EnviroReporter.com has in-depth databases of information from Spring 2011 to the present including Special Radiation Station Testing along with food and drink radiation testing from over a dozen nations in Radiation Food Lab.
We have been measuring in CPM because it is easier for most people to see the difference in radiation levels. The baseline external radiation background we’ve established for this location is 42 to 46 CPM which equals 0.012 to 0.013 mR/hr.
