TITLE Constant Sensitivity Superheated Droplet Radiation Detector/Dosimeter INVENTORS Hugh Boniface Robert Noulty John Jevcak Harry Ing ABSTRACT OF THE DISCLOSURE Radiation detectors and dosimeters having superheated droplets of detector liquid as the radiation- sensitive component have been found to have significant variation in sensitivity with changes in operating temper- ature. 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.
