Abstract
This device has been achieved more especially in view of the control, by measure of activity {alpha}, of chemical separations. The sought-after features were the following: - simple handling; possibility to do some measures fast and frequent. It imposed the choice of an ionization chamber at air pressure; - possibility to count {alpha} in presence of a continuous {beta} background noise, which imposed a resolution time as short as possible; - absence of micro-phonics, which imposed a study of suspension of the room; - great safety of use. (author) [French] Cet appareil a ete realise plus particulierement en vue du controle, par mesure d'activite {alpha}, de separations chimiques. Les caracteristiques recherchees etaient les suivantes: - maniement simple; possibilite d'effectuer des mesures rapides et frequentes. Cela imposait le choix d'une chambre d'ionisation a air a pression atmospherique; - possibilite de compter des {alpha} en presence d'un fond continu de {beta}, ce qui imposait un temps de resolution aussi court que possible; - absence de microphonie, ce qui demandait une etude du mode de suspension de la chambre; - grande securite de fonctionnement.
