Development of a gamma ray monitor using a CdZnTe semiconductor detector.


The aim of this study was to develop a new X ray and gamma ray monitor using the CdZnTe semiconductor detector, which has high sensitivity at room temperature. The pulse height spectra and the detection efficiencies of a 10 mm x 10 mm by 2 mm thick CdZnTe detector were measured in the energy range of 10 keV to 1.8 MeV by using monoenergetic X ray and gamma… (More)
