Requirements:
To be eligible for a measurement professional license, all applicants must:
Complete an approved initial radon measurement training course
Pass an approved radon measurement examination (the course completion exam at the end of an online course is not sufficient)
Contact MDH if you need to take an exam
Approved courses:
- Approved exams:
(If you take an in person class, they may offer the NRPP or NRSB exam after the course)
- NRPP Exam
- NRSB Exam
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 United States Environmental Protection Agency National Radon Proficiency Program Guidance on Quality Assurance. MDH has developed a QA plan template. While you are not required to use the MDH template, it has been developed to make the process as simple as possible. At this time, none of the CRM or passive device manufacturer’s templates meet the necessary requirements. You may modify your existing plan, modify a manufacturer’s plan or start from the MDH template.
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.
