      Hi Vital,
      You located in Australia, right? Would you post some food readings of fish and vegetable if possible? Thank you for your posted information and links! If you anyone has information about California, I am extremely interested in all current readings. The radiation network doesn't have a bay area monitor and the official monitor in San Jose, CA has been turned off since Fukushima 2011. The current Gov page http://www.cdph.ca.gov/Pages/RadiationFAQS2011.aspx doesn't have updated info.

        "The Food Lab" tests local grown produce 24/7. So far nothing grown locally has been found with fallout contamination. There is no way every food item here has been tested. At best this is a sample of what is grown here.

        Some dairy has been tested but not much fish or meat has been tested at my location. Most people who are aware have been avoiding these foods.

        @enoughalready45;THANKS!!~ I've been keeping track of the spikes which are evident here during almost every precipitation event since I'd gotten a new,Russian-made,pancake-tubed Geiger Counter/Airborne Pollution Monitor(MEPA AQ-22)-but have probs figuring out what measurement mode it's in since an accidental reset that found the display & menu stuck in Russian language/Cyrillic-character mode & lack of USB driver SW compatible for Windows 7 while I'm searching for a source for the two 9volt,paper-cased industrial-type batteries my old,trusty,British-mfg. analog GM with ext. probe(?). I'm guessing the AQ-22(advertised as having the same high-end pancake tube as the blue Radex units)-is probably displaying in "uRemHr" mode as it reads "7" during the best conditions-but usually hovers between 9-12 uRemHr(?) with recent spikes hitting 14-27 when "something's up"(?)!,and air pollutant particulate matter readings(ppm or "parts per million") are ALWAYS well above the limits which cause concern for human health and I have to MUTE the audible alarm to keep the device from being smashed by angry family members trying to sleep & who don't need any devices to alert to the presence of foul air thanks to "Ingredion's"(formerly Corn Products Corporation-CPC)blowing the stankiest funky stuff from their many vent stacks along with a host of other grody industrial facilities that have the EPA out here at least once a week(!)-(to get "paid off"?!)~"60501" SUCKS!!~ :( ~**

          It may be worth mentioning that there was an article posted on one of the civilian radiation monitoring networks blog that described an anomaly that wasn't fully understood regarding extremely elevating readings when GM monitors were placed in sealed plastic bags(?) as opposed to letting the air circulate around the GM tube as it would be operating in a fixed or indoor location and the only explanations were shaky at best since the high radiation findings inside the sealed baggie theoretically should've been higher when the GM-tube mica window was exposed & getting hit by the hot particles swirling through the open air!(??) I would also assume that the baggie would effectively block Alpha detection that seems to be prevalent in post-3/11/11 rain/snowfall analysis that the same websites alleged were extremely high,but also very short-lived Alpha detections thought to be Radon(?)washout??!! It's a bit confusing trying to figure out what's what anymore?!!

      Who knows if that's what caused the readings, but it's had its share of problems.

      + in april 2011, the 3 reactors scrammed due to loss of power because of a tornado

    Yesterday set a day average detection record for this location. It was 0.213 uSv/hr, or 113% above average. The highest day average ever recorded here!

    This morning I am also getting multiple Geiger counter alarms. It is set to alarm at 0.50 uSv/hr.

    Spot peak observations and alerts are helpful, but not good enough to fully understand what is happening in your local area. Day average background increases can mean you are cumulatively getting a far bigger radiation dose, than from a short term peak detection would indicate.

    A day average is the average of all the 24 hours logged data. This is a better representation of your radiation exposure. Here local background is logged every 60 seconds, and at the end of the day the 24 hour average is worked out. That is what the chart above represents. Those of you who are interested in doing this, can find templates, and information here.

    There are three main possibilities why we are getting this high detections in Australia, and New Zealand.

    1. Fukushima contamination.

    2. Australian contamination from local Uranium mines.

    3. A combination of the two above.

    We have conducted scintillator testing here of the rain washout from the recent rain event, that caused a lot of flooding here, plus these very high detections.

    Besides the usual Radon washout decay daughters, testing is showing traces of Uranium, plus other isotopes in the samples. We are still analyzing the test results, and will post a more detailed report with test charts once complete.

