January is National Radon Action Month, and the U.S. Environmental Protection Agency (EPA) is working with our partners to spread the word about radon health risks in homes, the importance of testing, and steps homeowners can take to reduce risk in the Rocky Mountain and Great Plains states of Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming.  

Radon is a known carcinogen and is estimated to cause more than 20,000 lung cancer deaths each year in the U.S.  In fact, the colorless, odorless gas is the leading cause of lung cancer in nonsmokers. The good news is the health risks and impacts are preventable — testing and reducing radon levels in your home, and saving lives, is easy. 

This year’s Call to Action, “Test Your Nest!” is especially important to our region’s residents as large portions of these states are at risk for high indoor radon levels that can cause lung cancer. The best way to protect against radon is to perform a simple, low-cost test of your home.  EPA recommends homeowners take action to reduce radon levels when they exceed the action level of 4.0 picocuries per liter (or 4pCi/L).

“Understanding your home’s radon levels is one of the most important steps you can take to protect you and your family’s health,” said EPA Regional Administrator KC Becker. “I encourage you to take some time to check your nest this winter, so you can be sure that quality time spent inside with friends and loved ones is not just comfortable, but safe.”
