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. For more information, see the statement ‘Radon Licensure Changes due to Temporary Injunction’.
To be eligible for a measurement professional license, all applicants must:
Approved courses:
Upcoming courses:
Approved exams:
(If you take an in person class, they may offer the NRPP or NRSB exam after the course)
Licensed professionals must submit a list of continuous monitors and passive devices that they use to measure radon. Continuous monitors used must be approved by either the NRPP or the NRSB. Passive radon devices must be analyzed by licensed radon laboratories.
Licensed Radon Professionals are required to submit a QA plan for measurement based on U.S. EPA guidance. Existing QA plans may be accepted. If you have a previously developed QA plan, you can submit it for review during the application process. You are not required to use the MDH QA plan template.
Many radon device manufacturers and laboratories provide a QA plan for their users to customize and use. Contact your device manufacturer or approved radon laboratory to see if they can provide you with a QA plan specific to their devices. If they do not have a QA plan or you would rather create your own, then use the MDH QA Plan Template to develop a measurement QA plan.
Note: If you wish to be a radon mitigation professional, but will not be placing or retrieving radon test devices, then a shorter QA plan will be acceptable. MDH will still need to know which approved radon laboratory will supply your test kits and how you will comply with section 10.2 of the Soil Gas Mitigation Standards. The ANSI/AARST Soil Gas Mitigation Standards for Existing Homes section 10.2 requires a post-mitigation radon test be conducted and who can conduct the post-mitigation measurements.
All Minnesota radon professional licenses are valid for 1 year from the date of issuance. Professionals must apply to renew their measurement license at least 30 days before the license expires.
In order to renew a measurement license, individuals are required to complete 8 hours of continuing education approved by MDH. Classes approved by NRPP or NRSB are automatically accepted.
Measurement professionals must submit a listing of all radon tests completed to MDH. These reports are due quarterly (January 30, April 30, July 30, October 30) and must be submitted online through the radon licensing system. Information must include:
All data can be entered into a spreadsheet and uploaded as a .csv file (template is available online) or entered individually.
Radon measurement professionals must follow standards of conduct and work practices:
Applications are completed online through the radon licensing system. Documents are to be uploaded through the radon licensing system. No paper applications will be accepted. Applicants must submit:
A non-refundable fee of $150 payable by e-check, credit card, or debit card.
