        Dear Xdr, The first link were measurements on a beach below the high tide line. Water vapor in air does concentrate aerosolized radionuclides, but copious amounts of uncontaminated surface waters (ocean, running the hose over something, flooding, etc.) will wash away contamination. I believe it is most intelligent to take readings, not of air, but of where the radionuclides are most likely to accumulate most, which would be in sediments that do not drain away after a rain, the rain itself, or surfaces that concentrate radionuclides after rain. We’ve seen a number of these sorts of readings from Japan where the sediment in a drain (and it rains a lot in Japan) that did not wash away, had more detectable readings. One of the reasons I advocate for this sort of testing approach is because most of our instruments, including the ones that were used by Dutch in the above tests are not sensitive enough to detect radionuclide aerosols in air and can only detect them at all, not because the rates are NOT higher than normal, in sediments and in the “hot” rain.

    You have to understand that this Geiger counter never moves its needle, but March 21 it started going crazy it was picking up the fallout from Japan.This Geiger counter is the CDV-717 wich picks up heavy doses of radiation unlike the CDV-700 Geiger counter witch can monitor low levels of radiation so that day something defiantly came through Texas.

    Ashland Oregon USA – Using a Radalert 100 (see http://www.geigercounters.com/Radalert.htm for specs) I have noticed a slight increase over background counts over the last 2.5 days. Our typical count is 14.2 cpm (averaged over 60 minutes taken outdoors in my backyard). The most recent measurements have been 17.3 cpm (averaged over 60 minutes same location). This is a 22% increase. While these levels are not alarming, the cpm has only been above 17 twice over the past 6 months (each time after it rained) and then only for a few hours. This has remained at or above 17 for 3 days now. Weather has been sunny-partly cloudy but no rain.

      shaktasna999, I can’t remember where you are located; I know you are in CA, though…

      What kind of geiger counter did you get? We have been testing around here some, so far haven’t found any really hot spots, but plan on looking more. There is a lot of area in the bay area!

      Anyway, for anyone who is in the SF Bay Area, I wanted to post this again: my friend and I are considering going in on a more expensive geiger counter. If there is anyone in the area who could pitch in and help with testing the area, it would be a great help. Please post a reply; if I don’t get back post it again in case I missed it.

      I would also like to get together with a few people in the area in general to try to take some kind of action. We are trying to make a documentary about the whole subject of the meltdowns and its effect on the US, particularly the west coast. My friend has great camera equipment and knows a lot about film. Anyone who can participate would be helpful.

        I recommend getting one with a pancake detector that has an open window to support detecting alpha. If you are just connecting to a PC the Black Cat GM-45 is very nice. The software is great for monitoring and graphing readings! The downside is it’s not very portable, as it needs to be connected to a PC. The RS-232 version is a bit cheaper than the USB version, but comes with a USB adapter.
        http://www.blackcatsystems.com/GM/products/GM45GeigerCounter.html

        For handheld, something like the Radalert Inspector looks nice. Big sensitive pancake detector. No PC connection, but it has an audio output and some radiation monitoring software can trigger off of the audible click. Only downside is it seems the wait is several months for these. Both of these look nice.

        I have one by Images SI as a portable unit. Not bad, and the wait was not as long as other units. It is not as sensitive in terms of CPM as the GM-45 but overall is giving similar readings.

        I was able to get a DX-2 geiger counter in June. It’s a good solid low end model. I would encourage everyone who can afford it to at least try to get a low end model as that’s all you need to make an effort to keep family and friends safe. Obviously we can’t count on the powers that be to do that.

        I recently was able to upgrade to a higher end model, a Radalert 100. Both counters are supposedly factory calibrated with CS137. I was surprised that my readings with the Radalert are consistently lower than with the DX2. Does anyone have any ideas on why? I’m thinking its a difference in calibration or sensitivity. The DX2 is only supposed to detect 3 of the 4 types of radiation whereas the Radalert detects all 4 types which is why I thought its readings would be higher. The DX2 has much more of it’s geiger tube exposed though. The difference is usually within 4-7 cpm.

          I have an unfounded suspiscion that there was a nice big long choke hold on the companies making GCs and that is why it took sooooo long to get them and then when we did get them they “could have” been calibrated low. I mean, really, we are at the mercy of the companies that make them, and we can only hope, that they are not being strongarmed by the govt to calibrated any other way than correctly. Having said that, your readings are more than twice lower than mine and I am not that far from you.

