Licensing for Radon Professionals - EH: Minnesota Department of Health

Licensing for Radon Professionals

The Minnesota Radon Licensing Act (Minnesota Statutes 144.4961) was passed by the legislature and signed into law in May 2015. This act gives Minnesota Department of Health (MDH) the authority to write rules and enforce laws related to the radon industry in the state.

All licensing requirements go into effect January 1, 2019.

Who needs a license?

Professionals that measure or mitigate radon and companies that mitigate radon or perform radon lab analysis, must be licensed by MDH. You can apply online through the radon licensing system.

  • Measurement professionals: an individual who places and retrieves test device in buildings they do not own or lease.
  • Mitigation professionals: an individual who installs or designs a radon mitigation system in a building they do not own or lease, or provides on-site supervision of mitigation work.
  • Mitigation companies: a business or government entity that employs one or more licensed mitigation professional and performs or authorizes employees to perform radon mitigation.
  • Radon Analysis Laboratories: a business or government entity that analyzes passive radon test devices for the presence or concentration of radon. Contact MDH for information on licensing as a laboratory at 651-201-4601.
