Radon is an odourless, tasteless, colourless radioactive gas that is the by-product of uranium decay. Uranium occurs naturally in soil and rock formations, and places with higher than normal uranium deposits, such as Alberta and Saskatchewan, have higher radon levels.
Radon seeps through the earth and into basements, where it can become trapped because of the efficient way our homes are sealed from the outside elements.
Prolonged exposure to radon can lead to health problems, including lung cancer. In fact, after smoking, radon gas is the leading cause of lung cancer.

The Alberta Building Code 2014 included new requirements to protect homes from radon. The requirements came into effect in late 2015, and include, among other things, that new homes require a properly located radon rough-in or passive pipe in the basement, which can make it easier (and cheaper) to install a radon mitigation device in the future if it’s needed.
The good news when it comes to radon is it’s a solvable problem. Even if you fall in love with a home that hasn’t had a radon test or the results are high, a radon mitigation device can be installed to vent radon gas outside the home from the basement. Mitigation costs vary, but are often not more than $2,000-$3,000. Hire a Certified Radon Technician to install the device to ensure it’s done properly.
