Evaporation equipment for the rational measurement of the radioactivity of water; Dispositif d'evaporation pour la mesure rationnelle de la radioactivite de l'eau

Abstract

An apparatus is described whereby the water can be evaporated directly in the radioactive sample holder in which the sample is counted. Rapid evaporation is obtained by the heating of the dish combined with the application of a jet of hot air. Liquid is added to the dish and the heating stopped automatically at the end of evaporation. The speed of evaporation and the Losses in activity as a function of the degree of heating were studied for various substances and different qualities of water (permuted water, tap water, rainwater). Complexones are added to avoid losses of activity. (author) [French] Un ensemble d'appareils permet d'evaporer l'eau directement dans la coupelle de mesure. Le chauffage de la coupelle combine avec l'application d'un jet d'air chaud assure une evaporation rapide. L'alimentation de la coupelle et l'arret du chauffage a la fin de l'evaporation sont automatiques. La vitesse d'evaporation et les pertes d'activite en fonction de l'intensite de chauffage ont ete etudiees pour differents corps et differentes qualites d'eau (eau permutee, eau de ville, eau de pluie). On ajoute des complexons pour eviter des pertes d'activites. (auteur)
