Testing and mitigation in social housing

Kingston, Ontario

In Kingston, Ontario, the local health authority (KFL&A Public Health) approached the City of Kingston and housing providers concerning testing social housing units, as part of broader radon testing initiatives. KFL&A Public Health organized the testing of the units, including hiring staff to place and pick up the detectors, and the City offered to pay the cost of radon mitigation.

KFL&A staff used a sampling strategy focusing on ground floor and basement units. They sampled 1135 units leading to 923 detectors being analyzed (212 detectors were lost to follow-up). Of the 923 detectors analyzed, 27 were above HC's limit of 200 Bq/m3. As of publication, 18 of 27 have been mitigated.
