CdTe detectors in nuclear radiation dosimetry

Research in dosimetry systems at Radiation Monitoring Devices has resulted in the development of a technique which permits the energy deposited in the CdTe detector to be directly related to the tissue dose over a wide range of energy. This relationship has been utilized in the development of two prototype dosimeter instruments. The first of these serves as the basis for a compact unit which provides nearly tissue equivalent response to personnel exposure to potentially large and uncharacterized doses of radiation. The second instrument is a solid state integrating dosimeter system, developed for space flight applications, which is designed to monitor crew exposure to gamma rays and particles. Several CdTe detectors were used with filtering and anticoincidence techniques to separately monitor exposure to gamma rays and charged particles. (orig.)
