However, in that survey ONLY 109 HOUSES WERE TESTED in London and Middlesex county ! Not a lot of homes (out of 195, 679 residential houses according to 2011 statistics) in a large area (over 3,300 km2) on which to base your survey data !! That's testing 1 out of every 1800 houses!!! Don't be fooled into complacency - your home could easily be over the limit, as mine was, but no one surveyed me. GET TESTED TODAY. I have found in my testing in London-Middlesex, that the actual percentage of homes that are above Health Canada's limit is closer to 20%, not 2% (2015-2021) as Health Canada suggests ! You and your family will never know if you are at risk without a test. In recent testing (2017-2019), I have found four houses on one short crescent that were over 200 Bq/m3 (Health Canada's limit) !! One concerned citizen phoned me recently about mitigation because all homes (six) on her small cul-de-sac were over Health Canada's limits !!
