RADON AND PHASE 1 ESA ENVIRONMENTAL SITE ASSESSMENTS
What you need to know about Radon!
Radon is a naturally occurring, odorless, colourless, radioactive gas that comes from the ground, and is also found across Canada. Long-term exposure to high levels of radon increases the risk of developing lung cancer. According to Health Canada, 16% of lung cancer deaths are related to radon.
Lifetime excess cancer risk estimates for indoor air carcinogens show that radon gas is the highest priority exposure in Canadian settings. It exceeds risks from asbestos.
If you are conducting PHASE 1 Environmental Site Assessments, you should consider radon. We have provided some sample wordings for you to use.

Radon testing requires a 91-day minimum testing period during the heating season (October through April). In cases where such testing may not be practical, the prospective purchaser and lender should consider testing the building(s) as prescribed by the Canadian Association of Radon Scientists and Technologists (CARST) Real Estate Testing Guideline in order to make timely and informed decisions.
