Health Canada Consultation on Proposed Revisions to Safety Code 6

Notice to Stakeholders

Safety Code 6 (SC6), also referred to as Limits of Human Exposure to Radiofrequency Electromagnetic Energy in the Frequency Range from 3 kHz to 300 GHz, is a Health Canada guideline which sets limits for safe human exposure to radiofrequency (RF) electromagnetic fields (EMF).

Health Canada scientists monitor the scientific literature on an ongoing basis and SC6 is periodically updated to take into account recent scientific data from studies carried out worldwide. In demonstration of the Department's commitment to transparency and openness in its decision-making processes, Health Canada is publishing its 2014 proposed revisions to Safety Code 6 for a 60 day comment period to allow public review and input.

The proposed version of Safety Code 6 includes RF limits that are more restrictive than those in the current version of Safety Code 6 (2009). Canada's current exposure limits, even before the review, are consistent with science-based standards used in other parts of the world ( e.g., the United States, the European Union, Japan, Australia, and New Zealand), and Health Canada's 2014 proposed revisions to Safety Code 6 will make Canada's limits among the most conservative science-based limits in the world.á

Health Canada reminds all Canadians that their health is protected from RF energy by the human exposure limits recommended in Safety Code 6. The current Safety Code establishes and maintains a human exposure limit that is far below the threshold for potentially adverse health effects. The limits in the current Safety Code 6 provide protection against all known adverse health effects for all individuals.


Health Canada recognizes the significant stakeholder interest in RF safety. However, only feedback of a scientific nature received during the public consultation period can be considered in the finalization of a revised Safety Code 6.

Interested parties are encouraged to provide comments and suggestions of a scientific nature by July 15, 2014 to:

Information Documents:

Additional information on Safety Code 6 is available on the Health Canada's Radiofrequency Exposure Guidelines webpage, as well as the Next link will take you to another Web site report of the Royal Society of Canada's (RSC) Expert Panel on Safety Code 6 (2013), Understanding Safety Code 6, and For the Record: Health Canada Factsheetá "What is Safety Code 6?"

A detailed scientific rationale supporting proposed changes to the Code is available, upon request. To obtain an electronic copy of this document, please contact note the rationale document is available in English only and is not intended for a general audience due to its highly technical content.

Reporting to Canadians:

Following the consultation and a review of comments received, Health Canada will finalize and publish a revised Safety Code 6, on Health Canada's Radiofrequency Exposure Guidelines Web site, as well as a summary of technical comments received during the consultation. Responses to individual feedback or queries will not be provided.
