The U.S. Surgeon General recommends ALL homes be tested for radon gas.
Radon is a naturally occurring radioactive gas released in rock, soil, and water that can build up to dangerous levels inside any home; this means new and old homes, well sealed homes and drafty homes, and homes with or without a basement. Radon gas is odorless and invisible and the only way to know if your home has a radon problem is to test for it.
Radon can increase your risk of lung cancer. Radon is the number one cause of lung cancer among people who do not smoke. It is the second leading cause of lung cancer for people who do. EPA estimates that radon causes more than 20,000 deaths from lung cancer each year in the U.S. If you smoke and your home has a high radon level, your risk of lung cancer can increase even more.
Homes with high levels of radon have been found in every state. In fact, radon levels can vary greatly from home to home, even levels next door can be very different.
Radon is measured in picocuries per liter of air (pCi/L), a measurement of radioactivity. In the United States, the average indoor radon level is about 1.3 pCi/L. The average outdoor level is about 0.4 pCi/L. The U.S. Surgeon General and EPA recommend fixing homes with radon levels at or above 4 pCi/L. EPA also recommends that people think about fixing their homes if their homes radon levels between 2 pCi/L and 4 pCi/L.
Four Seasons Home Inspection uses activated charcoal kits to measure for radon gas. We place two kits in the home for a minimum of 48 hrs. Once retrieved they are sent to a nationally certified radon testing lab for analysis. Findings are usually available in 1-2 days after they are picked up. Your radon report can be accessed thru our website.
