Radon, impact to human health• EPA recommends that you • Fix your home if the radon level is 4 pCi/L or more• Because there is no known safe level of exposure to radon, EPA
also recommends that you consider fixing your home if the radon level is between 2 pCi/L and 4 pCi/L.
• EPA's estimate of 21,000 lung cancer deaths per year due to radon is based on the average radon concentration in American homes, which is about 1.3 pCi/L.
• The average concentration of radon in outdoor air is 0.4 pCi/L, or 1/10 of EPA's 4 pCi/L action level.
