Radon Risk Assessment is based on the assumption that most people work outside the Home 8 hours per day. The risk assigned by EPA to each level of radon exposure assumes 16 hours per day in the home.
For Stay at Home Moms & Dads this means that the risk of getting Radon caused Lung Cancer is one third higher than the risk the tables provide.
Fifty-five percent of your exposure to all Radiation is in the form of Radon in the home. This estimate is based on the assumed exposure level of 1.3 pCi/l which is the average in door radon level for the nation.
The exposure level of 1.3 pCi/l averages Red, Orange & Yellow Counties for the whole United States. Red Counties have a predicted indoor radon level of 4 pCi/L. Orange Counties have a predicted indoor radon level of between 2 to 4 pCi/L. Yellow Counties have a predicted radon level of less than 2 pCi/l.
Nearly all southern Wisconsin Counties are red counties.
Even though a county may be rated as Orange or Yellow high levels of radon are still found inside homes in these counties.
"The World Health Organization says radon causes up to 15% of lung cancers worldwide." (From the EPA document "Health Risks.")
