Abstract

In this paper, we report the fabrication and characterization of the personal surveymeter using home made Cd_0.8Zn_0.2Te detector for the field application. The detector structure is bulk type and an Au electrode is formed by an electroless deposition method. The properties of the Au film were analyzed by the AFM, RBS and Auger spectroscopy. The reliability test results showed that TO-5 packaged CdZnTe detector had good stability. When the detector bias voltage was higher, the detector response was more stable at low temperature. The personal surveymeter also showed good linear response for a gamma dose rate from 1 mRad/hr to 500 Rad/hr
