Radon Protocols

Canadian Guideline for Exposure to Radon in Indoor Air, June 2007

In March 2006, the Radon Working Group of the Federal Provincial Territorial Radiation Protection Committee proposed the following radon guidelines:

• Remedial measures should be undertaken in a dwelling whenever the average annual radon concentration exceeds 200 Bq/m³.
  
  

• The higher the radon concentration, the sooner remedial measures should be undertaken.
  
  

• When remedial action is taken, the radon level should be reduced to a value as low as practicable.
  
  

• The construction of new dwellings should employ techniques that will minimize radon entry and will facilitate post-construction radon removal, should this subsequently prove necessary.
  
  These recommendations have resulted in the current Canadian radon guideline of 200 Bq/m³

E-PERM detectors are the ideal screening method for determining whether remedial action is required, in accordance with Canadian radon measurement guidelines.

The WHO has issued a comprehensive booklet on the hazards of indoor radon.

"To limit the risk to individuals a national reference level of 100 Bq/m³ is recommended.
