  • If short term testing is chosen, conduct testing on school days only (not holidays, vacations or weekends), between November 1 and March 31
  • If long term testing is chosen, conduct testing in a manner where at least half the test duration includes days between November 1 and March 31

    • Test all frequently-occupied rooms, including rooms with ground contact and rooms immediately above unoccupied spaces that are in contact with the ground, such as crawl spaces and tunnels.
    • Conduct follow-up testing in all frequently-occupied rooms that have radon ≥ 4 pCi/L
    • Take corrective measures in frequently-occupied rooms that have radon ≥ 4 pCi/L following Environmental Protection Agency (EPA) guidelines described in “Reducing Radon in Schools: A Team Approach.”
    • Re-test after corrective measures that reduce radon levels.
    • Report radon test results to the Minnesota Department of Health (MDH), using the MDH ‘School Radon Testing Form’ on the MDH school radon website.
    • Report radon test results at a school board meeting.
