Question 1

Is a short-term radon test useful when buying in Orleans?

Accepted Answer

Health Canada is clear on this: short-term measurements are not appropriate for informing mitigation decisions, and the minimum test length for a valid estimate is 91 days, with those days falling during the heating season. So a short-term test cannot give you a reliable answer for a purchase decision. That 91-day minimum matters a great deal in a purchase. A test started during a condition period will not finish inside it unless the condition runs longer than three months.

Question 2

Can I test for radon during a conditional offer in Ottawa?

Accepted Answer

Not for a valid result. Health Canada says the minimum test length is 91 days for a valid estimate, with at least 91 days of the test during the heating season, and that short-term measurements are not appropriate for informing mitigation decisions. A test started during a condition period will not finish inside it unless the condition runs longer than three months. So a short reading cannot serve as a pass or fail for the purchase.

Question 3

Health Canada on testing a brand-new Riverside South home for radon?

Accepted Answer

Health Canada recommends that every home be tested, no matter where it is located, the type of building, or whether it already has a mitigation system, so a brand-new home in Riverside South is included. Its testing guide applies to a new home the same way: - The minimum test length is 91 days for a valid estimate, with at least 91 days of the test during the heating season. - Test in a normal occupancy area of the lowest lived-in level, a space someone spends more than 4 hours a day in.

Question 4

Where should a radon detector go in a Nepean house?

Accepted Answer

Health Canada says all measurements should be made in a normal occupancy area of the lowest lived-in level of the home. A normal occupancy area is any space in which a person spends more than 4 hours per day. In a Nepean house, that means the lowest level where someone actually spends that time. Health Canada's testing guide sets out the rest: - The minimum test length is 91 days for a valid estimate, with at least 91 days of the test during the heating season.
