Overview
Radon is a colorless, odorless, radioactive gas, which is found in all homes in varying amounts depending on the locality. Radon levels are measured in picocuries per liter of air (pCi/L) where a picocurie is a measure of radioactivity. The national average level within homes is about 1.3 (pCi/L). Not everyone who is exposed to elevated levels of radon gas will develop lung cancer, but your risk of getting radon-induced lung cancer increases as your exposure to radon gas increases. Smokers who have high radon levels in their homes are at an especially high risk for getting radon-induced lung cancer.
This course will provide the student with step-by-step guidance on how to build radon resistant homes. By specifying various inexpensive construction methods and procedures, radon levels can be effectively reduced. A very basic radon reduction system can reduce radon levels as much as 50%; the same system can be easily upgraded to provide additional radon level reduction.
The student must take a multiple-choice quiz consisting of twenty-five (25) questions at the end of the course to obtain PDH credits.
