Abstract

Procédé et appareillage détecteur de radon. Cet appareillage comporte une enceinte protectrice 10 présentant une ouverture, cette enceinte étant enterrée dans le sol, avec son ouverture disposée en bas. Un corps 13 de matière détectrice de particules alpha est disposé à l'intérieur de cette enceinte de manière à être exposé aux gaz émanant du sol. Une certaine quantité de matière poreuse 14 ferme l'ouverture de l'enceinte. Application : prospection de l'uranium.
