Some Information About Radon


Source: Illinois Department of Nuclear Safety (IDNS)

Radon is a radioactive element that is part of the radioactive decay chain of naturally-occurring uranium in soil. Radon is invisible, odorless and cannot be tasted. Unlike carbon monoxide and many other home pollutants, radon's adverse health effect, lung cancer, is usually not produced immediately. Thus you may be exposed to radon for many years without ever suspecting its presence in your home.

The USEPA action level for radon is 4.0 picocuries per liter of air (pCi/L). The risk of developing lung cancer at 4.0 pCi/L is estimated at about 2 lung cancer deaths per 1000 persons. That is why USEPA and IDNS recommend reducing your radon level if the concentration is 4.0 pCi/L or more.

IDNS projections by county in northeastern Illinois regarding percentage of homes with radon levels of 4.0 pCi/L or more:
