As per our previous communication in November 2014, the York Catholic District School Board passed a motion at its Regular Meeting of the Board to initiate Radon testing in all York Catholic District School Board buildings. Alpha Track Radon sampling devices were placed in all schools and at the Board’s head office, the Catholic Education Centre. This initiative was a positive and proactive measure, underscoring the Board’s commitment to the safety and well-being of all students and staff.
To complete this work, the Board partnered with a consulting firm that has expertise in Radon testing. The results of the Radon samples have been received, and all samples registered are well below the level at which Health Canada has established for remedial action, which is 200 Bq/m3. In addition, the Board consultant noted that “all samples registered are well below the most stringent level for action of recommendations from the World Health Organization.” In summary, the results indicate that no further action is required at this time.
