Radon is a carcinogenic, radioactive gas created from the decay of uranium in minerals present in rock, soil and water. Indoors it is not naturally-occurring but enters the indoor environment and contact with people as a result of the way homes, schools and workplaces are designed, constructed and maintained.
You cannot see, smell or taste radon. It is extremely radioactive, emitting alpha radiation as it decays. Once inside the lungs, delicate tissues can be genetically damaged by radon decay products, and this can lead to the development of lung cancer.
Radon is one of the most significant environmental health risks today, responsible for an estimated 3,200 deaths every year in Canada. Living in a home with elevated levels of radon is very dangerous. Recent estimates published by the Radiation Protection Bureau of Health Canada show that 16% of lung cancer deaths are attributable to indoor radon exposure. This estimate is conservative and will increase as radon induced lung cancers are more commonly detected in the future.
Our Inspectors are fully trained professionals, certified, and all test results are sent to an independent, Canadian-NRPP certified laboratory for full analysis.
Tarion has clarified the impact that radon issues would have on a home’s warranty coverage. If radon is found in a home in significant amounts, it will be covered by Tarion. To assist Tarion employees in making consistent warranty decisions related to radon gas, a guideline has been developed when dealing with a potential radon-related claim. The reported defect must be that radon gas is in excess of Health Canada’s acceptable levels of 200 Bq/m3, in order
for it to be covered by Tarion. These guidelines account for the Ontario Building Code requirements for radon and soil gas control.
