The Canadian – National Radon Proficiency Program (C-NRPP) is a certification program that establishes guidelines, training and resources for the provision of radon services by professionals.

C-NRPP certified professionals are to reflect high standards and ethics in their work, and comply with recognized standards of practice to protect public health and safety. They communicate clearly and accurately with consumers about their process and the harmful effects of radon gas. The C-NRPP’s training programs and resources enable certified professionals to provide quality service as they measure and reduce radon levels in living and working environments.

Certification levels include:

  • Radon Measurement Professional
  • Radon Mitigation Professional
  • Radon Analytical Laboratory
  • Radon Trainer
  • Controlling Radon in New Canadian Homes (CRNCH) Installer
  • CRNCH Inspector

The C-NRPP was established in 2014 as an agreement between the Canadian Association of Radon Scientists and Technologists (CARST) and Health Canada to fulfill the need for a certification program with established guidelines for Canadian radon professionals. Today, C-NRPP continues to work closely with CARST and Health Canada to develop and uphold high standards of practice in the industry, support various organizations involved in radon, and increase awareness of radon effects, detection and mitigation.
