Description

Gaseous permeation is a complex phenomenon of gas transfer through some polymers. Original in respect of conventional studies where permeation occurs between two gaseous phases, the present study concerns radon 222 transfer between water and air through a membrane. Polypropylene membranes are tested with an experimental device following time evolution of the phenomenon by measurement of volume activity in water and in air. An application of this study to a method for determination of radon concentration in water by measurement of concentration in air is discussed

Abstract (French)

Le terme permeation gazeuse decrit un phenomene complexe de transfert de gaz a travers certains polymeres. Originale par rapport aux etudes traditionnelles ou la permeation s'effectue entre deux phases gazeuses, la presente etude concerne le transfert du radon-222 entre de l'eau et de l'air via une membrane. Un dispositif experimental a permis de tester des membranes en polypropylene, en suivant l'evolution temporelle du phenomene par la mesure de l'activite volumique du radon-222 dans l'eau et dans l'air. Une application de cette etude comme methode pour determiner la concentration du radon dans l'eau en mesurant celle de l'air est discutee
