Radon in Newfoundland public housing a reminder of urgent national problem: experts
The housing corporation found 23 units above federal radon guidelines and has begun mitigation work, while experts urge mandatory testing rules for landlords.
The Newfoundland and Labrador Housing Corp. identified hazardous radon in 23 of 172 public housing units during a 2023 pilot program, with readings ranging from 206 to 448 becquerels per cubic metre.
Following the discovery, the corporation posted tenders last month for mitigation contractors; as of late May, 11 homes had systems installed with work underway in four others.
Health Canada links radon exposure to 16 per cent of lung cancers in Canada, causing about 3,200 deaths annually, and recommends remediation for levels exceeding 200 becquerels per cubic metre.
Jacqueline Wilson, a lawyer with the Canadian Environmental Law Association, argues provinces must mandate testing and introduce laws requiring landlords to mitigate radon risks in rental housing.
Provincial testing strategies remain inconsistent; Quebec and Saskatchewan have systematic efforts underway, while Manitoba ended its program in 2021, reflecting the lack of unified national standards.