  • About a month ago I called Senator’s office ( Bernie Sanders – VT ) and asked him to sponsor legislation mandating the monitoring of the air, water, rain and food for radioactivity. They said someone would get back to me. Today I received a letter from him which mentions jobs, social security, the deficit and a number of issues currently making news …. but nothing about radiation monitoring. So I called his office again and requested that someone call me so we can work on legislation requiring the government to monitor and report on radioactivity. I encourage you to do the same.

    Northwest corner of Pennsylvania taken with a Radalert 100 Sept 16th. All readings are 10 minute averages.

    In the dining room about 10 ft away from my homegrown garden produce: 12.4 cpm

    Muskmelon from my garden that’s sitting on the dining room table after it’s been washed in baking soda and water: 11.9 cpm

    Tomatoes from garden that are on dining room table after they’ve been washed in baking soda and water: 12.8 cpm

    Outdoors with the Radalert laying on the front lawn: 17.6 cpm

    I’m most interested in how contaminated my produce is when it’s ready to eat. Next time I will try to do readings before I wash the stuff then afterwards. Would be interesting to see if there’s a difference.

      Radiation fears, shipment bans, weigh heavily on mushroom pickers, growers, Mainichi Daily News, 17 Sept 11
      “The ban came after wild mushrooms containing cesium beyond the legal limit of 500 becquerels per kilogram were found in the prefecture. Tawny milkcap mushrooms containing cesium over the legal limit, meanwhile, have also been found in Takahagi, Ibaraki Prefecture, endangering mushroom-picking in that region as well.

      In the town of Tanagura in Fukushima, tawny milkcap mushrooms picked this month were found to contain 28,000 becquerels of cesium, or 56 times the legal limit. The town is famous for matsutake mushroom hunting between the end of September and late October each year”

      Try google but from what I found in wikipedia under their bequerel definition it doesn’t look like it’ll be an easy conversion. Here is a portion of it, you might want to read the whole page. I got lost ……..

      Bq versus counts per second

      When measuring radioactivity of a sample with a detector, a unit of “counts per second” (cps) or “counts per minute” (cpm) is often used. These units can be converted to the absolute activity of the sample in Bq if one applies a number of significant conversions, e.g., for the radiation background, for the detector efficiency, for the counting geometry, for self-absorption of the radiation in the sample.

        Dear Chem: thank you. You know what I would really like to see and I still think it’s possible (not apples and oranges as they say), is to have a conversion (an educated guestimate if that’s all that’s possible) of bequerels to sieverts or counts per minute to sieverts or dpm to sieverts. Since there is a lot of dosimetry information tied to sieverts, I personally feel the best conversion information should be to sieverts whether or not the engineers think that’s possible, I know it’s possible, somehow. Some disclaimer concerning margin of error converting from a known dpm to sieverts (an assumed absorbed dose rate?) could be included; but it’s definitely definitely possible. I don’t dare try to create a calculation myself as I’m not the most high maths worthy. Hinting that others might take this up. Forgive me if someone else is already doing this and I’ve missed it (particularly if it’s been posted repeatedly or is above at the tabs on ENE)

So the “637″ reading is for 10-minute interval? So would that be an average of 63 cpm for those veggies the GC is sitting upon? Wow.

    Folks, great to have lots of numbers, Fantastic effort and keep it up.

    Do we think that we need some sort of benchmark with each report so we can understand if a report is significantly away from normal.

    Im not sure how to do that but if I think of my own home, where would I find someplace to put a counter to get some sort of ‘standard’ that could reflect pre-fukushima times?

    Maybe a cardboard box say at least 300mm cube (one foot cube) or bigger to provide a radiation shield from other sources and a stable sample. Make a cardboard ‘pipe’ just big enough to hold your counter’s probe in the side of the box near the floor level. Fill the box firmly with clean dirt you have dug from a dry spot- discarding the first 100mm (4″) of dirt (From under your foundations or a dry corner of the garden in the shelter of a fence). Shove your meter in and record the result. And then do that with every report to see how far away from your local standard things are, and give us both readings “My standard is xxx. My readings taken at here there and everywhere are: xxx “?

    Otherwise all these data are doing is letting us compare cheese with chalk with fog; interesting but not helpful.

    Could we give that method a go?

    * I’ve been posting my own air sample readings at:
    > http://webpages.charter.net/123goto/map.htm
    –where you’ll find links to other monitoring plus descriptions of my methods.

