Handy List of USA, Japan, (and others) Radiation monitoring sites.

I wanted to put together a handy list of internet sites which claim to be monitoring radiation levels in the US.

I know that many of us do not really trust the government readings, but at least we can see some of the information to try and make informed choices.

Also, we can monitor our own area without waiting to a news agency to pick up a high level of something. We can also specifically monitor our individual States for levels in air, precipitation, and milk.

The following is what I came up with. Please feel free to post any additions. People cannot make informed decisions without accurate information.

This is an interactive map from the EPA showing the beta gross count rate which measures the radiation from all radionuclides that emit beta particles:

So far the levels seem to be stable or dropping off a bit. but there seem to be some exceptions to that rule. For instance the beta gross count, seems to be a slight up tick in San Bernardino Cali. [link to www.epa.gov]

Also Riverside Cali: [link to www.epa.gov]


There are also things that I cannot explain, where things seem to be elevated BEFORE March 11, so these would not be the Japan quake.

For Example:
Pierre SD:

Rapid City SD:

This site also gives the EPA State by State analysis of air filters, precipitation, milk, and drinking water levels of: I 131, I 132, I 133 and Cesium 134, 136, 137, Cobalt 60 Te 129, 132 (scroll to the right)

Here is an interesting graph of the radioactive monitoring from the University of Washington Physics department:It shows levels of cesium as well, which has a half life of around 30 years.

Here is from "Air Monitoring at UNLV" (University of Las Vegas)

Here is the EPA site (FWIW anyway)
