| Abstract: | During nuclear decommissioning, an investigation of location and radioactivity activity at ＂hotspot＂ at the decommissioning site plays an important role. A CdZnTe gamma spectrometer system combined with lead collimator is built in this work, aimed to be an assistant measurement tool for Gamma Camera. Gamma Spec- trum analysis software named MiniAnalysis is developedy Visual C #, which is an efficient tool in in-field measurement. According to the preliminary test by using the 137 Cs gamma source, the hemisphere CdZnTe gamma spectrometer could be used in the measurement of the activity of ＂hotspot＂. |
