RADON MITIGATION – How to Reduce Radon in Your Home
The results of a radon test fall into one of three groups. The following are the Environmental Protection Agency (EPA) recommendations:
Radon level 0-1.9 pCi/L: No level of radon is safe, but reducing levels of radon below 2 pCi/L is difficult.
Radon Level 2.0-3.9 pCi/L: Consider fixing the radon level.
Radon Level 4.0+ pCi/L: A qualified radon mitigation contractor should take corrective action to reduce the homes indoor radon levels.
In a real estate transaction 4.0 pCi/L and higher is the level at which action is taken by a seller, however a radon result of 3.8 pCi/L, for example, deserves serious consideration for mitigation after purchasing the home.
Although it’s not the U.S. standard, the World Health Organization has created an action level for mitigation at 2.7 pCi/L and higher.
