Introduction
The radioactive gas radon is estimated to cause about 21,000 lung cancer deaths per year in the U.S., according to the Environmental Protection Agency’s (EPA) 2003 Assessment of Risks from Radon in Homes. It represents the second largest cause of lung cancer in the world. Underground workplaces such as basements, mines, caves and utility shafts can have significant levels of Radon as well as above ground workplaces in Radon affected areas. In the U.S., new homes are not required to meet a specified radon level. While radon problems may be more common in some areas, any location may be affected. The only way to know about is to test. Understanding the potential radon levels allows proper systems installation during construction versus after construction vent system.
