The IEMA Radon Program and the Illinois Department of Public Health recommend that levels in homes be less than 4.0 pCi/L. If levels exceed this number, radon mitigation should be used to reduce the levels and decrease the risk of lung cancer. The USEPA recommends you test your home for radon every two years.
