Abstract

La conversion en dose d’une exposition au radon fait l’objet de débats. L’UNSCEAR a défini un coefficient de conversion de la concentration en radon vers la dose efficace à partir de modèles dosimétriques et d’informations épidémiologiques. La CIPR recommande d’évaluer le risque lié au radon à partir des études épidémiologiques. Pour permettre la prise en compte d’une exposition combinée à d’autres sources de rayonnements ionisants, elle a adopté des conventions de conversion en dose efficace inférieures de 10 à 30 % au coefficient de l’UNSCEAR, sur la base du suivi épidémiologique des mineurs d’uranium. Ainsi, des niveaux de référence différents pour la concentration en radon peuvent être déduits d’un même niveau de dose efficace suivant que l’on applique l’un ou l’autre facteur de conversion. Cependant, il convient de rappeler que ces différences sont négligeables par rapport aux incertitudes associées aux études tant dosimétriques qu’épidémiologiques et que les niveaux de référence ne sont que des outils pour aider à réduire aussi bas que raisonnablement possible l’exposition au radon et le risque qui en résulte.
