Radon gas, a naturally occurring radioactive gas, poses significant health risks to Canadians. Is radon gas dangerous?
1. Health Impact: Radon is the 2nd leading cause of lung cancer in Canada, If you smoke and are living in a home with a high level of radon, you are at an even higher risk for lung cancer. Canadian Lung Association https://www.lung.ca/radon
2. Prevalence: Radon levels vary across Canada due to geological factors, but elevated levels have been found in homes and buildings in every province and territory. Certain regions, such as Southern Ontario, are prone to high radon levels due to the presence of uranium-rich bedrock.
3. Indoor Exposure: Radon enters buildings through foundation cracks, gaps in floors, walls, and other entry points. Once inside, it can accumulate to dangerous levels, especially in basements and lower levels where ventilation is limited. Since radon is odourless, tasteless, and invisible, testing is the only way to detect its presence.
4. Risk Mitigation: Testing homes for radon is relatively simple and inexpensive. Health Canada recommends that all Canadians test their homes for radon. If levels are elevated, steps can be taken to reduce radon levels such as installing a radon mitigation system.
5. Regulatory Measures: In recent years, there has been increasing awareness and action regarding radon gas in Canada. Some provinces require mandatory radon testing and mitigation measures for new construction. National guidelines and standards have been developed to address radon exposure in existing buildings.
