This colorless, odorless gas can seep into your home, school or place of work. As the radon decays it can get trapped in your lungs when you breathe. The Environmental Protection Agency (EPA) has extensively researched and has listed radon as the second leading cause of lung cancer in the United States after smoking.
The EPA has established action levels of radon at 4 pCi/L or less. Even if you have a radon mitigation system it is important to test every two years. Testing can be done by a NRPP listed professional or you can buy do-it-yourself radon test kits, available at most hardware stores for around $40.00 (including lab fees).
If testing indicates levels higher than 3.9 pCi/L, it is important to hire a Certified Radon Professional listed with the National Radon Proficiency Program (NRPP). Although certification is not required by law, a Certified Radon Professional has been educated in important protocols and will insure the system is installed properly and safely.
