Radon testing guides

Le radon est un gaz radioactif qui se forme dans le sol quand l’uranium se dégrade. Il entre par les fissures de la fondation et les joints des tuyaux. L’isolation et une maison étanche le retiennent à l’intérieur. Des années d’exposition causent le cancer du poumon, et ce gaz reste méconnu. Utilisez la recherche pour les mots que les gens cherchent : gaz radioactif, uranium, fondation, maison étanche, cancer du poumon, becquerels.

Run the HRV as you normally do, then test. Do not assume the ventilator has already solved radon.
