    Another important item is do not go outside when it is raining. The water on my pants, which were dampen from it, caused a burning sensation to intensify. Immediately arriving at home I took them off and put in the laundry and took a hot soapy shower. I do believe that just drying wet or damp pants do not solve the problem and if you wear them again- your perspiration will only reactive it, from my at least my experience. Whether the reactive is acid rain or chemtrail fall-out or radiation, I don't know. I tested the rain about 9 months ago and it was 40 to 50% above background, then about 3 months ago it was 90 to 110% above background according to my Inspector Alert which indicates radiation…

    • * Here along the coast of Oregon, "not going out in the rain" is hardly an option during the rainy winter season. But it doesn't worry me (yet).

      * It's probably the case that some people can actually feel beta (and alpha) radiation, although I've not noticed it. It would be interesting to find out –by surveying folks, using real and dummy radiation check sources. (The handiest beta source is "salt substitute", of course.)

      * My scores of filtered air draws and a number of "wipe" type rain and dry tests in the early days after 3/11 –all decayed in a fashion which indicated radon daughters. None of them had detectable residuals, although there should have been a trace of lead-210 on those filters. The several that I sent away for gamma spectrometry were unremarkable.

      My station might possibly be catching radon that's being lofted over here from Japan (it's less than two 4-day half-lives away by jet stream, after all), but I have no evidence for other stuff. (Unlike Fairewind's finding that hot particles hit well north of here, in the immediate aftermath of 3/11.) (I think I could detect a "hot particle" if my 40 cubic meter air draws snagged one.)

      * We'd need a disciplined, standardized private network with freely available data –in order to get a handle on this stuff! Several of us had the 30,000+ Wunderground system managers interested, but the effort fell apart. –Dang.

      Here at my location in Australia we have had some very large Radon 222 and Radon 220 fallout events in 2012 and 2013. On a scale that I would certainly suggest staying out of the rain if possible, and having a shower later if you got wet.

      When these events occurred there where also significant detections of Iodine I-129 and Beryllium Be-7.

      The question is what caused such large radon washout events? They were significantly larger than pre-Fukushima radon washouts events.

      The Theory put forward was that the large amount of Uranium nuclear fuel aerosol into the atmosphere from Fukushima was creating it.

      • Good advice.. even 'natural' radon has a bite to it. Use an umbrella if you must get into the rain, rubber boots, etc. Protect yourself.

        One rainstorm can be completely harmless and test 'normal' background. The next can be hotter than blazes. No way to tell unless you do a wipe test.

        And with WIPP and FUKU plus God knows what else doing invisible 'puffing' of spikes of radiation, that stuff often comes down in rain hundreds to thousands of miles away, downwind.

        Feeling lucky?

        For all those drinking and bathing in roof collected rainwater, add sand and charcoal filters, and test every rain if possible, before collecting it.

        If it tests hot, Let it sit and see if the radon evaporates out in a few days or a week..

      Note: Geiger Counters have different sensitivities. Meaning, at the same location one Geiger counter model could show say 12 cpm, while an another 120 cpm.

      It all depends on the type of Geiger counter tube the model it is using. If they used a scintillator for detection purposes, which is very Gamma radiation sensitive it could be in the thousands of counts per minute.

      You can only compare it against itself. If it usually averaged around 12 cpm at that particular location, this would be considered the background level at that location using that Geiger counter.

      It may not be unusual to get detections for brief periods of time, 3 times this. If it stayed 3x or more background for any length of time, then possibly something more serious is happening.

      This information I provided in this post is only meant to be a
      generalized overview, as each circumstance is different.

    2. Researchers finding that decontamination efforts can sometimes create more contamination downstream, after snowfall and rain events.

    3. Soil contamination levels do not reflect what food contamination levels can be, because different plants have different biological efficiencies in contamination uptake.

