DEVICE FOR RECORDING GAMMA TOPOGRAMS,
Abstract
A device is proposed for recording gamma topograms which contains a scintillation pickup, a linear amplifier, a single-channel amplitude analyzer, a counting-speed meter, a system of control of the scintillation pickup, and a recording device, the distinguishing feature of which is that for the purpose of increasing the clearness of the 'scentigrams' and reducing the overall time of scanning by automatic regulation of the scanning step, in the apparatus there is included a relay-threshold electrical scheme which converts electrical pulses coming from a counting-rate meter into command signals to a system which decreases the scanning step in the passing of the scintillation pickup over the area with increased accumulation of radioactivity.
