In 2007 Health Canada established a health guideline of 200 Bq/m3, above which action is recommended to reduce occupant exposure levels. The SSBC Radon Testing Project will begin in a sample of government owned and leased residential and commercial buildings to test for radon and to determine any requirement for mitigation.
SSBC is part of the BC Ministry of Technology, Innovation, and Citizens’ Services. Under the Real Property Division, SSBC is responsible for owned, managed and leased government facilities across British Columbia.?
The SSBC Radon Testing Project will be completed in at least one building from each of the following communities:
- Alexis Creek
- Anahim Lake
- Bella Bella
- Bella Coola
- Port Clements
- Queen Charlotte
- Williams Lake ?
The BC Lung Association is keeping key representatives informed of the SSBC Radon Testing Project. Every Municipality, Regional District, and local Member of the Legislative Assembly from within the communities with at least one building being tested have been sent a project information letter:
Buildings for the SSBC Radon Testing Project were not selected based on any known risk; rather, the project aimed to include a mix of building types in order to evaluate best practices in radon testing and mitigation processes. Radon can be found in all regions of the province and can make its way into any building where the foundation comes into contact with the soil.
- ?Results are posted below that indicate the following:
?Please note: all buildings that test above the Health Canada guideline of 200 Bq/m3 will be mitigated to protect occupant health and safety.??The following project documents are available for review:
- Postal code tested
- Number of buildings that tested above the Health Canada guideline of 200 Bq/m3?
- Number of buildings that tested below the Health Canada guideline of 200 Bq/m3?
Radon has been shown to cause lung cancer over many years of exposure and is estimated to be the second leading cause of lung cancer, after smoking. The only known health impact from radon exposure is lung cancer.
Radon is a colourless, odourless, tasteless gas produced by the radioactive decay of naturally occurring uranium. Uranium-bearing rocks and soils decay into radon gas, which migrates from underground to the surface of the earth where it is normally diluted with fresh air to very low concentrations. However, radon can also find its way into any building where the foundation is in direct contact with the soil. Indoors, radon can get trapped and accumulate to much higher concentrations. The only way to know if a building has high levels of radon is to test.
