More than 26% of Erie County homes tested for radon between 2010 and 2020 have detected levels that equal or exceed the Environmental Protection Agency's "action level" of 4 picoCuries per liter ...
High radon levels in a Minnesota (USA) basement with a passive under slab vent pipe system can be seen in the left half of the graph. After installation of a radon fan (ASD), a permanent reduction in radon levels to approximately 0.6 pCi/L can be seen in the right half of the graph. The most common approach is active soil depressurization (ASD).
In a working mine, the radon level can be controlled by ventilation, sealing off old workings and controlling the water in the mine. The level in a mine can go up when a mine is abandoned; it can reach a level which can cause the skin to become red (a mild radiation burn). The radon levels in some of the mines can reach 400 to 700 kBq m −3. [17]
It was determined that radon levels in his home's basement were in excess of 100,000 Bq/m 3 (2.7 nCi/L); he was told that living in the home was the equivalent of smoking 135 packs of cigarettes a day, and he and his family had increased their risk of developing lung cancer by 13 or 14 percent.

Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
Jan. 18—ATHENS — January is National Radon Action month, and each year University of Georgia Cooperative Extension sponsors a poster contest for students across the state to help bring ...
The goals of NRAP are to continue efforts set forth by FRAP to eliminate radon induced cancer that can be prevented by expanding radon testing, mitigating high levels of radon exposure, and developing radon resistant construction. [87] NRAP also aims to reduce radon risk in 5 million homes, and save 3,200 lives by 2020. [87]
Radon levels in homes can be reduced by: * increasing under-floor ventilation; * installing a radon sump system in the basement or under a solid floor; * avoiding the passage of radon from the basement into living rooms; * sealing floors and walls; and * improving the ventilation of the house .
