EnviroReporter.com has in-depth databases of information from Spring 2011 to the present including Radiation Station Stats 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.
Over 10,000 multi-media radiation tests across America since 2011
Note that none of our readings at Radiation Station Santa Monica California [RSSMC] are impacted by radon progeny as we discuss in Beta Watch.
