Improvement of the capabilities of PGAA by coincidence techniques

Applicability of the γ–γ regional coincidence method to prompt gamma activation analysis has been examined in a series of model experiments. It is shown that the requirement of coincidence with a spectral range instead of a single peak greatly improves the signal to background ratio, yet preserves the linear relationship between concentration and analytical signal. The method is especially suitable for trace analysis of solutions containing hydrogen, and of matrices containing boron or other strong single γ-ray emitters.
