Health Canada has begun development of national and provincial radon standards to support national reductions to the radon threshold from 800 to 200 Bq/m3 (20 to 5 pCi/L).
According to Health Canada, exposure to high levels of radon increases the risk of developing lung cancer. This relationship has prompted concern that radon levels in some Canadian homes may pose a health risk.
Health Canada has taken a number of steps to protect Canadians from the potential dangers of radon gas. These include evaluating measurement techniques, conducting research into effects of radon exposure and developing guidelines.
Health Canada is collecting feedback on the proposed new guideline from interested stakeholders and the general public. A final report on the consultations and recommended guideline will follow.
