Natural background radiation comes from two primary sources: cosmic radiation and terrestrial sources. The worldwide average background dose for a human being is about 2.4 millisievert (mSv) per year. This exposure is mostly from cosmic radiation and natural radionuclide in the environment. This is far greater than human-caused background radiation exposure, which in the year 2000 amounted to an average of about 5 μSv per year from historical nuclear weapons testing, nuclear power accidents and nuclear industry operation combined, and is greater than the average exposure from medical tests, which ranges from 0.04 to 1 mSv per year. Older coal-fired power plants without effective fly ash capture are one of the largest sources of human-caused background radiation exposure.
If you are speaking of the "old" yellow Civil Defense units, you are mistaken. They work excellent if calibrated and they can be sent to an outfit that does those calibrations.

These wacko's spouting on about abiotic oil have some serious disappointments coming their way hahaha. There is no free lunch people. There is no free ride.
