Home Radon Test Kits

Radon testing involves measuring the levels of radon gas in indoor spaces to assess potential health risks. It is a straightforward process that can be done through do-it-yourself test kits.

What is radon and why is it dangerous?

Globally, residential radon exposure alone is estimated to cause 84,000 lung cancer deaths every year, according to the World Health Organization (WHO). In the United States, the Environmental Protection Agency (EPA) 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.

How does radon enter your home?

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.

How can you test for radon?

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.

How can you reduce high radon levels?

If testing shows radon levels above recommended limits (4 pCi/L in the U.S. and 200 Bq/m³ in Canada), radon mitigation systems can help.

Common solutions include:

• Active soil depressurization systems to vent radon outdoors
• Sealing cracks and openings in the foundation
• Increasing ventilation in basements and crawl spaces
• Installing radon sumps in high-risk properties

Lowering radon levels significantly reduces long-term lung cancer risk, keeping your family safe.
