Description

This article outlines a method for the absolute measurement of weak currents produced in an ionisation chamber. The measuring assembly consists basically of cavity ionisation chambers connected to an electro-metric device. When used to measure exposure dose rates, this apparatus can cover a range from 10 milli-roentgens/hour to 15000 roentgens/hour. (author)

Abstract (French)

Dans cet article, nous etudions une methode de mesure absolue de courants faibles issus de chambre d'ionisation. Nous decrivons un ensemble de mesure constitue essentiellement de chambres d'ionisation a cavite associees a un dispositif electronique. En appliquant ce dispositif a la mesure des debits d'exposition, on peut couvrir un domaine de 10 milli-roentgens/ heure a 15000 roentgens/heure. (auteur)
