Radon in New Brunswick

A natural occurring radioactive gas, Radon comes from the ground and is produced by the natural breakdown (radioactive decay) of uranium and radium. It is slowly released from the ground, water, and some building materials that contain very small amounts of uranium, such as concrete, bricks, tiles and gyproc. It has no color, odor, or taste.

When radon is released to outdoor air, it is dispersed into the atmosphere and is not a concern. However, in enclosed spaces like houses or other buildings, it can sometimes accumulate to high levels.

How Radon Enters the Home

Radon is a soil gas that can enter a home through any opening that contacts the soil around or underneath the building. It can seep in through cracks or holes in basement floors or walls, including openings for utility connections, and through hollow support posts. If there is radon in the building's water supply, it can also enter the space via running tap water. However, in water it is considered a minor exposure pathway.




  • 2nd Leading cause of lung cancer
  • New Brunswick is a hot spot for Radon
  • 1 in 5 Homes in NB has a Radon Problem



Unit Measurements are in Becquerels (Bqs)

A Becquerel is the quantity of radioactive material in which one nucleus decays per second.

For homes with over 200Bqs – Mitigation is suggested within 1 year.


Interesting fact:

  • 300 Bqs is equivalent of having 1 X-Ray/day
  • 370 Bqs is equivalent of smoking 1 Pack of Cigarettes/day

Mitigation – Reducing Radon in Your Home

If the radon level in your home is above the Canadian guideline of 200 becquerels/metre³, you need to reduce it.  The higher the level in your home, the sooner it needs to be reduced.