    Thanks Craig and Vital, you input is greatly appreciated. Yes, I probably am sensitive as I am to electro-magnet fields, cell towers, etc. An environmental Dr. told me I was like a canary in the coal mine and I am somewhat happy for that. Driving at night on a freeway I have noticed small fog patches that show up purple here and there on the road and in the ditches. It occurred last June and started about 3 months previous, but I haven't seen it within the past few months. I was wondering what isotope it might be… Also I did not have my Inspector with me.

    • * The resources at "A Green Road" can be quite a revelation. An edited quote:

      "As radioactive carbon levels keep rising globally due to nuclear accidents and normal emissions from nuclear plants, plant growth and CO2 absorption is slowing down … which accelerates the global warming tipping point, specifically in relation to CO2. As this gets worse, more … stressed trees and other plants will die off … Mass die offs due to insect and disease attacks will become more … common as stressed and radiation damaged trees and plants are affected with greater concentrations of radioactive Carbon 14 … The nuclear energy industry is covering up and denying the fact that they are indeed among the largest contributor [to] global warming, compared to all other carbon emitting industries."

      It is _wrong_ (of course) that the average citizen should be called upon to even be aware of such issues –in order to be an informed participant in the electoral process. We need the option to simply vote for a social/political philosophy –a political party which represents our welfare, our spiritual connectivity.

      We do have that option, but with each election, 90+ percent of us gets flummoxed into that old "lesser of two evils" paradigm. They play us like a fiddle –or a "Wurlitzer".

        …I wanted to enjoy it as natural, normal day before Fukushima ever happened, I needed to let the rain touch my face and skin while the fresh stormy air whipped around me, I needed a moment of normalcy because I used to love walking in the rain and when windy days made me feel alive – but my day dreaming was shattered by the sound of an alarm of silent hot particles passing through the air I was breathing and the radiated rain drops on my skin. I mourn for what used to be, life will never be the same, nothing can stop this steady stream of radiation infiltrating, permeating, poisoning every living thing now. I took a shower, threw my clothes in the washer, sat down and came to enenews to report my periodical measurements from this little corner of the world. It's difficult going through this alone and I'm thankful I can at least share my thoughts here with like minded people. Incredible sadness and grief as a human being goes to the innocent animals, critters, plants and to this beautiful earth for allowing this catastrophe to happen.

        • I must respond to your plaintive lament.

          * Decay and death are certain –something's going to get each of us. In the mean time, there's quality of life to consider.

          * Children are a pressing concern in this respect, but the quality of a precious childhood also weighs heavily.

          * It's best to start by questioning our assumptions. Is whatever's in the rain "that" bad? How terrible to deny one's self or one's children the simple joys of the outdoors and Nature –because Mom and Pop bought into a particular over-reaction/protectiveness of the day.

          * So let's say that walking in the rain or frolicking on the beach carries some degree or other of radiological hazard. Let's say (say) that it's actually long been a hazard –now incremented (_say_) 10% by Fukushima (hell: I don't know) AND that in our own carefree "good old days" (Chernobyl, bomb testing) it's been drastically worse. Would that influence our choices?

          * At any time, the United States could suffer its own "Fukushima" (many, in the case of a national power blackout [a Solar flare, a single high altitude EMP weapon]), precluding all further frolicking. (The pollution out of Fukushima is likely to vastly increase.)

          * There are other uncertainties: the overdue "super volcano", a great die-off due to (say) Ebola, a nation crippling asteroid impact, naked corporate fascism.

          Life and times are uncertain. Let's try to center ourselves as oases of peace, joy, and empathy –as best we can.

          • Rain is now a potential radiation hazard.

            The way to tell is to do a rain swipe..

            If that tests at normal background, have fun. Send your kids out to go and splash in the puddles, put their face up to the sky and stick their tongue out.

            Let them laugh and play in the rain..

            But it if tests 'hot', stay out of it and keep your kids indoors. It is probably radon, but it may also be something else.

            'Hot' Spikes of radiation coming out of places like Fukushima, or any other nuclear facility can travel thousands of miles downwind and then come down in the rain.

