Radon gas is the second leading cause of lung cancer in the U.S. This naturally occuring, colorless and odorless gas can seep into your home without your knowing it. Jefferson County Public Health urges homeowners to test their home for radon gas. Testing requires all windows and doors be closed, but is simple to do. Stop by our new location at 645 Parfet Street in Lakewood to get your test kit. During the month of February 2014, kits will be available for free on a first come, first serve basis. Once the free coupons run out, residents will be charged $10.00 for each kit. Long-term test kits are also available at local hardware stores, supermarkets and other retail outlets. For more information on radon, radon testing, and radon mitigation, call 1-800-846-3986 or JCPH Environmental Specialist John Moody at 303-271-5714.
