Radon in the Home

Radon is a colourless, odourless gas that is released from the degradation of uranium naturally present in rock and soil. Radon levels outdoors are generally low; however, radon can enter buildings and homes through cracks and openings in the foundation and levels can become much higher indoors, especially in basements and lower floors. Long term exposure to radon increases the risk of lung...

Effective Interventions to Reduce Indoor Radon Levels

Radon represents one of the environmental exposures that can be reduced with effective and practical solutions, reducing an individual’s risk of developing lung cancer. There is extensive literature supporting the cost-effectiveness of radon abatement compared with other healthcare and environmental interventions. Of the remediation measures evaluated to reduce indoor radon levels in already...

Residential Indoor Radon Testing

Radon is a known carcinogen, and is estimated to cause up to 10% of all lung cancers in Canada. It is a radioactive gas that is produced by the decay of uranium. Radon is naturally occurring, and emanates from soil and rocks. It percolates up through soil into buildings, and if it is not evacuated there can be much higher exposure levels indoors than outdoors. Fortunately, high radon levels can...
