFromOregon

        Craig-123, thanks for the intro and explanation about RadNet. And, of course, here in Oregon we have lots of pockets of radon and lots of granite, not to mention Hanford in Washington State leaking nuclear waste that is heading towards the Columbia River. So, being able to tell one type and source from another is one reason why the government needs to use its spiffy geiger counters and the ability to collect identifiers. But, without you folks, i don't think they would be so motivated. Something about who watches the watchers? You do. So, thank you. I tend to agree with the analysis that most of the initial radiation went into the the Pacific Ocean. So, it will spread much differently than airborne released save for what might have evaporated from the ocean surface. But, given that the Pacific took such a large drop of fall out and that the stuff at Hanford should be hitting the groundwater in just a few more years – it is now 50 feet away from the shore? – is there a way that RadNet can detect for water rather than air without having to scoop and send off samples?

    • Thanks Craig-123.

      I have read through the alerts (several times) and you are correct there are some that have ended up 'appearing' as real or unable to determine.

      I know that radon plays a part in some areas, but I think we are getting more of it than is historically normal perhaps. Which would not be a good thing. That should be mentioned. Again, a non-qualified speculation only.
      (based on potrblog testing I've watched)

      * Have you ever seen 10 locations or more over 50 cpm?

      Maybe you haven't looked like I do? Maybe somebody should, because if this is a first or at least a very rare occurrence then it's possible' that this says something. Or it's just another anomaly. Those who have more (historical) data and are perhaps more qualified than I could give their opinions. I'm okay with that.

      Many times 'experts' are afraid to speculate out of fear of embarrassment. I think they need to get over that issue especially when it comes to radiation and fallout. We are entering new era here, we need speculation which could lead to innovation.

      • Radio VicFromOregon

        ChasAha, i agree. We, then, too, need to give them room to brainstorm and think outside the box without calling them stupid lying bastards for changing their minds. I think you are bringing up a incredibly important point. You don't get innovation from restricted thinking and innovation is what we need. But, your idea that "many times experts are afraid to speculate out of fear of embarrassment" says something really, really interesting and vital – they would like to speculate, mix it up, brainstorm. Most of these people are problemsolver thinkers and would secretly jump at the invitation. Many social conventions restrict them for good and bad reasons, including wanting a paycheck and to fit in. Would you be willing to start a thread on the off topic site about this?

      • * Mr. POTR lives in the St. Louis area, so I worry that he's got "legacy" contamination to contend with (per:


        * Unfortunately: in the course of an afternoon, and by taking only minute-long averages/updates, the normal range of our CPMs might run from 18 to 54 CPM for our best Geiger counters in a rock steady 10uR/hr field of background radiation. That's due to the random "Poisson distribution" nature of gamma detection. A small tube GC might run 4 to 22 CPM in the same field.

        Consequently, our "Alert" level has to be set rather low for the the large tube GCs, but quite high for the small tube GCs.

        * The distribution of CPMs could be reigned in by going to (say) 10 minute averaging, but any alerts would be somewhat delayed, and a sharp spike might get largely averaged out.

        Since ever more stations are joining Radiation Network, you'll keep seeing more stations which just happen to be reading high at any given time.

        * If you'd like to see some history, scroll down from here:


        The lower line is long average background gamma. The upper line (where present) connects wild-hair radon readings off of my air filter draws: interesting, but pretty much meaningless, and all short half-life with no residual radiation.


  • It's All Lies It's All Lies

    Hi Vital 1,

    I'll do my best to post readings on here and any info I can dig out. Were quite thin on the ground here compared to the USA, and we also don't have a radiation network. We have Eurdep but alot of the features have been gutted and the stations in Russia have gone completely. Arclight regulary mentioned it had been scrubbed many times, so I'll only use it as an aid not a reliance.
