A 1993 study found that approximately 74% of homes built on the Rincon Formation, or on alluvium or soils derived from the Rincon Formation, showed interior radon concentrations in excess of 4 picocuries per liter (pCi/L), the U.S. EPA action level, and 26% had measured levels of radon over 20 pCi/L. [18] According to the U.S. EPA, non-smokers ...
Radon, a byproduct of naturally decaying uranium, is estimated to cause thousands of deaths each year nationwide. Here's how to protect yourself.
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]
More than 26% of Erie County homes tested for radon between 2010 and 2020 have detected high levels of the odorless, colorless, tasteless, and deadly gas.

The area of the soaking pools has been prone to illegal camping, vandalism and trash; a volunteer group, the Hot Springs Angels, cleaned it and educated visitors under an agreement with the Forest Service. [5] The water is high in uranium and radon. [4] After a death in October 2022, the Forest Service destroyed the pools as a public danger. [5]
Radon and its isotopes, parent radionuclides, and decay products all contribute to an average inhaled dose of 1.26 mSv/a (millisievert per year). Radon is unevenly distributed and varies with weather, such that much higher doses apply to many areas of the world, where it represents a significant health hazard.
