__________________________________________________________________________
Anyone who designs or installs a radon mitigation system in an existing non-residential building that they do not own or lease. The license allows mitigation professionals to provide on-site supervision of unlicensed radon mitigation technicians. The mitigation license allows individuals to do measurement activities.
All non-residential mitigation professionals that are employed or contracted by a business must work under a licensed mitigation company. A sole proprietor radon mitigation professional, who does not employ or contract with a licensed radon mitigation professional, is not required to obtain a mitigation company license.
A radon mitigation professional license is a dual measurement and mitigation license and allows professionals to do radon measurement as well. No additional license is needed.
What you need to get licensed
Training and Exam
To be eligible for a mitigation professional license, all applicants must:
- Complete an approved radon measurement course
- Pass an approved radon measurement examination (the course completion exam at the end of an online course is not sufficient)
- Complete an approved radon mitigation course
- Pass an approved radon mitigation examination (the course completion exam at the end of an online course is not sufficient)

Approved Testing Devices
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.
Quality Assurance (QA) Plan
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.
Continuing Education and Renewal
All Minnesota radon professional licenses are valid for 1 year from the date of issuance. Professionals must apply to renew their license at least 30 days before the license expires.
In order to renew a measurement license, individuals are required to complete 12 hours of continuing education approved by MDH. Classes approved by NRPP or NRSB are automatically accepted.
Reporting Requirements
Non-residential mitigation work completed by a radon mitigation professional must be reported to MDH by a licensed radon company or a licensed sole proprietor mitigation professional. These reports are due quarterly (January 30, April 30, July 30, October 30) and must be submitted online through the radon licensing system. The specific data to be submitted are described in the Licensing for Radon Mitigation Company and Sole Proprietor
Measurement work completed by a radon mitigation professional must also be reported. The specific data to be submitted are described in the Licensing for Radon Measurement Professionals. Pre- and post-mitigation radon concentration results conducted or collected as part of the non-residential mitigation work are to be reported as part of the companyâ??s mitigation reporting.
Standards of Conduct and Work Practices
Radon mitigation professionals must follow standards of conduct and work practices:
- Operate according to the QA Plan approved under the license
- Use measurement devices approved by NRPP or NRSB
- Notify the commissioner of any change to the license within 30 days
- Maintain proof of license while on a project site
- Use only radon laboratories licensed by MDH
- Maintain radon test and calibration records for 3 years
- Not interfere with MDH inspection or audit
- Comply with ANSI/AARST protocols for conducting radon measurement in homes, multifamily buildings and schools/large commercial buildings
- Comply with ANSI/AARST protocols for conducting radon mitigation in schools/large commercial buildings
- Make available, to MDH, records, equipment, addresses, property owners, residents, and employees
Radon System Tags and Post-Mitigation Checklist
All non-residential mitigation systems installed by professionals must have a MDH issued tag. Licensed mitigation companies or sole proprietor can purchase tags. A mitigation professional must complete a post-mitigation checklist upon completion of the system installation, using the form available by MDH. The system tag must be attached by a licensed mitigation professional in the interior of building, next to the system pressure gauge, in a visible location and on the date of project completion.
