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 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 consideration 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.
