[ RadSafe ] Gamma background radiation at ground level

[McNaughton, Michael]

There is a similar system at Los Alamos: newnet.lanl.gov (without www). 

Regarding cosmic rays, I have studied the data during supernovas, solar flares, etc., and the most I have ever seen at ground level is an increase of about 0.5 micro-R per hour; the atmosphere is a good shield, even at an altitude of 7500 feet. 

Almost all the variations that we observe are caused by radon decay products (Bi-214 etc.) Sometimes, during a rain or snow storm, we observe an increase of as much as 10 micro-R per hour. We know it is caused by radon decay products because it decays with the expected combination of half lives.

"Dear Radsafers - Does anybody know where I can get day to day (or hourly) gamma background (cosmic) and/or neutron readings at ground level? A station near California, USA, would be ideal but I'll take anything. Thanks in advance, 
D. Felipe Gaitan, Ph.D."

The above link is to the Community Environmental Monitoring Program
by the DOE and Desert Research Institute here in Las Vegas. The instrumentation is
by Reuter Stokes with the basketball sized sensors (PIC).

There are other such programs out there too, including a grass roots network of
BlackCat Systems detectors. 


Good luck with your research
