BERRIEN COUNTY, Mich. -- January is Radon Action Month, and the Berrien County Health Department is reminding community members about the dangers of radon and offering free radon testing kits.

"Radon is an invisible, odorless radioactive gas that can be found in homes and is the second-leading cause of cancer in the U.S. after smoking," the BCHD said. "The Environmental Protection Agency estimates radon is responsible for about 20,000 lung cancer deaths in the country each year."

Officials say radon comes from the natural decay of uranium that is found in nearly all soils and can move up through the ground into the air and enter homes through cracks in the home’s foundation. There are no short-term side effects or a distinctive color, smell or taste to alert individuals of elevated radon levels in their home. Testing is the only way to determine if radon levels are at an actionable level.

Home radon testing kits can cost between $10 and $200, but during the month of January, the BCHD is offering free radon testing kits to community members while supplies last.

“Many residents often overlook radon or are simply unaware of its presence,” said Nick Margaritis, BCHD’s manager of environmental health services. “The Berrien County Health Department is taking action against this hidden danger and providing free testing kits to our community. By providing education about radon and free testing kits, we are enhancing the safety and health of Berrien County residents.”

Testing kits may be picked up at BCHD’s offices in Benton Harbor, 2149 E. Napier Ave., and Niles, 1205 N. Front St. during business hours: 8 a.m. to 5 p.m. Monday through Thursday and 8 a.m. to 2:30 p.m. Friday.

It is recommended residents test for radon every two to five years.

According to the Michigan Department of Environment, Great Lakes, and Energy, one in every four homes is believed to have radon levels exceeding the federal action level. Elevated radon levels have been found in all 83 Michigan counties.

"While elevated radon levels pose a threat to community health, they can easily be addressed through a radon mitigation system once identified," the BCHD said.
