Radon In residential dwellings and public buildings

Radon is a radioactive gas that is formed naturally by the radioactive breakdown of uranium in soil, rock and water.

When radon escapes from the ground and mixes with outdoor air, the resulting concentration is too low to be of concern.... but what if it enters a building?

How does radon enter your home?
When radon enters an enclosed space such as a building, the gas can accumulate to higher levels. Exposure to radon leads to an increased risk of lung cancer. The level of risk depends on the concentration of radon and the length of exposure.

The current Canadian guideline for radon in indoor residential air is 200 Becquerels per cubic metre (Health Canada). The only way to be sure of the radon concentration is to test.

Contact a radon measurement professional to test for radon in your home or building.
