Licensing for Radon Professionals - EH: Minnesota Department of Health

Licensing for Radon Professionals

On December 28, 2018, a Ramsey County District Court judge issued an order in an on-going lawsuit filed against the Minnesota Department of Health (MDH). That order, in effect, prevents  MDH from enforcing certain radon mitigation statutes and rules that were scheduled to become effective on January 1 of 2019. Under the order, MDH for the time being cannot regulate or enforce the statutes and rules that apply to radon mitigation professionals that conduct mitigation in residences. Until further order of the Court, MDH must comply with the order. Other parts of the radon statutes and rules are not affected by the Court’s order. The radon measurement aspects of the statute and rules remain unchanged. If you are conducting radon measurement in a building you do not own or lease, you need to have a radon professional license.

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.

Who needs a license?

Professionals that measure and companies that perform radon lab analysis, must be licensed by MDH. Mitigation professionals and companies that mitigate non-residential buildings must be licensed.

  • Measurement professionals: an individual who places or 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 non-residential 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 in a non-residential building.
  • 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.
