Radon Mitigation

On Wednesday, you learned all about radon. When it was discovered, the health effects of radon exposure and even it's atomic number. 

But, how does it enter your home and how do you get rid of radon? 

How radon enters your home
Radon is an odorless, colorless gas that occurs naturally when the uranium in the soil and water breaks down. Radon can be released into the air when you use tap water. Some building materials, like certain types of granite and concrete, can also give off radon, but it's rarely enough to cause problems.

However these are small risks compared to radon entering through foundation cracks and a dirt floor in your basement or crawl space. In fact, in the U.S. the primary source of radon gas found in homes is caused by radon entry from the soils.



Radon mitigation
According to the EPA, an effective way to reduce radon levels in your crawl space is to install a high-density vapor barrier (We recommend CleanSpaceTM) over the dirt floor.

This is a passive method to help reduce radon intrusion. However if you need an active method to control radon, you can easily install a vent pipe and fan to work in conjunction with a high-density vapor barrier. 

CleanSpaceTM is a thick, high-density crawl space vapor barrier. It's a 20-mil, 7-ply thick barrier of high and low-density polyethylene with polyester-cord reinforcement, which is also treated with an antimicrobial finish that protects against mold and mildew growth, in addition to acting as a passive radon mitigation system.
