MN School Radon Testing Plan

The Minnesota Department of Health states that all schools that receive health and safety revenues specifically for radon testing, must follow the MN Department of Health Radon Test Plan. The school district may choose to conduct either long term or short term radon testing. All frequently occupied rooms should be tested. Rooms above crawl-spaces or tunnels should also be tested for radon. Minnesota School radon test results need to be reported to the MN Department of Health (MDH) using a specific ‘ School Radon Reporting Form  ‘. The results of the radon test should also be reported at a school board meeting.

Prior to the radon testing process, administrative support should be obtained. All teachers should be informed of the test placement, duration, and radon testing methods. The decision should be made to follow a short term test (2-4 days) if the results are needed quickly. A short term test may also be considered if:

  • There is a possibility the test kits may disappear easily if deployed for a longer period of time.
  • If windows and doors can remained closed except for normal entry and exit during the testing period.
  • If the indoor ventilation rate is similar through-out winter.

We recommend that Minnesota child daycare center radon testing also follow the testing directives put in place by MDH for school age children.
