The CNSC invites comments on proposed amendments to regulations that protect the public and nuclear energy workers

News release

June 14, 2019 – Ottawa, ON 

The Canadian Nuclear Safety Commission (CNSC) is inviting comments from the public on proposed Regulations Amending Certain Regulations Made Under the Nuclear Safety and Control Act (Radiation Protection).

The CNSC is updating these Regulations to align with the latest international standards for radiation protection and to provide additional regulatory clarity based on its regulatory operational experience.

Key elements of the proposed Regulations include:

  • a new requirement for licensees to inform all nuclear energy workers (NEWs) of their duties and responsibilities during an emergency, as well as the risks associated with radiation during the control of an emergency

  • a new requirement for licensees to make reasonable accommodation for the public and NEWs who have self-disclosed that they are breastfeeding

  • revision of the equivalent dose limits for the lens of the eye

  • clarification of expectations for applying for a licence to operate a dosimetry service, the labelling of containers and devices, and the posting of radiation warning signs

  • a new requirement for licensees to retain dose records for a five-year period

  • a new requirement for licensees to appropriately select, use and maintain radiation detection and measurement instrumentation

The draft Regulations were recently approved by the Governor in Council for consultation. They have been published in the June 15 edition of the Canada Gazette, Part I. Consultation on the proposed regulations is open until July 16, 2019.

To comment on the proposed Regulations, please send feedback to:
