Red Deer Catholic Regional Schools, in partnership with Radon Care, tested all facilities earlier this year to determine levels of radon gas using "Alpha Track Detectors" and were placed in most rooms for 90-100 days.
Radon gas is a naturally occurring colorless, tasteless and odorless soil gas which occurs from the decay of uranium in soils and rocks. Radon is diluted in outdoor air but can potentially accumulate in buildings through structural entry points such as cracks in concrete foundations to high levels.
Health Canada recommends action for any occupied buildings with levels of radon at or above 200 Bq/m³. We are pleased to let you know that all rooms tested in your school, with the exception of one office, are below the Health Canada Guidelines. A review of the air handling system was conducted over the summer and additional tests will be conducted between September 9 and September 17 to ensure the radon levels are within Health Canada guidelines during occupied times. A summary of these results will be available shortly after the testing is completed.
