Post Mitigation

Post Mitigation

Once your home has been mitigated, post mitigation radon testing should be done to ensure that radon levels in your home are below the EPA safe level.  Once the levels are confirmed to be below the safe level, EPA recommends that mitigated homes be retested every 2 years to ensure your system continues to keep indoor air radon levels below the EPA safe level.  Arizona Radon Professionals recommend that your system be inspected annually, as well.  Generally, the initial post mitigation test kits are included with the mitigation system installation and the homeowner does the testing.  The results are sent directly to Arizona Radon Professionals and we will share the results with you once they are received. 

Arizona Radon Professionals generally do not perform the initial post mitigation testing after they mitigate a house in order to avoid potential conflict of interest.

Arizona and Radon Gas

Radon presence in Arizona is similar to the national average.

A state indoor radon sampling survey conducted in 1987-89 by the Arizona Radiation Regulatory Agency suggest that about 1 out of 15 Arizona homes may contain radon concentrations in excess of the EPA recommended action level of 4.0 picocuries per liter of air (4.0pCi/L).
