On 25 May 2012, I posted how the public display on the Big Lost River IEMP station, in eastern Idaho, was not working.  Now it is, and it’s showing 10 more micro Roentgens per hour than what is being posted on the www.idahoop.org website.

Big Lost River IEMP Gamma display, 16 June 2012

On 16 June 2012, the display was showing between 24 and 27 μR/h!  I watched for ten minutes and it never went lower than 24 μR/h.  I checked the website and discovered that it was reporting gamma levels of 15.2 μR/h.

Why the big difference?

For perspective, 9.8 μR/h is considered “less than typical”.  The ghost city of Pripyat, which was contaminated by Chernobyl in the 1980s, is still showing gamma levels as high as 66 μR/h!

The Big Lost River IEMP is located in an area of eastern Idaho that has been used for nuclear experiments ever since World War 2.  Are these high(?) gamma levels the result of decades of experiments (still ongoing right now), or is it because of the ongoing disaster at Fukushima Daiichi in Japan?
