Testing Your Home & Building For Radon
Radon concentrations in our homes & buildings can vary significantly from hour to hour, day to day, and even more so from season to season. As a result, long-term tests are the best way of estimating the annual average radon concentration in your home or building. Long-term radon tests range from 91 days to 1 year in length, and are minimally invasive, taking up no more room than a cup of coffee.
Health Canada recommend radon testing be conducted during the winter heating season (between October and April) for a minimum period of 91 days.
