Radon is a colourless, odourless gas that occurs naturally as a byproduct of trace uranium and thorium breaking down in rock and soil. Radon is the only radioactive gas that exists in normal conditions and long term exposure is highly toxic; long-term radon exposure is the second leading cause of lung cancer in Canada.
High concentrations of radon in homes were discovered accidentally in 1985, and radon has since been realized as a hazardous material under the Ontario Health and Safety Act (OHSA). Radon accumulates in buildings slowly from the soil and rock beneath the building’s foundation: typical entry points include cracks in solid foundations, construction joints, gaps in floors, service pipes, and contaminated water supplies. Radon moves upwards beginning with the lowest level of the building in contact with the ground. Buildings containing high concentrations of radon might not have an even dispersion of the gas throughout rooms and floors – it is entirely possible for individual rooms to have high or low concentrations without affecting the adjoining rooms.
Cambium’s qualified professionals can perform radon testing services for your home or business to help you meet OHSA requirements and due diligence. After performing initial radon test we will provide you with a laboratory report and an assessment of the results.
