Radon Test Kits for Homeowners

Globally, residential radon exposure alone is estimated to cause 84,000 lung cancer deaths every year, according to the 

 reports that radon is responsible for about 21,000 lung cancer deaths annually. Radon is a naturally occurring radioactive gas that forms when uranium in soil and rock breaks down. It is colorless, odorless, and tasteless—making it impossible to detect without testing. Long-term exposure to high radon levels is the second leading cause of lung cancer after smoking.

Radon seeps into buildings from the ground through cracks in foundations, gaps around service pipes, floor joints, and other structural openings. Even well-sealed homes can be affected. Because radon gas can build up indoors, especially in basements and ground-floor spaces, it’s important to test regularly to understand your exposure risk.

Radon testing is the only way to know your home’s radon levels. Short-term tests provide a quick snapshot, while long-term tests give a more accurate annual average. Using a laboratory-certified radon test kit—such as those from Radonova—ensures accurate results.

If testing shows radon levels above recommended limits (4 pCi/L in the U.S. and 200 Bq/m

in Canada), radon mitigation systems can help.
