The 1993 Virginia General Assembly passed legislation that requires all schools in the Commonwealth to be tested for radon after July 1, 1994, as well as any new school buildings. Each school is required to maintain files of radon test results. The full text of the law is provided at the bottom of this page.
In general radon test results for schools were below the EPA guidance of 4 pCi/L of radon in air. Although there were several test results that indicated high radon levels, a review of the data and testing methodology indicates most of these test results were not valid for any of the following reasons: insufficient test period and improperly testing closed areas, such as boiler rooms and storage rooms.
For the few schools that did have elevated radon levels, the school's ventilation system was found not to be working properly, i.e. dirty filters, unbalanced air flow. In these instances, radon levels were easily reduced after correcting the ventilation problem.
If you have any questions regarding radon levels in any particular school, contact that school's administration.
