WebMar 8, 2016 · Photon activation analysis (PAA) is an established non-destructive analytical technique . The sample is irradiated with a photon beam of energy higher than the threshold of photonuclear reactions. After the end of the irradiation, the sample is counted in a germanium based gamma spectrometry system. There are a number of detector types and configurations used in NAA. Most are designed to detect the emitted gamma radiation. The most common types of gamma detectors encountered in NAA are the gas ionisation type, scintillation type and the semiconductor type. Of these the scintillation and semiconductor type are the most widely employed. There are two detector configurations utilised, they are the planar detector, used for PGNAA and the well detector, used …
