The following 93 federal ridings are estimated to have greater than 10% of homes with above-guideline radon levels Those MPs names in bold and marked with * are sixteen ridings estimated to have more than 20% of homes above the federal guideline.
These estimates are based upon results from Health Canada’s Cross-Canada Survey of Radon Concentrations in Homes. This survey found approximately 7% of homes in Canada with radon levels above the federal guideline of 200 becquerels per cubic metre (Bq/m3) and some areas of Canada with higher concentrations. We have mapped these data, reported according to regional health districts, onto federal riding boundaries.
