Radon is not just a European issue. It is world wide. Our friends from NB Lung in Canada have done a short informative presentation about radon in New Brunswick in Canada. The presentation is informative and of interest. Although it is aimed at particular issues in New Brunswick, Canada, it is worth a look for information purposes.
Where ever you are in the world, it is easy to test for radon in your home or work premises . In the UK, all you need to do is contact a contractor member of The Radon Council and they will be able to advise.
