Radon is a Radioactive Gas
Radon is a radioactive element that is part of the radioactive decay chain of naturally occurring uranium in soil. You can’t see radon. You can’t smell radon and you can’t taste radon. 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 7 lung cancer deaths per 1000 persons. That is why USEPA and IEMA recommends reducing your radon level if the concentration is 4.0 pCi/L or more. Lung cancer in humans arising from radon exposure is recognized by the following health and environmental organizations:
- American Medical Association
- U.S. Surgeon General
- U.S. Department of Health and Human Services
- U.S. Public Health Service
- U.S. Environmental Protection Agency
- Center for Disease Control
- National Academy of Science
- National Cancer Institute
- World Health Organization