              Playing in the rain (or even worse…snow) hasn't been a safe Northern Hemisphere activity for the past 60 years. Regardless of a rain swipe test on a geiger counter.

              Too many radioisotopes that can't be detected on the basic detector. Strontium 90 is everywhere now… a consumer handheld device is not going to detect it. Same thing for plutonium and a hundred other long-lasting isotopes.

              Snow picks up airborne radiation from the troposphere several times more than rain drops because of surface volume.

              Umbrellas are our friends and if you do get drenched take a shower and hope the local water supply is not terribly contaminated. In central Japan unfortunately their aquifers and lakes are steadily rising in radiation content. They eat, drink, and bathe in an increasingly dangerous environment.

              Save your kids from becoming sick by keeping them inside as much as possible during rain events. We are all becoming radiation mutants from Fukushima and it is still out of control and spewing massive amounts of radiation every second.

              108 million seconds of radioactive air and water emissions from one of the world's largest nuclear power plant megaplexes. No signs of any human control after 1255 days of lackluster Japanese efforts.

              Sayonara Japan. You bombed yourself into a deadly Fallout Age.

    Hi Craig – thank you for your response, I appreciate your point of view and advise. It does sound like I overreacted to such a small incident such as rain, it was just one of those special moment I was taken by all the surrounding beauty and the first time the GC sounded a warning. I'm seeing physical changes happening to my body and mentally my short term memory has gone beyond the normal aging process. I read what others have said here and see those symptoms happening to me too. Though it's no comparison to some who've endured some painful, extreme illnesses here that is for sure. This information can be overwhelming sometimes, that's why I had to take a break from here for a few weeks.

    Yes, we can pass away at any time and I'm not afraid of dying but I'll try to lighten up a bit, it was just a bad moment and I felt the need to express my sorrow.

    Thank you again for your thoughts and insight.

      I can't imagine being in California these days… But, there is danger everywhere! I saw someone posting a funny comment about how it's hard to find a place to vacation anymore, thanks to all the international & environmental crises!!..

      I agree that's it's frustrating to feel like you have to immediately scrub off with baking soda, just because you get caught in a light summer rain…and then knowing full well that everything, including crops and critters are being exposed to higher levels of radiation via the rains…

      It's so mysterious though b/c I thought we were getting hosed in Virginia after Hurricane Irene (with three solid weeks of heavy rain!!!). It turned out that that rain actually had NO extra radioactivity, per many measurements, because of the wind patterns coming up from South Africa!!-!!… You just never know how life is such a chance! Did you swallow that one random particle of Plutonium or not? Could your body expel it? Do you have resistance?…

      That's why I pretty much have to give it up to Heaven Above and have a spiritual level… Good Luck!~

    Just a thought, I know and don't deny the real truth, but one must hold their head up high and get so involved in other things that life has to offer. For instance, I'm more concerned about getting a step pattern done correctly in the Argentine Tango then about all the radiation in the World at that peculiar moment or at a dance. I don't plan on dying until I am very proficient in the Tango no matter how long it takes to master. I believe reading the news here is great, but one must keep everything in prospective. Instead of concentrating on radiation every minute…find something to really get involved doing- whether it is volunteering services for others or a hobby or possibly working part-time. All is good. As everyone says life is short, so make the most of it…there are a world of things to do. Actually, I am so busy that I wish there were ten of me to everything that I am currently involved in. So the essence is to get involved or do something new or invent something to do. And never give up hope on anything…be positive. And when we all die we can go to that great party in the sky- drinking the finest wine and listening to all our favorite music while eating the best food. But while we are here…let's enjoy it and be happy even if this thing is occurring. "No hope creates no life" is my motto.

