CONSTANT SENSITIVITY SUPERHEATED DROPLET RADIATION DETECTOR/DOSIMETER

摘要

TITLE Constant Sensitivity Superheated Droplet Radiation Detector/Dosimeter INVENTORS Hugh Boniface Robert Noulty John Jevcak Harry Ing Radiation detectors and dosimeters having superheated droplets of detector liquid as the radiationsensitive component have been found to have significant variation in sensitivity with changes in operating temperature. In order to provide a more constant sensitivity, a self-regulating pressure control means has been developed which will alter the pressure on the droplet-containing medium to compensate for changes in operating temperature. The pressure control means is for instance a mechanical system selected from a pressure-multiplying piston or bellows assembly pressurized by a volatile liquid, and a spring-loaded elastic diaphragm assembly. This pressure control means is designed to maintain a constant degree of superheat of the detector liquid in activated detectors.