    These test results have been distributed to a number of people for analyses, and discussion.

    Here is a Twitter of a 2012 monthly average radiation level chart for Fukushima city, showing the increasing radiation levels there.

    http://twitter.com/tadagonpapa/status/279540046502170624/photo/1

    Interestingly, it mirrors the monthly chart recorded at my location in the Southern Hemisphere. Obviously at my location it is at a lot lower levels, but both chart curves are very closely tacking each other.

    This is last year 2012 monthly average chart at my location.

    http://sccc.org.au/wp-content/uploads/2012/09/Caloundra-monthly-average-background-radiation-levels-for-2012.jpg

    This is January 2013 month average. It is 52% above the pre Fukushima monthly average. The highest monthly average I have ever recorded here. If I am correct, and it is tracking, then there have been large releases of Radiation at Fukushima in January and December 2012, and January 2013.

    It would seem if something major has happened at Fukushima, I appear to detect it using this very detailed data collection process.

    This is something different. And I apologize if my request is on the wrong forum. My favorite ink pen, "Uniball Signo" is made in Japan. Could anyone with a gieger counter check those for radiation? I'm using one just about 18 hours a day and if it's got radiation, that's not good. I get them at WalMart and have maybe 50 or so since the 3/11 catastrophe. This might help someone else, as well. It's a popular pen in northeast Missouri.

    Traces of U-235, and mystery Isotope found in local rain water test, on the Australian east coast.

    Around 880 grams of activated charcoal was placed in the down pipe from a tin roof, just before the major flooding weather event, passed over the area in late January 2013.

    A reference test chart of the charcoal was made, so it could be compare with the down pipe charcoal capture test. The activated charcoal came from China, and already had some isotope contamination. It was used anyway.

    After this weather event had passed, the down pipe charcoal was then dried in the Sun. The charts here are a comparison between the reference, and the down pipe test.

    As you can see the charcoal filter did capture some significant isotope markers.

    http://sccc.org.au/wp-content/uploads/2013/02/Down-pipe-rain-test-three-280113-to-030213-TV42-with-text.jpg

    Remember a lot of water went through this filter to get these results, so in overall terms, they are small detections. I think this proves we are getting fallout, but not what we expected.

    U-238 produces a small amount of gamma at 50 (0.06%) & 114 (0.01%) keV and X-rays at 16 & 12 Kev. U-235 puts out a lots more gamma at 186 (57%), 144 (11%) and 163 (5%) kev and X-rays at 89 and 93 keV.

    This is the third test sample tested here, that found the signature of the fallout isotope/isotopes, at around 492 keV.

    1. It was detected in a local soil sample last year, at my location.

    2. It was detected in the activated charcoal down pipe capture test. (See previous post report above.)

    3. Detected in the cloth rain swabs.

      Have you performed test-measurements over time on the samples? Nailing down the half-life would go long way towards identifying the isotope, as it is the reports make it hard to even guess how long after collection the measurements were done.

      One gamma-line source not yet mentioned is http://atom.kaeri.re.kr/cgi-bin/readgam?xmin=490.00&xmax=494.00&h=2.00&i=50&l=50 which is handy as it allows limiting by half-life and intensity.

      The local radiation monitoring authority here frequently detects I-131, Mn-54 and Co-60 mostly from radiomedicine/industrial measuring accidents around europe. There's been occassional detection of Fe-59, Co-58, Tc-99M and Am-241. I assume other isotopes must be out there too, but for some reason they are not reported ("Naturally occurring" and such). I suppose one could check the gamma lines for those common isotopes.

      Mystery isotope in the above test chart may be Beryllium Be-7 at 477 keV.

      "Can you try this sample again with a beta shield?" PavewayIII suggestion

      I put a extra Aluminum beta shield directly in front of the Scintillator crystal, with these rain swabs behind it.

      This shifted the gamma peak to around 477 keV, which is the marker for Beryllium.

      Beryllium puts out 10% gamma to around 90% beta. Beryllium beta energies are 11% at 384 keV, and 89% at 862 keV. There must be an interaction of these beta energy's with the scintillator crystal, that was creating the slight gamma peak shift to around 490 keV. Berylllium also has a 53 day half life.