    Does anyone have any idea what the ultimate, worst-case total amount of radioactivity would be if the corium(s) keep fissioning, as they have been off and on since 2011? The quantities of I-131 in sewage sludge keep going up, not down. Tritium levels have also been rising in TEPCO reports since 2011. If there is no way to shut the damn things off, how may dozens or hundreds or thousands of years can they actually go on fissioning and making/releasing more radiation? Wouldn't ongoing fissioning alter current calculations of the "source term"? Does anyone know? Interested in any feedback especially about these I-131 spikes over the last three years. http://agreenroad.blogspot.com/2013/12/radioactive-rain-falling-downwind-of.html

    Arizonan, you may wish to look at the following and check out the radioactive waste discharged into the ocean:
    http://en.wikipedia.org/wiki/ocean

    The following comes from the above wikipedia link:

    The countries involved — listed in order of total contributions measured in TBq (TBq=1012 Becquerel) — were the USSR, the UK, Switzerland, the US, Belgium, France, the Netherlands, Japan, Sweden, Russia, New Zealand, Germany, Italy and South Korea. Together, they dumped a total of 85,100 TBq (85.1x1015Bq) of radioactive waste at over 100 ocean sites, as measured in initial radioactivity at the time of dump.

    For comparison:
    magnitude of radiation

    Global fallout of nuclear weapon tests — 2,566,087x1015Bq.[4]
    1986 Chernobyl disaster total release — 12,060x1015Bq.[5]
    2011 Fukushima Daiichi nuclear disaster, estimated total aerial release — 11,346x1015Bq.[6]
    Fukishima Daiichi nuclear plant cooling water dumped (leaked) to the sea — TEPCO estimate 4.7x1015Bq, Japanese Nuclear Safety Commission estimate 15x1015Bq,[7] French Nuclear Safety Committee estimate 27x1015Bq.[8]
    Naturally occurring Potassium 40 in all oceans — 14,000,000x1015Bq.[9]
    One container (net 400kg) of vitrified high-level radioactive waste has an average radioactivity of 4x1015Bq (Max 45x1015Bq).
    However, I do wonder where the US was storing their waste; I would have thought they would have had a similar amount to Britain and possibly the Soviet Union.

    Haven't posted in a while, been out and about. Surprised at a test result in Mexico. Using my Inspector, had readings of 10 min averages last week in the 80 to 105 range with my alarm alerting (set at 100) several times an hour (max I saw was 142 CPM). Had to turn it off as it woke me so often. Was receiving these reading in the Lake Chapala and Guadalajara areas. Higher than last in CA. Could be the general geology as well, have to do a bit of research. Anybody Know?

    We got readings like like, in the 100 CPM range, a meter above the ground at "reclaimed" uranium tailings locations in AZ. PRM9000.

    High radon gives N. AZ normal background of around 50 CPM.

    Lake Chapala is also high in elevation, and natural background radiation levels increase with altitude.

      Thanks Arizonan, also tested a meter above ground with the above results. Not as concerned about the spikes as I am as the background, out of 10 ten min surveys over 3 days the avg of those were 98 CPM so could be the rainy season and it is about the same altitude as Reno NV which has been just below 50 CPM overall. Will compare it to the next time I go down and see if there is a change. Rained two of nights before the survey. We keep posting so others may incorporate that into their data base as well. Not that I think there is any place any longer that is safe, this was better than guessing. Hug the ones you love!

      * Preserve a sample of that radioactive kiwi. Others will surely want to check it if/when you report your results.

      * You want to document well –perhaps in a traditional, bound notebook with numbered and dated-time noted pages/entries. This is serious business now.

    > http://radviews.com/map/

    It costs nothing, registration is easy, there are departmentalized forums, and the general public can see your graph (which is automatically generated per your postings, along with a computed standard deviation figure).

    For RadView's map, I think it's best to convert your CPM averages to (falsely assumed Cs-137) uSv/hr equivalents. (0.10uSv/hr for LND-7317 at 35cpm; LND-712 at 10cpm, M4011 at 16cpm, SBM-20 at 15cpm.)

