RADIATION DETECTOR

摘要

The present invention provides a radiation detection system for detecting X-ray and gamma rays featuring Cd 1-x Mg x Te in solid solution as a crystal semiconductor and electrical connection means. The crystal has a composition in the range of Cdo.99Mgo.01Te to Cdo.71Mgo.29Te and may be doped with indium or another Group III element, which may be suitable for use at room temperature as well as controlled temperatures. The present invention further provides a method for detecting X- or gamma ray radiation by (a) providing a solid solution Cdi-xMgxTe crystal in the composition range of Cdo.99Mgo.01Te to Cdo.71Mgo.29Te; (b) providing an electrical contact means for connecting the Cdi-xMgxTe crystal to an amplification, measurement, identification or imaging means; and (c) detecting the presence of the X- or gamma ray radiation.
