R | PNEUMATIC TUBE GAMMA RAY IW SAMPLE FROM REACTOR DETECTOR ZexoToMuLTIPLER GAMMA RAYS from an activated sample are measured by allow- ing them to fall on a scintillation detector, which emits photons of visible light whose intensity is directly proportio of the absorbed gamma ray. The detector is coupled to a photomul- Uiplier tube, which detects the light emissions and converts them concentration at levels down to as little as 10 times the lower limit of detection. Analyses with an accuracy...
