Indoor air: test for radon
Radon is a naturally-occuring gas that enters your home seeping up through the ground. As it breaks down, it releases radioactive particles that you can breathe in. You can’t see or smell it, and you won’t feel it in your lungs. However, exposure can raise the risk of developing lung cancer 10-20 years after exposure.
- If you live in a house or apartment below the third floor, test for radon.
- Get a kit at the hardware store. The best time to test is in winter, when doors and windows are closed.
- There is no safe level of radon exposure. EPA recommends action if concentrations at home measure 4 pCi/L; the World Health Organization says 2.7 pCi/L.
- Hire a professional to install a system of fans and vents to reduce radon indoors. EPA advises people to use a certified contractor that can make sure the air pressure in your home is drawing air out. Costs range from $500 and $2500.
- The way you maintain your home can make a big difference to your family’s health. Get a healthy homes checkup with our guide and tips.