      Fukushima Corium, plus Liquid Nitrogen Injections, produces Beryllium Be-7 from what I have been reading. It can also be created by a solar coronal mass ejection hitting the earth's atmosphere.

    Cinnamon isotope Detection (05/02/2013)

    An 80 gram packet of Cinnamon imported from India, that was purchased in Australia, was found to have traces of Uranium isotope decay daughters in it. This is the second sample of Cinnamon that we have detected with isotope contamination. The other sample purchased last year was imported from Europe, and only had trace amounts of a single isotope.

    This packet of imported Cinnamon from India has multiple isotope peak signatures in it. This is probably from soil contamination during harvesting, processing, or root uptake. K40 is radioactive Potassium which is in every living thing, Pb-214 is radioactive lead, Bi-214 is radioactive Bismuth, and Ra-226 is Radium. We all ingest a small amount of Uranium every year, because it is naturally in soils in small amounts, plus some plants absorb it through their roots.

      Thank you PattyB! That was a lot of work. Looks like Salt Lake City's pollution was holding a fair amount of radiation. And it looks like Anchorage, Alaska is the best place to live. Dallas is not looking good.

      Question: What does it mean when it says, for example, "Gamma Energy Range 4"? Does it mean that there are different types of gamma particles and some don't have as far a range as others? Sometimes I'll see a red line go up (like in Texas, before A.Higgins site went down) in that gamma chart or a pink line go crazy. Thanks ahead of time.

      To insulate it from humidity. Contamination can also occur over a period of time and if you want to use your GC for sensitive food or ambient air reading, that contamination may be significant. Especially if you have a lead box that you want to use for accurate measurements of food,etc..Can you imagine using a GC in a hot environment, then trying to use it later in your home or office?

    I had mine for ages in a plastic bag and it didn't make any difference to readings. I don't anymore cause it's a pain when I have to change batteries and also it's harder to see.

    I'd use a bag if it was raining however mind you.

    I've heard about it can build up this and that but I haven't seen anything on the group I'm on to suggest it's actually true.

    Up to you I guess. :)

      I am quite interested in the build up of "this and that" that can occur as I think it may be happening to one of my GC's….

        If you bag it when the humidity is elevated, your Geiger counter will be fine for a while, as long as the temperature doesn't drop. If it does, then you can get condensation in the bag. This could potentially damage the the circuitry in the long term.

        If you placed a bag of silica gel in the bag to absorb moisture, this could prevent this dynamic from occurring.

        I have heard the theory of plastic bag radon build up causing Geiger counter false alarms. I have seen no evidence of this. I have tested rain swabs in sealed plastic bags, and left them for periods of time for retesting with a scintillator, and have not detected any increase in Radon daughter activity.

        In my opinion, this is more likely to be caused by condensation in the bag.

          I have read here once before that there is some kind of electro-static build up that can cause false readings, even if the humidity in the bag is quite low. I would like to find out more about this…

            That is a possibility because Geiger high voltage circuit at the centre, and the plastic on the out side could create a capacitance.

            A large voltage difference between the outer plastic bag, and the high voltage Geiger counter circuit could build to a point where it could discharge. Particularly if the plastic bag built up its own opposite polarity high voltage electrostatic charge, from the environment it was in. The potential difference would be even greater.

    Here is the simple roof down pipe collection filter design I used to capture the fallout isotopes discussed in the post above.

    Down pipe filter design

    http://sccc.org.au/wp-content/uploads/2013/02/Roof-down-pipe-filter.jpg

    There is approximately 880 grams of activated charcoal in the gray pipe section. When a collection test is finished the charcoal is removed and warmed in the sun to dry it out. It is then emptied into a large marinelli beaker, and placed in the scintillator test chamber.

    If you have better equipment to test with than a Geiger counter, I think this method is a much better detection system for detecting trace amounts of fallout. The paper swab system is a quick, and effective collection system, for a Geiger counter test.

      The side pipe is to release pressure if the flow rate gets to much, or the particulate filter starts to get blocked.

