Certification of radiation devices or Class II prescribed equipment

The Canadian Nuclear Safety Commission (CNSC) has updated its guide RegDoc-1.5.1 on the certification of radiation devices or Class II prescribed equipment.

The guide is intended to help applicants to prepare and submit applications to the CNSC for certification of radiation devices and Class II prescribed equipment. It assists applicants and licensees in complying with the Nuclear Safety and Control Act and regulations and ensures that:

  • the radiation device or Class II prescribed equipment, once certified, is safe to use
  • adequate measures are in place to protect the environment, the health and safety of persons, and national security the design meets Canada’s international obligations.

Certified Radiation Devices
The Canadian Nuclear Safety Commission (CNSC) regulates the use of nuclear energy and materials to protect the health, safety and security of Canadians and the environment; and to respect Canada’s international commitments on the peaceful use of nuclear energy.

The Nuclear Safety and Control Act empowers the CNSC to certify the use of radiation devices. The Nuclear Substances and Radiation Devices Regulations stipulate regulatory requirements for certification. Examples of radiation devices that require certification by the CNSC include smoke detectors, fixed and portable nuclear gauges, emergency lighting, and radiography equipment.

A certificate issued by the CNSC for a device applies to a specific model design with precise operating conditions only. Any future changes to the design or use may require recertification of the radiation device.
