'Radon exists everywhere': How to detect and keep the harmful gas out of your home

An invisible, odourless and harmful gas could be making its way into your home.

An invisible, odourless and harmful gas could be making its way into your home.

"Radon is a radioactive gas that comes from the decay of radium," said Andrew Arshinoff, the owner of RadonCare.

"Radon exists everywhere. It's inside, it's outside," he added.

When the gas builds up inside your home is the problem. According to Health Canada, one in five Canadian homes will have high radon levels, no matter the age or type of construction.

"Alberta is one of the highest places in the world," said Arshinoff, "Every neighbourhood in Alberta has at least one home that will test above the guideline."

People can test radon levels themselves. There are a variety of digital meters available, but Arshinoff warns it should be one approved by Health Canada.

"Some digital meters, be very careful if you're looking at those out there. Some are good. Some have been recalled by Health Canada. Make sure you do your research if you're going to pick one of those up," Arshinoff said.
