Abstract

Procédé et appareillage détecteur de radon. L'appareillage comporte une enceinte protectrice 10 délimitant un volume fermé et présentant une ouverture, cette enceinte étant enterrée dans le sol 12 avec son ouverture disposée en bas, un corps 13 non protégé par des écrans en matière détectrice de particules alpha, et une membrane 14 non poreuse, sélectivement perméable, fermant ladite ouverture, de telle manière que les gaz dégagés du sol et entrant dans l'enceinte traversent toute l'épaisseur de la membrane et quittent celle-ci. Application : prospection d'uranium.
