Is there any proof that Radon causes lung cancer?

As with most illnesses, cause and effect can not be 100 percent proved. If you have high blood pressure and suffer a stroke, studies indicate that your high blood pressure is the most likely cause.

I don’t live in an area with any known high Radon levels, should I still complete a Radon test?

Even homes in areas considered at low risk for radon could have high radon levels. Although there have been no “absolutely safe levels of radon” determined; by following Health Canada’s guideline of 200 Bq/m³ or 5.4 pCi/L, the EPA recommendation of 148 Bq/m³ or 4 pCi/L or the World Health Organization’s recommended level of 100 …

How does Radon get into my home?

The air pressure inside a building is usually lower than in the soil surrounding the foundation. This draws in gases, including Radon, through openings in the foundation where it is in contact with the ground. This includes construction joints, gaps around service pipes and support posts, floor drains and sumps, cracks in foundation walls and …