      My low sensitivity gmc-200/m4011gm GC continues to record twice daily 60' averages of 21-23 CPM for desert cities CA, up only slightly from the Ap-My-Jn 60' averages of 19 CPM. Contrary to my belief that measureable 'radiation weather' will soon or eventually be coming here, and to the left coast in general, the 60' bar counts, or weekly totals, don't yet reveal any recurring, higher concentration 'waves' longer than 6-7', although EVERY 60' count records at least one momentary ALARM LEVEL reading, now set at 38 CPM, or twice the 9 month average of 19 CPM I have been recording, with some alarm readings to 45 CPM.

      I continue to trust that the M4011 and the GQ software readings will indicate any significant, recent, permanent, rise in background levels that would indicate the need for increased protection methods, or worse, evacuating to a safer region.

    Does anyone know about the charts on netc.com? The site has both EPA Beta and Gamma readings. My question is are those readings in 5 min., 10 min., or hour counts or longer periods in time counts? Thanks for any response…

    Thanks Craig for the links and I certainly read them all and they have an hourly count, but the question still remains- Does the EPA run a minute average count for an hour and report that or do they only use the present minute to state that hourly count?
    I fully understand Netc and their reporting methods and have paid access to the charts and find them very valuable, but trying to co-ordinate the Inspector Alert to EPA readings is what I'm trying to determine. And I believe I have found the answer, but need it confirmed by the EPA counts. Such as the following:

    Yesterday I was in Madison, WI and previously had noticed high readings there, so I wanted to see what my Inspector Alert recorded.
    My readings on GC no rain, somewhat cloudy about 72 degrees.
    Aug. 17, 2014 at 00:05 AM – 10 minute count 320 inside car being held gingerly from the top with windows and door open.
    According to netc record of EPA count.
    EPA Beta count Aug. 17 2014 6:33 AM……222
    EPA Gamma count Aug. 17, 2014 6:34 AM….174
    The EPA is adjusted from UT to local time CST. Whether you use 5 or 6 hours for the adjustment on the EPA- things are not adding up- thus my question on the EPA method in their readings.
    Or do the EPA have a special formula to combine the Beta and Gamma into in their total Gamma counts?

    There is no reason the top of the line Inspector Alert reading cannot be compared to EPA readings on a hourly basis- give or take a consecutive + or – 5,10 or 15% on an absolute scale. And everyone should be able to take their GC from city to city and know the EPA count through converting the Inspector data without consulting the EPA bank. For that matter all GCs should be able to do this with their respective data.
    Considering all GCs are tested with the same radioactive materials…and basically pickup everything on a total scale…

    • * In my last post, "PM" was supposed to be "CPM".

      It _appears_ that RadNet counts for an hour (per each energy channel), then divides the total by 60 to get the average CPM. (I don't think they explicitly state that, and I wouldn't put it past them to report the current CPM on the hour.)

      * There's good reason why your Inspector's CPMs (or even the trends of its excursions) will seldom track RadNet CPMs.

      ~ Your Inspector is counting (say) 2% of three (open-ended, MeV-wise) gamma or gamma-like components: the "NORM" distributed in the ground and buildings of your immediate surroundings; a base noise component (which several of us are currently investigating, but it's starting to look like cosmogenic muons/secondaries); plus any fallout accumulations on the ground and other area surfaces –natural and artificial.

      IMO: what's drifting by with the wind barely registers –until you concentrate and bring it near to your Geiger counter with a wipe or an air filter.

      RadNet's sensors are counting near 100% of the above components (in the lower MeV range) –plus the major component: an air filter concentration of whatever happens to be blowing past in the fickle wind.

      ~ NETC's CPMs are only for RadNet's #5 energy range, while your Inspector's energy sensitivity is open-ended.

      * In brief: a RadNet station tells us what's been passing by, while a private monitoring station gives us the gamma total of what came and what stuck).

  • The more sensitive the detector, the more radiation it picks up, so the higher the readings.

    EPA has very sensitive, high quality equipment

    FYI – Today my outside radiation station's 24/7 readings off my HEPA geiger station have been higher than normal. As a result, all our kids have not been allowed to play outside.

