The Surgeon General has warned that radon gas is the second leading cause of lung cancer in the United States after smoking, according to the Environmental Protection Agency (EPA). Radon gas, formed by the radioactive decay of uranium in the soil, cannot be seen or smelled, but it can enter homes and other buildings just about anywhere. Radon gas can also be found in well water. Radon detectors can be purchased for anywhere from $125 to $350.
Lung Cancer
Most of the risk of lung cancer associated with radon gas is due to the formation of radioactive daughter elements of radon and the emission of ionizing radiation as all these progeny decay. The energy from these subatomic particles damages lung tissue, and the ultimate result of that damage can be lung cancer. The EPA also notes that people who smoke greatly increase their risk of lung cancer if they are living in a home exposed to radon gas.
Testing
If you're worried about radon gas in your home or workplace, you can buy inexpensive kits for one-time tests. Also, radon detectors are available that can be set to monitor radon levels over the long term. A homeowner can do the testing, or a professional can be called in to test the structure. Some areas require radon testing before selling a home. Although that can be an added expense, the resulting peace of mind may be worth the extra effort and cost. The Maryland Department of the Environment suggests asking about the availability of testing at your local hardware store or calling the EPA's RADON HOTLINE (1-800-767-7236).
Home Repairs
If radon is detected in the soil around your home, one way to address the problem is to install a pipe and a suction pump in the ground that draws radon from the soil up to the roof, where any gas can be released and dissipated into the air. Other solutions include patching up any cracks in the floors or walls. Be sure to shop around and get a few estimates on the cost of this home improvement.
