An odourless, cancer-causing gas is building up in many Canadian homes. A ����ɫ�� radon research team, fuelled by renewed funding from the Alberta Real Estate Foundation (AREF) to the campaign, is working to change this —��owning cancer through prevention and partnership.

Radioactive radon gas inhalation is the leading cause of lung cancer in non-smokers, responsible for about 88,000 cases of lung cancer in Canada since 2001. Radon is produced in the ground and normally it dilutes to virtually nothing in outside air, but our modern homes, schools and workplaces are capturing and concentrating radon to unnaturally high and cancer-causing levels in indoor air.

With concerning in-home radon exposure trends found across every Canadian province and territory, the radon research team is currently working with multiple government groups toward the inclusion of proactive radon mitigation systems in all new residential properties constructed using the 2025 Building Code.

Leading the charge is ����ɫ�� Aaron Goodarzi, PhD, Canada Research Chair for Radiation Exposure Disease and an associate professor in the Cumming School of Medicine (CSM). His work to is bolstered by partnerships, including a strong one with AREF, which has committed $975,000 in total to this life-saving research since 2017. A recent commitment of $325,000 to OWN.CANCER is furthering this work.

“Now that the Evict Radon is more than five years mature, we’re in the position — thanks to the new gift from AREF — to really make a difference to how certain key stakeholders are operating, including the real estate community. Home inspectors are next on our list to engage with on this specific issue. This is one of the changemaker opportunities we have with the new funding," Dr. Goodarzi says.

"Exposure to radon, which is radioactive and DNA-damaging, is overwhelmingly something that happens within the residential built environment and is avoidable,” says AREF Executive Director Patti Morris. “This project is an excellent fit with our mandate with a focus on consumer protection and healthy homes.”

Recent discoveries and success

This past September, Goodarzi, along with Joshua Taron,��the associate dean (research and innovation) at the ����ɫ��,��and a multidisciplinary team of UCalgary cancer researchers and architects, proved that average radon gas levels in new homes in Canada are 467 per cent higher than in Sweden.

Since 1980, radon levels have consistently risen in Canada, while falling in Sweden. The causes of the changes in both countries are complex, with no single decision or event responsible for the increase.

Another 2021 publication by Goodarzi and team showed how age, gender and profession significantly impacted how quickly people learning about radon risk pursued testing in their homes. Women and health-care professionals were more likely to act quickly, while engineers, geoscientists and realtors were less likely — leaving them exposed to radon longer and increasing their risk for lung cancer.

The team is working with Dr. Linda Carlson, PhD, the Enbridge Research Chair in Psychosocial Oncology and a professor at CSM, to tease out why. With the new AREF gift, the team will aim to��better target the way it communicates radon risk for more diverse genders and professional backgrounds.

OWNing cancer

AREF’s gift to the OWN.CANCER campaign, which will continue to support UCalgary radon research when it moves to the new Calgary Cancer Centre in 2023, brings Goodarzi and the interdisciplinary team of Evict Radon scientists another step closer to their goal of making Canadian homes safe from radon.

"Owning cancer to me is about preventing hundreds of thousands of future cancers that might arise in today’s children, tomorrow, by understanding toxic cancer-causing exposures in our environment,” Goodarzi says. “We’ll never have to deal with it in the first place if we put into place the systematic things that can prevent it."

Morris strongly agrees. “Actual prevention requires concerted action in terms of knowledge generation, knowledge implementation, and effective education and communication across sectors. In my mind, this project embodies the ideals of OWNing cancer.”

In addition to supporting research on radon awareness and promoting radon education in the real estate industry, AREF has funded a variety of projects across many faculties within the university — most recently at the and the .
