What's the Risk with Radon?
Radon - an odorless, tasteless, invisible gas.
There is no scientific doubt that exposure to high Radon gas levels can cause lung cancer. EPA estimates that approximately 20,000 people die each year as a result of radon exposure and recommends that ALL homes built in high radon areas incorporate radon prevention measures at the time of construction. The state of Indiana is classified as a Zone I Radon Area. This means that the average home in the state exceeds the EPA action level of 4.0 pCi/l. A pico curie ("peeko curee") is a unit of measurement for radiation. Living in a home at 4.0 pCi/l is the equivalent of each family member smoking half a pack of cigarettes every day. For this reason, the World Health Organization lowered its recommended action level from 4.0 to 2.7 pCi/l in 2009.