    Thanks for info Craig, Dr., and WW. Craig you mentioned the following comment on Aug. 16:

    My question what would the Inspector Alert use as a converting figure…and thanks…


    Report comment

    • The Inspector models I'm aware of use an LND-7317 G-M tube, which have a rated Cs-137 sensitivity of about 3500cpm in a 1000uR/hr gamma field. Everyone assumes that a typical field of background radiation (just about all gamma, with the Geiger counter a meter/40" above the ground) –is similar enough in nature to simply use that Cs-137 sensitivity for the conversion.

      Consequently, divide your time averaged CPM by 3.5 to get American uR/hr, and divide by 350 to get Euro-Asian uSv/hr.

    FYI – Currently I have high readings on my outside HEPA radiation station in South Beloit Illinois, seen on NETC.com and St. Charles Illinois also has high readings near mine. Both stations are private stations, both run off NETC.com but the operators are independent of each other. The equipment being used by both stations are similar, the and therefore it is ok to compare the readings with each other. Recently my anti-virus program flagged a free picture hosting site I tried to use so sorry, but I do not have a picture link to share herein. You can view the free readings of both stations from the public map at NETC.com

    Interesting site I discovered. I had not heard of before, but I am seeing that it is a monitoring network based on GPS/GMC with a rather cool detector that is built from a kit. Uses a high sensitivity mica type disc sensor. The map is coded in colors so it is easy to see the hot spots. Would be nice to have a set-up like that here. Doing some more exploring on this.

    Thanks for the link. Very smart indeed. I would like to build one but the cost can get out of control if you break something. But I like the idea of roaming sensors, however. The idea that one area could be hot and then a mile down the road average background, flagged if they remain hot for a period of time making it more urgent to explore the causes. Add the watercolor mapping would provide a lot of information in terms of how the weather would shape hot and cold zones. Planning a trip? Don't drive thru this area! A lot of potential I think. I would prefer both the stationary and mobile would be better than just either one. Of course this would be mute if the govt would just honestly handle it like they are paid to do.

    Thanks Craig for info. WWJD, I have been watching your site for awhile on netc and have indeed noticed your CPMs higher along with St. Charles. Also note that Milwaukee have been definitely rising since about June of 2014. Last summer Milw. use to have an average of 112. Now it is averaging higher. Could be the jet stream or ???

    Ok, now the real question- Does anyone know of a good lab that will not fudge the GC CPMS rate,which I could have set my GC in the future? Also has anyone ever tested a lab by sending a Inspector GC in and the following week have a relative send an I)dentical Inspector GC in, then compared the two for reading on both to see if they are identical? The reason I asked this question is because of sending in an air filter that test 65 in a 31 BG, which was used thru the harvest season for 6 months. Then I take an filter and read with my GC inspector and get over I think it was 3389 (total counts for 10 min. 33893) in a 41 BG which was used for 6 months thru the planting season. I personally think the lab fudged those numbers and of course they test for free but someone is paying them to stay in business- I think you kind of get the idea that's why I'm asking about a reputable lab doing the GC. Thanks for any help.

      Checkmate,
      I dont, but I am sure there some. I think the readings are suspicious if you know what I mean. I dont know what methodology u used, but if u try to attenuate the source you may find several different energy levels. I hope u saved them but if not next time use paper, foil and a little thicker aluminum until the detector registers close to background. I have experimented with containers like cans and various other steel vessels with varying success so just improvise. The important thing is to establish a baseline in the environment u test in.. There are methods requiring vastly more expensive equipment, but just to determine a ballpark energy the one I desribed should be adequate. Essentially having a Alpha and Beta source with the numbers you report is problematic. Best of luck and do post your findings here, please.

  • * I'm posting "off-topic" because we're coming up on the 2 month anniversary of our Alternative Energy forum becoming quite dysfunctional. That is a pity since, as Buckminster Fuller put it: "You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete" (which isn't hard to do at all in the case of nuclear power plants).
