As part of the Franklin Township supervisors meeting, township supervisors have asked that this information be offered to the public.
The board received this information from DEP by mail.
The letter notes that January is National Radon Action Month, and the Department of Environmental Protection is spreading awareness through its quarterly webinar series, DEP at Home, on Wednesday, Jan. 16, from 7 to 8 p.m.
The webinar features a presentation and live question-and-answer session with Robert Lewis and Matthew Shields of DEP's Bureau of Radiation Protection and Kevin Stewart of the American Lung Association.
Radon is a colorless, odorless, radioactive gas that occurs naturally through the breakdown of uranium in soil and rocks. It can seep into homes through cracks in basements and foundations, and can build up inside to concentrations many times the recommended level.
Radon is responsible for an estimated 20,000 lung-cancer deaths in the United States every year, and about 40 percent of Pennsylvania homes have radon levels above the U.S. Environmental Protection Agency's action level of four picocuries per liter. While radon problems may be more common in some regions, the potential exists for any home to have high radon levels.
Pennsylvania is particularly prone to elevated radon levels, and the only way to know if there is a radon problem is to test the home. DEP recommends testing all homes and public and private buildings. The best time to test is during the cold-weather months, when homes and buildings are closed and radon is most likely to build up to unhealthy levels.
Residents may hire a certified radon testing company, though it is easy to perform a radon test by using a kit that can be purchased at a home improvement store or a Pennsylvania-certified radon laboratory. Completed test kits are to be sent to a Pennsylvania-certified lab, where the samples are analyzed and the results are then sent to the resident. If results reveal radon levels above the action level, a radon mitigation system may be necessary.
Radon mitigation systems cost between $700 and $1,200 and require minimal maintenance. Most home or building owners choose to hire a radon mitigation professional to install the system.
