Radon causes 1,900 deaths a year in homes; building codes commission looking into making stricter requirements

Proposed changes to the National Building Code of Canada are going up for public review between September 29 and November 28 this year. Watch www.nationalcodes.ca for a link to the instructions on how to submit comments.
The Canadian Commission on Building and Fire Codes has also set up a task group reviewing current requirements in Part 5 and Part 9 of the National Building Code for protecting building occupants from the ingress of radon.
Health Canada estimates that radon in homes is responsible for 1,900 deaths a year in Canada. The government department has made its guideline more stringent by reducing the acceptable indoor concentration of radon in homes from 800 Bq (becquerels) per cubic metre (Bq/m3) to 200 Bq/m3.
