For a healthy home

Radon

RadonRadon (Rn) is a radioactive gas, odourless and colorless of natural origin, present everywhere in the earth's crust. Outside, this gas is released into the atmosphere where its concentration is not a source of concern. However, when radon enters a home, it remains trapped there and can consequently attain levels that present serious health risks. Every home is at risk, even yours!

  • Facts and Figures
    Exposure to radon is the second cause of lung cancer after smoking. In Quebec, it is estimated that 16% of all lung cancers are linked to radon exposure. The regions of particular concern are the Gaspé Peninsula, the Magdalen Islands, the Lower Saint Lawrence, the Chaudière-Appalaches region, Outaouais, Laval, Nunavik and the Laurentians.
  • What can I do to protect myself from radon?
    It is possible to have a test done for the presence of radon gas in one’s home. If levels are above 200 becquerels per cubic meter (Bq/m3), work must be carried out to reduce its concentration.

    For all new construction, it is better to install a passive depressurization column, which is composed of 3 to 4 inches (8 to 10 centimeters) of plastic. This depressurization column goes from under the concrete floor up to the roof. Do not forget to completely seal the hole in the concrete flooring into which the column is embedded in order to avoid any leakage. For a radon test or for more information, contact the Quebec Lung Association..
