USA Radioactive Rain: A snapshot in time and space: A couple EPA Radnet Gamma graphs with Rain data (Spring 2011 versus Summer 2013).

[Nuance-adding disclaimer: Added Jan 8, 2014:  Until lab tests are performed on rain samples at the time of radiation spikes, no statement about the cause of the observed elevated radiation measurements can be made scientifically: neither that it’s natural, nor that it’s from Fukushima.  It requires lab tests.  Blogpost otherwise left unchanged.  DISCLAIMER

Presenting EPA and weather data from these US locations:

Selection of sites I checked radiation and precipitation data for.

Selection of sites I checked radiation and precipitation data for.  See below for examples and data sources.

The selection of cities (see map above) was based on having lived there, passed through, been to, or having friends near these locations.  Locations not shown here may have more pronounced radiation-precipitation correlations.  You can check this yourself with the data links provided.  As I was putting this together, I saw how time-consuming putting this together is, and as I became rather bored with it, the presented is not complete for all locations.  There’s a couple notes and comments throughout and at the end.  I figured it’s better to post as-is than to leave it sitting in draft for the weeks to come…

In this blogpost a presentation of data showing:

  • EPA Radnet Spring 2011; showing gamma radiation ranges for the 3 months including the March 11, 2011 Great Tohoku Japan quake, after which radioactive particles blew accross the Northern Hemisphere, noticeable in spikes on the monitors; and the same gamma radiation ranges for Summer 2013;  Data from the US Environmental Protection Agency’s RADNET.    It would have been ideal to include the ‘Gross Beta’ measurements for both times as well, but the EPA makes that unbelievably time-consuming and, a staple of EPA land… data is often missing.  Fluctuations in gamma rays DO NOT imply fallout from Fukushima, but CAN be caused by that.  Cosmic rays from outer space as well as local soil dust & radon can also cause minor spikes.  (I’m anti alarmism, and simply cannot buy  into some narratives…).  However, it appears radioactive fallout is continuing to reach the US, and in some locations more so than in 2011.
  • 3 Months of (one year of) local precipitation data, digitally stretched to be visually match the above Radnet timelines for easy comparison for the first 4 locations.  That being a bit too time-consuming, I switched to just placing a black square around the corresponding periods on the year precipitation graphs.  Data from Weathersparks, both for Spring 2011 and Summer 2013.

Clicking on the image will take you to the source of the data and/or the most recent data:

  • Anchorage, Alaska
    • EPA Radnet Spring 2011 – Anchorage, Alaska:

      PS: In early May 2011, the EPA returned to ‘routine’, deeming all “back to normal,” quitting all additional monitoring.  If the gamma spikes seen after are any indication, they quit monitoring more thoroughly way too early.

  • EPA Radnet Summer 2013 – Anchorage, Alaska:

    Note: During most of the August 2013 rains (below), the Anchorage Radnet monitor (above) was simply turned off.  While the June 1 rain showed a little gamma radiation spike, the July 1 rain didn’t.  The September correlated spikes are visible, but not as pronounced as in some other places much further east.

—–[ To save myself time, after this the images are unadjusted in size, with corresponding rain periods simply marked by a black square.  Look closely.]—–

[added 9/23/2013]: Beta monitoring appears to be currently turned off in much of the Pacific Northwest, spitting out only all-“0.0000” values for Seattle, Richland, Portland, Tacoma,… Check around yourself with the EPA Query Interface.  Beta emitters include: tritium, cobalt-60 strontium-90, technetium-99, iodine-129 and Iodine-131, as well as Cesium-137.

  • Eureka/Arcata, California
    • EPA Radnet Spring 2011, Eureka, California:

      Fallout disturbances were relatively minor and limited to mostly March and April 2011… until mid-August 2013, even without rain… (see further below)

  • Los Angeles, California
    • EPA Radnet Spring 2011, Los Angeles, Californiahttp://www.epa.gov/japan2011/rert/radnet-losangeles-bg.html

NOTE: In many cases I’ve wanted to graph the Gross Beta, which the EPA now hides in its database, accessible through its often-crashing and ridiculously time-consuming https://cdxnode64.epa.gov/radnet-public/query.do  See the Atlanta, GA graph below for an example]

  • EPA Radnet Summer 2013, Oklahoma City, Oklahoma:

Now, just to mix it up, here’s Spring 2011’s Gross Beta data for Atlanta, Georgia, on which I indicated the two days the EPA chose to analyze the rain there (see data here).  On April 15, they found 17 pCi/l of short-lived I-131 and the rest was “ND” (none detected), which translates to 0.629 Bq / l, less than a Becquerel per liter).

Note also how the detection was turned off around May 30 and June 14I could think of a lot more days to test the rain…  This just to illustrate how little data they even bothered to collect when they were not “on routine schedule” (to which they returned May 3, 2011):

  • CONCLUSION / COMMENTS

Just like the leaking of radioactive particles into air and water never stopped in Japan, the raining down and blowing over of radioactive particles continues to hit North America.  All estimates based on 2011 measurements, such as those included in my blogpost “Fallout Maps for the United States” must be seen as extremely inadequate, underestimating the actual fallout deposition.   In some locations, summer 2013 may have seen more radioactive fallout raining down than in spring 2011.

The fact that Gross Beta is no longer graphed as part of the presentation, but hidden in the time-consuming (and unusually ‘proxy error’ prone…) “https://cdxnode64.epa.gov/radnet-public/query.do“, as well as the observation that monitors are occasionally turned off during precipitation events that may have otherwise shown as radiation spikes, as well as the extreme lack of sampling and testing of samples, and the ridiculously user-unfriendly interface (with 5 different routes to find very small amounts of data), the fact that the inadequate “network” has not been improved upon since March 2011, and the continued blanket statements about the most likely accumulating exposure to low-level radioactive particles being “of no public concern” (contrary to scientific studies), has left me with the impression that the EPA (and FDA in regards to food) do not hold the public’s best interest at heart, but are essentially covering up the extend of this ongoing worst nuclear disaster in history, very much as if they take orders from the pro-nuclear establishment.
