Low level gamma spectrometry

Description

The low activity domain considered is below 0.01 Bq/cubic cm or Bq/g. Methods developed at the CEA to reduce background noise are examined, in particular protection against cosmic radiations, natural and artificial radionuclides. The low activity laboratory is described (buildings, ventilation, measurement chamber, shielding, very low activity lead, detector) and main results obtained are given

Abstract (French)

Le domaine considere se situe au-dessous de 0,01 Bq/cm3 ou Bq/g. On etudie les methodes developpees au CEA pour reduire le bruit de fond, en particulier protection contre le rayonnement cosmique et les radionucleides naturels et artificiels. On presente le laboratoire de faible activite (implantation, ventilation, chambre de mesure, blindages, plomb tres faible activite, detecteur) et on donne les principaux resultats obtenus
