Best Choice of High Purity Germanium (HPGe) Detector
The choice of the best HPGe detector for your particular measurement situation is based on a few simple rules. The rules are given and are based on some basic concepts about how the detection process works, how gamma rays penetrate materials, and the principles of gamma-ray spectroscopy.
