Radon Testing

The City of St. John’s took part in Health Canada’s Take Action on Radon Program in November of 2024. Roughly 345 test kits were distributed to residents to test radon levels in their homes. 278 homes participated by testing for radon gas during the winter of 2024-2025 using 91-day alpha track tests. This represents approximately 1% of the community dwellings with 10% of homes testing above Health Canada’s guideline of 200 Bq/m³.

What is radon?

Radon is a naturally occurring gas that enters homes through contact with the ground. When radon builds up to elevated levels, exposure can increase the risk of developing lung cancer. The only way to determine radon levels is through testing.
