Abstract
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 temperature. In order to provide a more constant sensitivity, a self-regulating pressure control has been developed which will alter the pressure on the droplet-containing medium to compensate for changes in operating temperature. The pressure control 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 is designed to maintain a constant degree of superheat of the detector liquid in activated detectors.