      Inserting filter

      http://sccc.org.au/wp-content/uploads/2013/02/inserting-filter.jpg

      The side pipe is usually angled at a much steeper than is shown in this picture. This is to improve the flow rate through the charcoal.

      During a rain event it maybe necessary to remove the filter, and replace it with a new one. It can get blocked from the first down flows off the roof, if it hasn't rained in a while. You can do this easily and quickly by putting your hand in through the side pipe and removing the old filter, and replacing it with a new one.

      Always use disposable surgical gloves when handling a rain swab, charcoal or filter, when using either testing system. Also keep your hands away from your face, and wash your hands well afterwards. You have no idea what you may have captured!

    High levels of cesium detected in fish off Chiba

    Fish caught in waters off Choshi City in Chiba Prefecture have been found to contain radioactive cesium above the government safety limit.

    Choshi is nearly 200 kilometers south of the crippled Fukushima Daiichi nuclear power plant.

    Chiba Prefecture says it found 130 becquerels of cesium per kilogram in Japanese sea bass caught about 10 kilometers off Choshi on Thursday of last week. The acceptable limit is 100 becquerels.

    Contamination proof of Mutton Birds, American Helicopters, Food from Japan, and people.

    Assessment of the impact on Australia from the Fukushima Dai-ichi nuclear power plant accident Julia Carpenter and Rick Tinker.

    http://www.arpansa.gov.au/pubs/technicalreports/tr162.pdf

    Some extracts.

    1. Food from Japan page 22.

    ""Health impacts from imported foods

    Of the food imported from Japan into Australia (which represents less than 1% of the food imported
    into Australia), only 7% tested had detectable amounts of 134Cs or 137Cs, and all tested well below the Codex guideline level of 1000 Bq/kg.

    As an example, for an imported food contaminated with 1000 Bq/kg of 137Cs and assuming 55 kg of that food was consumed by an adult over one year, then a dose of 0.7 mSv can be attributed.

    The health risk associated with this annual dose is negligible. It is highly unlikely that an individual would consume 55 kg of contaminated food imported from Japan. In addition, the food testing undertaken by ARPANSA suggests that foods imported from Japan are not contaminated at levels comparable to the Codex guideline levels. For consumption of a smaller amount of contaminated food (e.g. 0.55 kg), the estimated dose is 0.007 mSv.

    These results indicate that the risk to the health of Australian consumers is negligible."

      2. Family living in Fukushima, page 32

      "The levels of caesium measured in urine across all family members were similar ranging from 0.2 to 0.5 Bq/L for 137Cs and 0.1 to 0.4 Bq/L for 134Cs. This indicates that a chronic intake (daily over 150
      days) of low levels of radioactive material has likely occurred. An acute exposure, for example in the first week after the accident, would result in significantly less caesium in urine of children compared to an adult, assuming all members of the family were equally exposed."

      3. Vehicles and Military aircraft including American helicopters, page 28

      They appear to be using measurements of square centimeters cm2 instead of per square meter m2, so multiply by 10,000 to get the square meter amount.

      Analysis of the wipe samples for radionuclide content confirmed the presence of Cs134 and Cs137 on the aircraft surfaces at very low levels ranging from less than detectable to 0.1 Bq/cm2 (Table 5.1). The ratio of 137Cs to 134Cs ranged from 1.2 to 1.6."

      4. Tasmanian mutton Birds, page 36

      "Tasmanian mutton bird testing results are in the PDF I just sent starting at page 36.

      Levels of 137Cs and 134Cs were less than 0.19 Bq/kg, the detection limit for a 24 hour count. Results are shown in Table 7.1."

    The EPA's Radiation Network beta counts page lists all zeros for Fort Wayne, IN, today and all zeros for Indianapolis for the past several days. It also lists unusually low numbers for Toledo, OH, today (and the Chicago cities pretty much always list zeros or simply no data). What is going on with the Radiation Network?

    The local background here has increased, from 34% above background to 47% above in 24 hours. It has been fine with no rain during this period. the temperature has risen during that period, but not by a large amount. Solar activity has been quite. There has been a lot of moist tropical air flowing down our coast.

    Radiation levels throughout this month have been elevated, not as much as last month's record, but still way above the local background pre-Fukushima 4 year average.

