Radon Testing
All outdoor and indoor air has some radon in it. Some building materials also can release low levels of radon. Radon can build up in the air in any home or building whether it has a basement, is sealed or drafty, or is new or old. There is no known safe level of radon and you should always aim to have the lowest level.
Radon-associated lung cancer can be prevented by limiting exposure to radon in indoor air. You can start by testing radon levels in your home and installing a radon reduction system, if needed.
Radon is an odorless, invisible, radioactive gas naturally released from rocks, soil, and water. Radon can get into homes and buildings through small cracks or holes and build up in the air. Over time, breathing in high levels of radon can cause lung cancer.
Impact of Radon
When you breathe in radon, radioactive particles from the decay of radon gas can get trapped in your lungs. It takes many years for lung cancer to develop. Most people don’t have symptoms until lung cancer is advanced and at that point it is harder to treat. For these reasons, it is important to take steps to reduce radon exposure throughout your life to help prevent lung cancer.
The U.S. Environmental Protection Agency (EPA) estimates that radon causes about 24,000 lung cancer deaths in the United States each year. Radon is the second leading cause of lung cancer deaths after cigarette smoke. People who smoke and are exposed to radon have a 10 times greater risk of developing lung cancer from radon exposure compared with people who do not smoke and are exposed to the same radon levels.
Testing
Testing your home is the only way to know if radon levels are high.
Test your home's radon levels:
- If it's never been tested or radon levels are unknown
- When preparing to buy or sell
- Before and after any renovations, especially after making any repairs to reduce radon levels
- Before making any lifestyle changes in the home that would cause someone to spend more time in the basement or lower level (like converting a basement to a bedroom)
