Radon: Technical information

In Canada, a number of resources are available which provide technical guidance on taking action on radon. Radon in Canada has been studied through surveys of homes and other buildings across the country. In addition to this, radon mitigation techniques and their effectiveness have also been studied. The links below provide useful guidance and select research papers on radon in Canada.
