WebPhoton activation analysis (PAA) has been used for various multi-elemental analyses on biological, archaeological and environmental samples for decades. The PAA procedure usually includes: irradiation, measurement, peak reading and PAA analysis. Irradiation is normally performed by the high energy bremsstrahlung photon beam created by the ... 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.
