Radon Testing in Federal Buildings - Highlights

In late 2007 Health Canada began testing radon levels in federal buildings. The purpose of this project is to identify federal workplaces with radon levels above the Canadian Radon Guideline of 200 Bq/m3. This will allow federal employers and building managers to address the need for remediation, should it be necessary.

Health Canada provides the radon detectors and instructions on where to place them as well as the laboratory analysis and results. Each individual department or building manager is responsible for deploying detectors in the buildings and sending them back to Health Canadaĺs National Radon Laboratory for analysis. All radon tests are conducted using long-term (3-month) radon detectors.

Following is a breakdown of the Federal Building radon test results as of November 2013.
Total number of Buildings 12865
Number of Buildings with average Radon below 200 Bq/m3 12371
Number of Buildings with average Radon between 200 and 600 Bq/m3 426
Number of Buildings with average Radon above 600 Bq/m3 68

As of November 2013 approximately 3.8% of the federal buildings tested have average radon concentrations above the Canadian Guideline.

Canadian federal building owners or facility managers are welcome to contact Health Canada for information on radon testing at 613-948-1369 or radon@hc-sc.gc.ca.

Health Canada is working in partnership with a number of organizations to raise awareness about the risks from radon including the Next link will take you to another Web site Canadian Lung Association, Next link will take you to another Web site Canadian Cancer Society, Next link will take you to another Web site Canadian Medical Association, and the Next link will take you to another Web site Canadian Partnership on Children's Health and Environment.

Health Canada has developed a number of resources including brochures, facstsheets and guides to help Canadians learn about radon and how to protect themselves and their family by testing and reducing the level, if necessary.
