Radon Testing Plan

According to Minnesota Statute 123B.571, school districts that receive health and safety revenue to conduct radon testing must conduct the testing according to this ‘Radon Testing Plan'.

  • 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
  • Use certified radon testing devices, as listed by either the:
    • 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
    • Mitigate or take corrective measures in frequently-occupied rooms that have radon ≥ 4 pCi/L following ANSI/AARST ‘Radon Mitigation Standards for Schools and Large Buildings’ (ANSI/AARST RMS-LB)
    • Re-test after corrective measures to show radon reduction
    • Report all radon test results to MDH on the ‘School Radon Testing Reporting Form’ at the conclusion of the testing project (after all follow-up testing and any corrective measures have been shown to reduce radon levels).
    • Report radon test results at a school board meeting.
