Montgomery County Public Schools has completed new radon tests at Westland Middle School in Bethesda, and results show at least 3 rooms in the building have radon levels above the 4.0 picocuries per liter of air (pCi/L) limit recommended by the U.S. Environmental Protection Agency. School systems are expected to take immediate action to reduce radon levels when they exceed that number.
The rooms at Westland found to be over the radon limit are:
It appears MCPS held on to the results before releasing them, as documents suggest the lab analysis of the test kits was performed between December 22 and December 24. The tests were conducted by KCI Technologies and M.A. Cecil and Associates.
The presence of unsafe levels of radon in 26 MCPS schools, and the failure of the system to take action or report previous test results to parents, was first uncovered by the Parents' Coalition of Montgomery County, MD back in November.
Radon is described by the EPA as "a human carcinogen and a serious environmental health problem," and a "radioactive gas."
