Radon: For professionals

Health professionals

Radon is the number one cause of lung cancer for non-smokers. Epidemiological studies confirm that there is a risk of radon-induced lung cancer from indoor radon levels found in homes and public buildings across Canada. Health professionals are a respected and trusted voice, so encourage your patients to take action to reduce their radon exposure.

Your patients may ask you about the health risks of radon and the need to test their homes. McMaster University’s MacHealth has developed an accredited continuing professional development course to help you answer questions and provide guidance.
