Sometimes All Seems Normal… (Today’s 1.5 µSv/hr rain event seems “within normal variability range”: No EPA data gaps) + some links (Nuclear Cultists, Sr-90 at new record high, etc.)

Crestone, Colorado – July 18, 2015

66.3 CPM*

This past week this location has seen trace amounts of rain every day and some nice downpours sometimes in a local thunderstorm.  I’ve put my Geiger Counter on some windshield swipes just for the hell of it.  It’s been what I’d call “boring”:  all well below 1 µSv/hr.  (Except this afternoon…)

Rain over over 10 µSv/hr surely got my attention.  So much I sent a sample to a lab, thinking I could blow some high pitch whistle… but I think I (at least partially) misinterpreted the listed radioisotopes for ‘detected’.  Not as simple as that, I’m learning.  Same with the energy peaks flagged as unknown.  Most might stay that way (‘unknown’), and my attempts to identify them may have been merely a good waste of time on my part… ;-/     Well…, not a waste for me: I still learned a lot while searching.  And there may actually been some ‘detections’ in there that tell a story that needs to be heard.

Hence I invited folks more knowledgeable about radiochemistry to scrutinize the raw data and leave comments @:

Anyways, read my DICLAIMERI seek the truth.  But I don’t claim it.  I’m still looking at the data and wondering what means what precisely and why.  Some comments have been helpful under

Anyways… The natural background radiation here at 8,000 to 8,500 feet is between 0.2 and 0.3 µSv/hr most of the time (roughly 60 to 80 CPM).   Mostly from cosmic rays, with rocky soils (relatively rich in Uranium-235/238 and Thorium-232) contributing as well.

Most rain swipes this past week were in the 0.4 to 0.7 µSv/hr range on beta-window-contact with the rainwater-wet paper towel.   I call that, ‘Normal’.    At least for a mountainous region like this one.   I’m on the western slopes of the northern Sangre de Cristo range, a part of the Southern Rockies; right near the Great Sand Dunes National Park.    This is actually why I check when I don’t expect spikes at all: I want to know how high the natural fluctuation range might go in this mineral-rich region.  

When I detect highly radioactive rain, the graphs of the EPA Radnet tends to have major data gaps, and sometimes spikes.  When I don’t… they don’t.  Checking the nearest EPA Radnet radiation monitor, in Colorado Springs, some 100 miles to the northeast, and there’s practically no spikes nor data gaps this week, either.    Fitting with previous observations:

ColoradoSprings_Radnet_1week_preJuly18_2015DATA !–> For how to check these yourself, see my July 4, 2015 post,  How to scatter plot the EPA’s Radnet data.  They’ve fixed the lack of mentioning the location name on the graph, as obvious above.  Nice.

See various previous posts for data gap examples, including in Alaska… ;-/

Anyways…   The rain at 5:45 pm (Denver time, known as “Mountain Standard Time”, which is UTC-7) this late afternoon tested 1.5 µSv/hr.  Nothing like the whopping 10.2 µSv/hr seen on June 14th, but definitely elevated.   A CPM test after swiping was 427 CPM in the first 10 minutes,  423 CPM in the first 20 minutes.

The Nullschool jet stream wind data shows that wind is coming from the south. With a bit of an eastward movement in lower layers, it could come from the southwest.  And out on the other side of the Pacific, the jet stream is NOT blowing straight over Fukushima.  The southern end of the jet stream wouldn’t make it here either.  Just noting things:,38.59,512

Screenshot with my scribbles on it:

Nullscholl_July18_2015_2100 UTC_250hPa_SoColoIf Fukushima-Daiichi is continuing to spew radioisotopes into the air, I would expect these not to be detected right near the catastrophe site, but to rise to higher elevations quickly.

At present time, the only places I would “expect” fallout spikes, if there was a ground monitor there, would be over some parts of the Northern Pacific.   Wind Patterns are such that I don’t expect to see much on monitors over land today.

I find it mention-worthy that I’m not finding data gaps on monitors right now when I would not expect Fukushima-related spikes.    That’s all.


Note: In he coming months (“3 months till winter…” aka WINTER IS COMING‘), I’m busy during the week, so I have to limit my online time to the nights and weekends.   I’ll post more about my sample data when I can ánd when I have a better understanding of what I’m looking at.


  • Japan in the Grips of Nuclear Cultists…?

Something about members of a dangerous cult having found their way into Japan’s nuclear establishment and pro-war government…


This is a vein of investigation that ought to be explored further.  SOme of his writing can be found at:

“Mad Men, Fukushima and More Mad Men… Read More >>> April, 2015.

Fukushima! The Final Battlefield…you asked for the truth…but can you handle it?… Read More >>>  Jan 28, 2014.

Fukushima and the Minister of Human Extinction: Should we worry that the Minister responsible for decommissioning the destroyed Fukushima nuclear plant is a senior member of a Japanese doomsday cult?… Read More >>>   Dec 11, 2013.

The Cult Of Nuclear Fascism Has Arrived!… Read More >>>   Dec 6, 2013.”

Interesting (to me) that Garry’s writing on the topic took off right when I returned from Japan…  (See Nov 2013, A Visit to Fukushima, Cut Short. With PHOTOS and Reflections, etc.)

Screenshot of Gary Greenwood’s front page on the matter:

Some of what’s touched upon there corresponds well with archetypal dynamics descrived in my post (Sept 2013) “The Darkest Dance’ – Archetypal Dynamics of the Nuclear Era’.

  • Sr-90 on the rise…

Passing along this reported news:  Strontium-90 concentration in Pacific Ocean shore water reached new record AGAIN… 

!-> See Fukushima Diary, July 18, 2015, “Highest Strontium-90 density detected in seawater off Fukushima plant port / 1,500,000 Bq/m3

!-> For context, see also my (Sept 2014) post, Strontium-90 skyrocketing in Fukushima’s On-Site Groundwater. German meltdown model that predicted this suggests worst is yet to come.

* With Medcom Inspector Alert:  half hour average, @ 8,200 ft, in car front with front doors open, horizontal, beta-window downward, one-half of beta window exposed to air (sticking out over book).

    MVB, maybe these folks can answer your questions on the rain/lichen results:
    Thanks for sharing all of the beautiful photos and great analysis.
