Mr Radon – Southern Ontario

Health Canada recommends that everyone test their homes for lung cancer causing radon gas. In London it is important to conduct a radon test of your home and have a radon mitigation system installed should your levels be high. There are three different guidance’s for a mitigation decision. Health Canada says we should stay below 200 Bq/m3. The EPA says 148 Bq/m3 or that U.S. citizens should be concerned when a home is between 74 and 148 Bq/m3. The World Health Organization’s reference level is below 100 Bq/m3. Health Canada’s cross Canada survey concluded that 7% of all homes are exposed to elevated levels of radon above 200 Bq/m3. You may be part of that percentage in London. All homes (old and new, large and small) have the possibility of being high in radon. A neighbour’s low test result does not mean that your home is at low levels. Reduce your risk level in London by conducting a radon test.
