Why your home needs to be tested:

Radon gas is the leading cause of lung cancer in non smokers, and the second leading cause in smokers. Because Radon is an odourless and colourless gas, many Albertans are not aware that it is accumulating in their homes. Once the gas enters your lungs, it causes DNA mutations that lead to cancer. 1 in 8 Albertan homes tested over 200 Bq/m3, currently Canada’s maximum acceptable radon-included cancer risk limit. Having your home tested is the only way to determine the risk to you and your loved ones from radon gas.

Our Research:

Many Albertans have already tested their homes and the results from our 2013-16 radon testing study are now available. Learn more.

Our Researchers:


Aaron Goodarzi & Fintan Stanley

Aaron Goodarzi, PhD, is a globally recognized researcher in the field of DNA damage repair, has made breakthroughs in understanding how DNA damage can cause and predict cancer. Fintan Stanley, BSc, is a senior doctoral student in Dr. Goodarzi’s lab, and was the lead author on the recently published “Comprehensive Survey of household radon gas levels and risk factors in Southern Alberta”. Both Aaron and Fintan are public advocates for residential testing of radon gas and are currently leading a campaign to test tens of thousands of homes across Alberta for radon, a Class I carcinogen that is a leading cause of terminal lung cancer in non-smokers.

Important: Neither Aaron Goodarzi nor Fintan Stanley have any financial (or otherwise) connections to commercial radon testing or mitigation product companies, and explicitly declare no conflict of interest in conducting this study.

Did You Know:

Radon is a colourless, odourless gas that is produced naturally from the radioactive decay of underground uranium minerals and is often drawn up and concentrated inside our homes.

To be reliable and accurate, a radon test device – which is smaller than a hockey puck and requires no electricity – must be placed inside a home for 90 days.

Inhaled radon will precipitate as solid radioactive polonium and become trapped in our lungs where it will continue emitting dangerous alpha radiation for decades

Canadian Prairie Provinces have high levels of radon. This is due to the high amounts of uranium, thorium and radium found in our soil.

Radon exposure is 100% preventable. If your home tests high, there are effective mitigation steps you can take to permanently fix the problem.

Radon was discovered by Canadian, Ernst Rutherford, at McGill Univeristy.

A detectable increase in relative lifetime risk of lung cancer is evident at concentrations of 100 Bq/m3 and over.

Exposure to radon during infancy and childhood is more severe in terms of lifetime lung cancer risk because kid’s lungs are little, and so have respiratory rates are 2-3 times greater than adults.

Janet’s Story

“Five years ago I was diagnosed with lung cancer. It was a huge shock. Like most people, I thought only people who smoked got lung cancer. But that’s not the case.”
