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.")

Only by testing can a home be properly evaluated. 

Radon is a class "A" Carcinogen meaning radon is known to cause Lung Cancer. Other class "A" Carcinogens include: mustard gas, tobacco smoke, asbestos, benzene, and vinyl chloride.
