radon mitigation strategy

[Katie Huynh]

Hello,

I'm buying a home that is tested to have radon level 30.9 pCi/L. I'm not familiar with this subject. As I understand, the level of 4.0 pCi/L or over is considered high, but testing for positive radon is still a concerned. 

Can you give me insight of what the number is really telling? Do I need a radon mitigation system? If so, how much does it cost approximately? 

Thank you!
