Radon is a colorless, odorless, radioactive gas that is produced due to the breakdown or decay of uranium in the soil.
Radon is known to be the number two cause of lung cancer. Radon damages DNA in your lung tissue which leads to mutation or tumor growth. Studies by the American Lung Association have determined that Radon is responsible for over 21,000 deaths annually in the United States.
Age of the home has no bearing on the level of radon that could be found inside. Sometimes newer homes can actually have higher levels due to techniques used to make the home more energy efficient. This can limit air exchange from the outdoors.
It is common for neighboring homes to have very different levels of radon. Differences in construction characteristics as well as differences in rock formations under the soil can change levels from house to house and neighborhood to neighborhood. It is recommended that all homes be tested for elevated radon levels.
The first step to dealing with radon is to have a test. If your home tests above 4.0 pico curies per liter of air, the EPA recommends "fixing" the home. Mad Dog Mitigation is licensed in Ohio for radon mitigation.
