Thank you for your interest in testing with Evict Radon

Evict Radon is a Canadian non-profit organization dedicated to solving Canada’s significant and worsening radon-gas exposure problem. Radon is a substantial cause of lung cancer even in non-smokers. By testing your home with one of our non-profit, research-grade radon test kits and enrolling in our national, public university-based research study, you are helping Evict Radon-aligned researchers from across Canada to understand radon exposure and develop new ways to protect ourselves and loved ones.

Common practice states that winter is the optimal time to radon test. However, as we collect more data, we have determined little difference between winter and spring radon testing. We do, however, encourage our participants to test over seasonal change. At this time, the best and most accurate radon readings obtained during the spring and summer months are those that are longer than 6 months.

Evict Radon is a volunteer-led non-profit organization that combines grassroots science engagement and citizen science-based research in a way perhaps never seen before in Canada for preventing cancers. Evict Radon is led by Dr. Aaron Goodarzi of the University of Calgary, who is the federally-appointed Canada Research Chair for Radiation Exposure Disease.

All of our volunteer efforts and funding are designed to encourage as many Canadians to test their home for radon through our National Evict Radon research study. Everything we do strictly adheres to national research ethics standards, as well as best practices for controlled studies that will pass academic peer-review and, ultimately, very close scrutiny from the public and experts. Achieving a radon risk-free future for Canada is very possible and, if successful, prevent literally thousands of new, mostly high lethality lung cancers each year.
