Abstract: |
|
A comprehensive study on a laboratory-based Gamma Spectrometry has been presented in this paper for food and environmental samples. The system comprises of HPGe detector with proper cooling for minimizing thermal generation of charge-carriers and appropriate shielding to reduce background emission; associated processing electronics and acquisition as well as analysis software. The choice of HPGe detector for laboratory-based Gamma Spectrometry, its radiation interaction mechanism and system optimization have been presented. |
