The Dangers of Radon In Your Home

Get A Read On Radon


Radon escapes naturally from soil as a colorless, odorless, radioactive gas that can seep through the foundation of your home and reach toxic levels.

How toxic? Radon contributes to 21,000 lung-cancer deaths annually, according to the Environmental Protection Agency (EPA). By comparison, carbon monoxide kills an average of 439 persons each year. The EPA sets the maximum acceptable radon exposure at 4 picocuries per liter of air (pCi/L). However, because there's no "safe" level, the EPA recommends you take action when the level in your home reaches 2 pCi/L. Outdoor radon levels average about .4 pCi/L.You Can Test For Radon In Two Ways:

DIY Tests. Buy radon test kits at home centers or through National Radon Program Services. Testing takes two days to a year in a closed-up house before you return the test to a laboratory for the results. Radon levels vary daily, so longer tests mean greater accuracy. Retest after making repairs.

•Professional Tests. A trained radon professional's electric monitor shows how radon levels fluctuate during the test period. Home buyers may trust professional tests more because they are performed independently of home sellers.
Fix The Problem...ASAP

In general, treat radon reduction like any home improvement and obtain multiple bids before hiring a licensed contractor. Fixing most radon problems costs on average between $800 to $2,000 (depending largely on the size of your home).  The National Environmental Health Association offers a list of questions to ask your radon contractor. The EPA has also links to California's radon control agency.
