Providing radon gas awareness

What is radon gas?

Radon gas is the second leading cause of lung cancer after smoking. Radon is a naturally occurring gas found in the ground throughout the world. Most homes that are in contact with the ground will contain some amount of radon gas. Radon becomes more of a concern when it reaches high levels.

How common are high levels of radon gas? 

According to Health Canada about seven per cent of the Canadian homes have radon levels that may be putting residents at risk. The geology within the BC interior favours radon, and we have some “hot spot” areas with high radon levels in approximately 40 per cent of homes.

How does radon get into a home?

Radon accumulates in low lying areas like basements.  Radon can enter a home through normal construction seams or cracks in the foundation or dirt floor such as older crawl spaces. It can also enter a home through the ventilation system. 

Am I at risk?

Radon gas is colourless, odourless and tasteless, so the only way to know if the radon levels in your home are high is to have it tested. 

How do I test my home?

The best time to test your home for radon gas is November through April. Testing a home is easy and inexpensive. Testing involves placing a small puck-like kit within the lowest area of the home that could be occupied for more than four hours per day. The kit should remain in that location for a minimum of three months and then mailed to a laboratory for results.
