Radon Gas

C5 Plus Ltd. determines radon concentrations using E-Perms which are “electret ion chambers”. Each is placed at breathing zone level and left for a time period of at least one week. The measurements are then analysed and a final report, summarizing the findings and comparing them with Health Canada Regulations, is prepared.

Health Canada has taken on the responsibility of protecting Canadians from the potential dangers of radon gas. Based upon the best available scientific evidence and with the participation of the provinces and territories, Health Canada developed a guideline which was approved by the federal and provincial ministers of health. This guideline recommends that remedial action be taken when the level of radon in a home is found to exceed 800 Becquerels per cubic meter (Bq/m3) as the annual average concentration in a normal living area.

Recent scientific evidence has shown that there is a measurable risk of lung cancer at radon concentrations as low as 100 Bq/m3. As a consequence Health Canada has proposed that the current guideline for radon in indoor air be reduced from 800 to 200 Bq/m3. At a recent meeting of the Federal Provincial Territorial Radiation Protection Committee the revised guideline was unanimously accepted.
