Why should home radon testing be done?

Indoors, radon can accumulate in the lower levels of homes where it can adversely affect human health. Radon has been found to cause lung cancer in humans. Outdoors where radon is diluted to low concentrations, radon poses little risk to humans. As concentrations of radon increase, there is a greater chance of contracting lung cancer. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

Radon can be found all over the US and in any type of building. It is important to test your home, because families are most likely to get the greatest exposure in their homes. It is where most people spend most of their time. The EPA and the Surgeon General recommend testing in all homes below the third floor. If a home has high levels of radon, there are simple and relatively low cost ways to reduce the radon levels. For more information about lung cancer, see the following web pages:

How can you get radon test kits, and mitigate your home if needed?

Find a Radon Test Kit or Measurement and Mitigation Professional.

Visit our Contacts Page for links to your State's Indoor Radon Program. Your State Radon Program can identify sources for obtaining radon test kits. Follow the instructions that come with the test kit. After use, test kits should be immediately mailed to the lab specified on the test kit. Test results will be mailed to you.

Your State Radon Program can also provide referrals for competent radon mitigation contractors in your area.
