Design of Radon Resistant Residential Structures
Jeffrey Havelin, P.E.
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). Smokers who have high radon levels in their homes are at an especially high risk for getting radon-induced lung cancer. Not everyone who is exposed to elevated levels of radon gas will develop lunge cancer, but your risk of getting radon-induced lunge cancer increases as your exposure to radon gas increases.
This course will introduce a step-by-step design procedure on how to build radon resistant residential structures. By specifying various inexpensive construction methods and procedures during construction 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.

Step by Step Guide on How to Build Radon-Resistant Homes. This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of course materials. You will be quizzed on the attached document in its entirety.
This course teaches the following specific design skills:
This course would be very informative for engineers or architects who are involved with the design, or construction of residential structures.
Consumers are becoming
more aware that radon is a health risk, and building a home with radon-resistant
features could give buyers one more reason to purchase a home from you, or to
request your design services in the future. If you are involved with the home
building industry, offering homes with radon-resistant features can attract
more potential home- buyers, which can translate into closing more sales or
more consulting business. This course will provide you with the design skills
required to build radon-resistant features into your design plans or assist
in retrofitting these features into an existing structure.

At the completion of this class the design professional should be able to design and size a complete radon reduction system (depressurization system) that can be used in various types of residential or small commercial applications.
