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
Life.
