What is radon?

Radon is an odourless, radioactive gas formed from the breakdown of uranium. It has no odour, colour or taste.

Exposure to high levels of radium over a lifetime results in an increased risk of developing lung cancer, especially if the person who is exposed is a smoker.

Radon is found naturally in the environment and is common in New Brunswick. It moves freely through the soil and can seep into buildings through cracks in foundation walls and floors or gaps around pipes and cables.

In a poorly ventilated space, radon can accumulate to high levels and can be addressed by improving a building’s ventilation and closing entry points.

The current Canadian guideline for radon in indoor air for dwellings is 200 Becquerels per cubic metre (200 Bq/m3). Please refer to the frequency asked questions or links provided for more information on the radon.
