California Radon Testing is located in Wheatland, California, about 15 miles north of Sacramento. Much of our testing is performed for real estate agents and homeowners in the Sacramento area and surrounding foothills. We are willing to travel and have performed testing in the Lake Tahoe area and Bay area communities.
California Radon Testing is listed on the State of California Department of Public health website. The website can be found here:
Radon is a naturally-occurring gas that enters the home from the soil beneath it. Radon cannot be seen or smelled and must be tested for to determine it's presence and concentration. It comes from natural deposits of uranium, which slowly degrade and release radon gas. Radon enters the home by the process called the thermal stack effect. The warm air in the house creates a vacuum that draws radon in with soil gases from beneath the house.
Scientific evidence has identified Radon as the second leading cause of lung cancer, behind cigarette smoking. Radon is classified as a Class A Carcinogen. The EPA and Surgeon General recommend that people not have exposures above 4 picocuries per liter (pCi/L) on a long term basis. This is not a health-based number but was created by the EPA based on an estimated practical level to recommend mitigation. There is no safe level of Radon gas and approximately 2/3 of Radon-caused cancers occur below this level.
The fact that radon is naturally occurring creates a problem for the regulatory community. It is very difficult to regulate naturally-occurring chemicals with no human-realated sources. There are no Responsible Parties or Source Areas to direct regulations at. Because of these issues, California currently has no regulations requiring mitigation or testing for Radon.
