Over the last few years I have had the opportunity to test several homes in area’s of Waterloo Region and surrounding. The Radon Content in Waterloo Region and the surrounding area shows consistent with the Ontario map which was supplied by Health Canada. Every home has Radon. The key is the amount of Radon Content in the soils under the homes and building we live and work in.
The threshold limit for Radon according to health Canada is 200Bq/m3. The lowest test I have completed was 27Bq/m3. The highest is well beyond the 200Bq/m3 limit.
Radon is directly related to more than 3200 deaths per year in Canada alone. Of all the tests I have completed, only one falls into the guarded category. The balance fall into the high and elevated areas. The tests should be completed in areas of concrete slab – soil contact, and where people and pets live in these areas for 4 or more hours per day.
