Tjernlund Radon Vac™ System

Protect your Family from Radon.





The Environmental Protection Agency (EPA) has designated January as National Radon Action Month. The promotion’s objective is to alert the public about the health dangers of radon gas and provide information on finding and fixing the problem if it exists.

According to the EPA’s website (, “You can’t see, smell, or taste radon, but it could be present at a dangerous level in homes. Radon is the leading cause of lung cancer deaths amount nonsmokers in America and claims the lives of about 20,000 Americans each year.

“Exposure to radon is a preventable health risk, and testing radon levels in your home can help prevent unnecessary exposure. If a high radon level is detected in your home, you can take steps to mitigate the radon to protect yourself and your family.”

The web site further states: “There are several proven methods to reduce radon in your home, but the one primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside.”
