Radon monitoring in Yukon schools

Government of Yukon response to radon

In September 2017, the Government of Yukon finalized the Radon Management Guideline, which is a unified approach to radon testing, monitoring and, where necessary, remediation in all government buildings, including schools. We will follow these practices to test radon levels in schools, and will remediate schools as needed to ensure radon levels are within the range recommended by Health Canada.

Prior to the development of these guidelines, we monitored radon levels in all Yukon schools during the 2016/17 school year following Health Canada’s guidelines for Indoor Air Quality. 

Health Canada’s recommended levels of radon concentration for acceptable indoor air quality are as follows:

  • Below 200 Bq/m3*– acceptable
  • Between 200 Bq/m3 and 600 Bq/m3 – remediate within 2 years
  • Above 600 Bq/m3 – remediate within 1 year

*Bq/m3 =Becquerel per cubic metre

It is important for you to check the radon levels in your home, too. You can get radon test kits from your local hardware store. To learn more, visit the Yukon Housing Corporation.

2016/17 radon monitoring results from schools

In the 2016/17 school year, radon monitoring devices were placed in Yukon schools. The results of this monitoring are as follows:

According to Health Canada’s Guidelines for Indoor Air Quality, results for Jack Hulland Elementary, Nelnah Bessie John and the Teen Parent Centre indicate these schools must be remediated within two years. Radon levels at Holy Family Elementary were also near Health Canada's recommended levels and will be remediated.

In fall 2017, we completed remediation work at Nelnah Bessie John. We expect remediation work to be completed at Jack Hulland Elementary School in late 2017, Holy Family Elementary in late 2017/early 2018 and the Teen Parent Centre in January 2018.

Results for all other schools fell below Health Canada’s guidelines. During winter 2017/18, between the heating season of October to April, we will test all Yukon schools following the new Radon Management Guideline. Testing will take place over a minimum of 3 months and will be completed or guided by a certified radon measurement professional. If required, further remediation will then be done on any school that tests above levels recommended by Health Canada.

About radon

Radon is a colourless, odorless, naturally occurring gas in Yukon. It can enter buildings through cracks and unsealed openings in basements and foundations from the soil.

Radon does not pose an immediate danger to health and is only a concern if there is prolonged exposure to high concentrations over many years.
