The Indoor Radon Program, within the Environmental Management Branch, seeks to
reduce the health risk from radon exposure by increasing awareness, identifying
areas of high radon potential, and encouraging all Californians to test their
homes for radon, fix their homes if they have a radon problem, and build new
homes radon-resistant. Test. Fix. Save a
Alameda County Winter Radon Screening Survey
As part of the annual Winter Radon Screening Survey, CDPH will be sending letters to many Alameda County residents to let them know about our free radon test kits. If you live in Alameda County you can still get a free test kit even if you didn't receive this letter. A limited number of free test kits are available.
Order Your Free Test Kit from Alpha Energy Labs online or toll-free (800) 324-5928
If you live outside of Alameda County, you can order a test kit for only $10.95.
Testing your home for radon takes only a few days and does not interfere with your normal household activity. Once you've returned your test kit, as instructed, you will receive information about your home's radon risk and how to reduce exposure. The information also helps to create a statewide map of areas that may have radon.
The presence of radon can vary widely within a county or even within a neighborhood, and the only way to know if your family is being exposed is by having your home tested.
