Licensing for Radon Measurement Professionals - EH: Minnesota Department of Health

Licensing for Radon Measurement Professionals

Who needs a license?

Any person who performs a test to determine the presence and concentration of radon in a building the person does not own or lease. This includes anyone who places or retrieves test devices.

What do you need to get licensed?

Training

To be eligible for a measurement professional license, all applicants must:

  • Complete an initial radon measurement training course
  • Pass a radon measurement examination

Approved courses and exams:

Here are some upcoming classroom training courses offered in Minnesota that we have been informed of:

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.

Application and Cost

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 completed online application form through the radon licensing system
  • Proof they have completed the required training and passed the measurement exam
  • A list of measurement devices they plan to use
  • A copy of their QA plan
  • A nonrefundable fee of $150 payable by e-check, credit card, or debit card

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 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.

Reporting Requirements

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:

  • Address of testing location
  • Start and end date of test
  • Type of device used
  • If the test was an initial, follow-up, or post-mitigation test
  • If the test was part of a real estate transaction
  • Reported radon concentration
  • Age and type of building tested
  • Whether a mitigation system was present and the system tag number (if applicable)

All data can be entered into a spreadsheet and uploaded as a .csv file (template is available online) or entered individually.

Standards of Conduct and Work Practices

Radon measurement 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 measurements in homes, multifamily buildings, and schools/large commercial buildings ¬†
  • Make available, to MDH, records, equipment, addresses, property owners and residents, and employees
