meanwhile the most significant radiation hazard seldom gets noted: Radon gas is estimated to cause 20,000 cases of lung cancer in the US annually, second only to smoking.

a person living in building with average annual Radon concentration of 60 Bq/m3, would take annual effective dose of 1 mSv (60 x 0.017 = 1.02).

Here is a map of the United States with radon risk by county - with my own personal suggestion that odds are one need please note that within any given county there can be areas much higher or lower than the average for the county.