    * To make such efforts useful, they should be done in the same place and in the same way over a long period of time with clean equipment. After a while you have a local “base line” of readings which help you evaluate new readings.

    * It takes a 10 minute long count (then divide by 10 for the average CPM) to get useful readings. Since CPMs are peculiar to the instrument being used, the result should be reported as common Cesium-137 calibrated micro-REM per hour (uR/hr) equivalents –which provides a rough equivalency between Geiger counters. (I suggest uR/hr instead of milli-REM or micro-Sievert. If you don’t know how to convert between CPM, uR/hr, uSv/hr etc, you need to read up on radiation monitoring before publicly posting your results.)

    * Straight (on the) ground, (close to the) rain water, and elevated air readings will alert one to really serious fallout, but you need to concentrate what you sample and read in order to detect the “hot particles” that we’re currently worried about. See my link for suggestions.

    * When you post your results at Energy News, it would be helpful to include your local base line average for a week or longer (perhaps excluding any days with unusually high readings).

    I own 3 CDV-700s, all are now reading 14cpm, with the probe closed, which means it is gamma radiation. 14cpm indoors and outdoors. Probes open, they go to around 16cpm. They didn’t do this before. All summer they wouldn’t register at all with the probes closed. I am in NY.

      Dear pg: That’s interesting stuff. That’s VERY cool that you have three geiger counters as an accuracy test sort of thing, I assume. There was a very good video on ENE a few days ago with a European lady doing some serious scientific testing of a soil sample. She had mentioned that our personal geiger counters are of limited sensitivity. Therefore, we might extrapolate that WHEN our geiger counters do register anything that the situation might be worse than it appears in the readings we take. Also, she said and it has been said many times before, that many or most of the at-home use geiger counters are really only calibrated, if only initially from the manufacturer, to read Cesium nuclides, and most do not read for alpha or beta emitters. I very much appreciate your post and hope that we can eventually get hundreds or thousands, or more (real dreaming there–I hope not)to do the same. Very worth it. Thank you.

        Sure no problem on the readings. I actually have many cdv-700s, several of nearly every type from 59 to 64, but only three are restored, working, calibrated. The rest need restoration. I would like to have them all restored by the end of Oct.

        My brother is not far from me and he has a gamma scout so between us, we keep a close eye on things. Much of the time one of us will detect something, then we get together to figure out the source. This gamma bit is a little alarming, coming it a 14cpm in my basement. Its almost like it is coming from space. Seeing the Sun and black holes can give off gamma, I was thinking along those lines at first, but even with the Sun down, they still tick up non-stop. Just not enough hours in the day to piece it all together sometimes.

    I knew if I looked around long enough I would find the easy way to understand how to get from mR/hr to uSv/hr. The picture for the St. Louis report and the title was helpful since I had asked this question in the past and did not get an answer:
    mR/hr1.335 equals 13.35uSv/hr

    Southern MI- mostly 12 hour reads inside through plastic bag.

    uSv/hr on the ground is ranging between .008-.014.
    Same for the air.
    The Chaga I measured was .022uSv/hr.
    I’ve measured trees and moss and stumps and garden soil and veggies and I really did not get readings different from the above u/Sv/hr.

    Something just interesting happened. I was out measuring in the yard and a squirrel ran up to me and stayed about 4 yards away. He had a big nut in his mouth and he just watched for a good 2 minutes! I wonder if the GC noise sounds like squirrel chatter or something.

    As far as CPM to Bq- would we need more sensitive equipment to get DPM? If we could get that then we could get to Bq/l or Bq/kg.

      Sorry about the squished together info above. I had it separated into 2 columns but when I hit send it squished it all together.

      Also, remember everyone to not do your readings with the sun shining on the GC and also not on top of bricks or granite or tile. I was getting 100CPM in the house through a plastic bag when doing readings on top of those materials.

    hi from Maine. we have a CDC 715 we just got from ebay…we are getting really big readings. on the x0.1 scale i am getting anything from a 1.2 to a 3.0 which i understand as .120 milliR/hr which equals 120000 uR/hr, is that right??? i have attached a picture please help. it looks like we are getting a years worth of radiation in one hour.

      Please understand that the math part of my brain is wrapped in Saran Wrap but as I see it:
      mR/hr .12 x 0.1= .012mR/hr =.12uSv or microSieverts
      for that moment.

      The readings bounce around so maybe you are going to have to eyeball the average over 10 minutes.

        hi we leave it on for long periods and it will stay around 2.XX. the geiger counter measures R/hr. so my understanding is lets say 2.2 x 0.1=.22R/hr=220mR/hr=2200uSv or 2.2mSv

        i used this to get to sieverts…because all those zeros get confusing.

