Radon is an ordourless, colourless, radioactive gas that is formed naturally by the breakdown of uranium in the soil, rock and water.
Uranium is everywhere in Canada, so Radon is everywhere in Canada. Radon is in soil and rock, and travels through rock cracks and soil pore spaces. Radon can enter houses through cracks in the basement sub-slab or walls that are in contact with soil. Gaps at floor/wall joints or through porous concrete block. Open sump pits, openings around utility penetrations and floor drains. Emission from water (particularly ground or well water)
The World Health Organization estimates that 10% of all lung cancers are caused by radon exposure. Health Canada estimates that 14% of Canadian lung cancers are caused by radon exposure. Radon is considered to be the second leading cause of lung cancer, after smoking.
Radon levels and migration of Radon are unpredictable and vary greatly moving beneath the layers of soil by traveling to low pressure areas. This unpredictability is why Radon readings in neighboring homes can be totally different from each other. In the heating season Radon tends to migrate to lower pressure areas like your basements. Therefor the Radon levels are generally higher in the winter time because the windows are closed and the ground is usually frozen so the gases are not able to dissipate to the surface.
The Canadian guideline for radon in indoor air is 200 bq/m3. The Health Canada guidelines require that homes with levels over 600 bq/m3 are to be remediated within 12 months, while homes with levels between 200-600 need to be remediated within 24 months.