    See the chart, a green bar means average to slightly elevated background levels, and yellow means it was 40% above the four year pre-Fukushima average of 0.10 uSv/hr.

    The other very small peaks showing in this chart could possibly be trace detections of other isotopes. At these small detections levels, they could also be created by a bit of random variation in counts in the background level over the time of the tests, showing up in the tests results.

    A lot of water flowed through this charcoal, in the down pipe, to get these detections.

    Read in this previous post how the down pipe filter was set up.

    I live in Branford, CT (USA) and readings tonight were between 8μSv/h to 20μSv/h. That's the upper east coast of the United States!

    I mean 8uSv/hr to 20uSv/hr!!! When I started taking readings they were .07uSv/hr it was like that for around an hour. I was getting ready to go inside when all of a sudden a strong breeze came by and the meter starting alarming, at first I thought there may be something wrong with the meter but after checking and recalibrateing it the readings were the same. So I spent an hour taking some more readings around where I live and still they were very high, every time time a breeze/wind came by the CPM's would rise significantly higher. So I drove around town taking readings and they were very high everywhere, it was also snowing and windy.

  • I've posted the graphs and such from EPA stations up here in the north east… and yet not many take what I been saying to heart… it's bad. Not as bad as CA places.. but still.. we have the older group of NPP all in a clump, and get the cumulative crap from a wide area of US funneled up here over us.

    Yes PattieB, it certainly is bad up here with all the nuke plants bundled together. Also being b*tch slapped by the jetstream and all the fallout it carries from Fuku and the rest of the nuke plants. Back in September I had a reading of 429CPM. This month alone I had readings of 187CPM on the 4th, 182CPM on the 16th, and multiple other high readings.

    Does anyone know whats going on in San Fran or Oakland, CA?? I just saw the reading on my 'rad app' and it said 199 as the count. Now on the auto update, they pulled it off the network. So I went to Radiationnetwork.com and it shows 88 count. Did something happen? Anyone live in the area and hear of anything? I wish I knew how to copy a page…but I am sorta computer illiterate.

        Blackcat systems shows 41 uR/hr around San Ramon area at 1120pm tonight. Maybe there is an industrial leak or does Livermore/Berkeley Labs have facilities in that area?

        Rad counts seem more elevated than usual, in the last few days, along the US West Coast on Blackcat but normal on RadiationNetwork. In North Bay area, I spotted what looked like a radiation monitoring helo, today and yesterday. They fly fairly low and cover a large area with a white round object visible and long horizontal 'sensor' of some sort. With recent eQ's in Honshu, I hope to see more helo surveys in near future and more rad b'slapping on the ground! Problem is, nothing is published about the survey findings, not yet anyway. The helo's are flying through milky white skies from all the non-regular looking aerosol trails spewed out behind white jets.

        On a blog, several people along Pacific NW, CA coast, and Bay Area are recently having problems with our dry weather and severe chapping/bleeding skin, maybe drought plus accumulating rads in water? Best to not jump to conclusions but it's likely our reservoirs are loaded with fallout. I've heard taking a hot shower for ten minutes is like drinking 8 glasses of same!

      If you don't mind answering, is your 'rad app' something that was offered but then removed – 'that' one? There seems to be a concerted effort by official agencies and independents to alter, remove, or otherwise dial down rad measurements, yet the radiation continues to fall out. It's like the Kevin Blanch T-shirt that says something like, 'Travel Fukushima – we're already there!' Truth is that people want to avoid ugly reality, here and in Japan. For instance, given all the people in San Jose, how many have called their EPA office to find out why there is a total absence of beta numbers on Radnet's public query? It figures that any rad measurement might be much higher in a different location, not far from a fixed monitor. Holding up a gloved mitt to catch rad isotopes in the air for an hour does not count as a distribution study. Radiation distributes unevenly so dangerous local hot spots are invisible except for individual monitoring on a regular basis. OTOH, might we see significant gamma baselines moving upward over time, especially with nonstop fallout and future, incoming rad water evaporation? My understanding was that a huge gamma burst occurs as part of the ongoing, natural decay of plutonium, a couple(?) of years after a large alpha radiation event. Please correct me, anytime- :)
