Radon Certification Courses

The Canadian National Radon Training Centre (CNRTC), a division of Radon West Ltd. is pleased to offer Canadian specific Radon Measurement and Mitigation certification courses. The mitigation course includes distance-based mitigation mentorship for our first system install.  

Both courses are approved for certification by Canada’s radon certification body, the Canadian National Radon Proficiency Program (C-NRPP).

In-class Reviews

Do you value an in-class learning environment but prefer not to miss a week of work for training? Maybe our hybrid instruction can help you by providing the benefits of learning at your own pace while also giving you the advantages of an instructor led review.

Stand-alone mitigation mentorship

Feedback on the distance-based mitigation mentorship is that it was invaluable for anyone entering the radon mitigation industry.  If you want to brush up on your existing skills, moved to an area where the mitigation conditions are different than what you are used to, or you were certified early on before this program was put in place this course will likely be of interest to you.

Exam Process

1. Pass a C-NRPP Entry Level Radon Measurement and/or Radon Mitigation Exam

Exams must be written in person under the supervision of a proctor. If you are taking a classroom course, a proctor may or may not be included as part of your course. If you are taking a distance-based course, you will need to arrange for a proctor to oversee your exam. These arrangements are to be made by the examinee, and then you will need to order the exam from C-NRPP. More information is available through  the C-NRPP Exam Coordinator (contact information above).  

IMPORTANT: Download and review this document which includes important information regarding proctored exams, time limits, certification, etc.


Take your time and make sure that you go over all of the online chapter quiz questions. Repeating the quizzes is a great way to study for the C-NRPP exam.  

Once your exam results are available, they will be posted online here and detailed results will be mailed to the address provided at the time of the exam.

Carefully review the following 3 Health Canada documents:

2. Complete the C-NRPP Application Form

Once the exam has been taken and a passing grade of 70% has been achieved, you must apply to the C-NRPP program for certification.

  • There is a $200 fee associated for the Measurement certification and $200 for the Mitigation certification. This fee is payable at the time of the application.
  • The application takes 2-4 weeks to process.
  • Once completed your certification will be added to the database and appear on the C-NRPP website under Find a Professional
  • The physical certificate(s) and ID cards will be mailed to you. (This can take two weeks to receive).

3. Certifications are valid for two-year cycles.

Professionals must complete 20 credit hours of Continuing Education within every two-year cycle and submit course certificates as well as supporting device proficiency/calibration documentation upon renewal.

4. Additional Requirements for Analytical Providers.

If you are going to be analyzing your own radon measurements, you will need to submit Performance Test documents and annual Calibration Certificates for each type of device that you use. For example, if you use a CRM and the E-perm system you will need to complete performance testing (once per company) and (typically) annual calibrations for each device.

With this certification, you may analyze specific measurement devices on behalf of your clients but not for other radon measurement professionals.

Alpha track detectors are analysed by a separate lab, so performance testing is not required for this type of device. Also, CRM’s that are leased and analysed by a third party would not require a performance test. Typically, performance testing would apply to CRM’s that you analyse, as well as the E-Perm system, sniffers, grab samplers etc.
