ROCKVILLE, Md. (AP) — Montgomery County schools officials say they're testing for radon again in more than two dozen public school buildings after initial tests showed elevated levels.
Parents were informed last week about elevated ratings, including some that were discovered as far back as 2012. According to the Environmental Protection Agency, exposure to high levels of the naturally occurring, odorless gas can cause lung cancer.
Interim Superintendent Larry Bowers said in a statement that according to the school system's protocols, retesting should have already occurred. He says steps will be taken to correct the problem immediately if the results show levels higher than EPA-approved levels. In some locations, he says remediation has already taken place and testing will be conducted as a precaution.
