Radon Gas - What Should I Do if I Find It In My Home?

The first thing you should do is determine whether the level of radon in your home is acceptable to you. Radiation always presents an element of health risk, but higher levels are, of course, more dangerous than lower ones.

You can compare the reported level against the guidelines that have been set by the EPA. Various groups have also independently established levels that differ from the EPA.
The American Society of Heating, Refrigeration, and Air Conditioning Engineers has set the lowest level, which suggests a radon action level of 2 picocuries per liter or less for commercial buildings and residences.

The EPA has adopted a 4 picocuries per liter of air action level. The U.S. Mine Safety and Health Administration, on the other hand, suggests an action level of 16 picocuries per liter (while miners are in underground mines).

If you feel you have high levels of radon in your home, we recommend you increase the ventilation, limit the time anyone spends in the areas with highest concentrations, and consider other abatement mitigation methods.

You should also consider contacting your State's radiation control program, regional EPA office, or other qualified professionals to determine what action might be taken to reduce your exposure.