          Your calculations look right to me.
          That’s high (as you pointed out). Yikes and I hope we have made a mistake in our math somewhere but, from my non-math thinking brain, it looks like your math is right.

          Do you know about the calibration of your GC? Maybe that could have something to do with it.

          I made a mistake in my first reply to you- I missed that your GC is R/h not mR/hr.

      Hello teacherep.

      The meter you are using (715) is designed for ground zero work, search and rescue, and for the locating of ejected material (high level material). It can also be used to help evacuate away from high levels of radiation. It is far too ‘insensitive’ to be used for measuring radiation from a distant disaster. A meter like that would be useful right at fukushima say, if the workers were looking for hot spots. The meter you are looking for is the CDV-700, which is far more sensitive and designed to pick up radiation at very mild levels. It is also designed to find radiation in foods, fluids, ground samples, even on people. It also has an audio port so you can count the radiation packets’ as they pass through the probe. That is very important in the beginning of a disaster because the gauge needle will barely move at that time. Once you can no longer count clicks because there are too many, then you start to use the gauge. What you would need to do is try to ‘count’ how many times in a minute your meter clicks. Normal for your area right now is around 10-15cpm. When the 700 series (set at the least sensitive level) is maxed out, that is when the 715 series meter is used. If you were really getting that high a level, you best a) have a NBC mask on, b) be indoors and better yet in a shelter, c) be taking potassium iodide tablets, and d) have a good understanding where the radiation is coming from so you can make good decisions. That 715 you have needs not…

        That 715 you have needs not only recalibration, but needs a new transistor, capacitors, and diodes. From there pray you never see that needle move like that again. You need a CDV-700 or a digital meter.

    Hi, fellow nuke haters!! I live Melbourne Australia. I got my Pripyat PKC-20.03 counter a few months back and have done many tests and samples. I never really had to many high readings UNTIL NOW!!! :( It had been raining here for a couple of hours last night with NW wind, so I did a test not thinking much of it until the counter got close. 3.35 uSv/hr (WTF?) on rain sample taken from my car. I got the video camera out and got it on film and will upload and post the link.People have to know!

      Thanks. That’s a bummer that the car reading was 3.35uS/hr. : (

      I know they did some mining around Melbourne back in the day- out in Warrandyte. But, that was for gold. Your background uSv/hr is higher than here where I am. I wonder if there was nuclear testing that blew over or if there is some natural substance in the background making it read so.
      And you are not doing the test over granite, bricks or tile or with the sunshining on the GC ? I have a gaggle of friends in Melbourne. I want you all to be safe.
      Thanks for posting.

    Wow.. what a day! (slurps apple juice) …. I was hoping to tell you that the last 60 hrs or so have been giving normal readings! And indeed they had (first normal range for 20 days approx.).. I have posted my findings above…they were not health threatening levels though! But nearly double normal….i was going to give you my theory that the 21 august ejections from daichi were beginning to clear from uk skies…..until I turned on my Geiger at about 11 0`clock gmt….

    Readings from in house (doors and windows closed)
    0.4 mcsievert/hr first reading then readings of 0.3, 0.25, 0.28, 0.2 mcsievert/hr !!

    I quickly got on my motorbike and clamped it onto the inside of my windscreen inside a ziplock plastic bag
    Readings taken from 10 to 60 meters heathrow to elstree studios

    0.1 to 3.2 mcsievert/hr
    readings taken from 100 to about 130 meters elstree to hemel hempsted

    0.1 to 2.5 mcsievert/hr

    readings taken at hemel Hempstead over 30 minutes
    normal range
    wind picked up and briefly got a 0.3 mcsievert/hr

    heading south my readings concurred with my northward bound journey

    this got me thinking, so I found a sheltered spot and did a ground reading while covering the Geiger from the wind as best as I could and got normal readings until the wind picked back up and the gieger went straight to 0.22 mcsievert/hr! test complete! It was in the wind……cont

      Latest readings 7 o`clock gmt
      0.7 to 2.2 mcsievert/hr seeing more under 0.01 mcsievert/hr

      went to the criirad site

      - Operational Beacons: 6 out of 6.

      - Results of controls: no contamination was detected by the beacons of the valley of the Rhone. They are measurements taken uninterrupted and in real-time and the limit of detection is thus relatively high (about 1 Bq/m3).
