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.
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.

Three robust High Efficiency Air Particle (HEPA) filter air-cleaning and negative ion generating machines have kept EnviroReporter.com‘s Radiation Station Santa Monica air clean and refreshing since the advent of the ongoing triple meltdowns in Fukushima Japan in 2011 as we wrote in Eat Me! that year. One of our machine removes “99.97% of as small as 0.3 microns contaminant particles like pet dander, mold, viruses, bacteria and pollen,” according to a review of the Honeywell 17000-S Air Purifier. “The HRF-AP1 pre-filter has Activated Carbon filter in it. This will both help adsorb VOCs, gases, odors and trap larger particles such as dust, lint, fibers, pet hair & fur.”
EnviroReporter.com‘s air cleaners ‘harvest’ much of the dust and debris that we test for radiation (by vacuuming it off first). The air cleaners also remove viruses like the Coronavirus (COVID-19) making them potentially very effective in rooms in buildings where air is circulated and shared. Aston An added benefit is that HEPA machines filter out the radiation we regularly test for and find, as shown below. This latest test finds the dust/debris sample testing at 230% of background, which is actually a decrease from the previous period’s testing. The following reading is below the California Highway Patrol’s limit of 3.0 times background before a substance is considered hazardous requiring HAZ-MAT protocols.
