Summary

Compton suppression and gamma-gamma coincidence techniques have been in existence for many decades primarily used in nuclear structure studies. Although there were a couple of original papers on Compton suppression neutron activation analysis (NAA) it was not till the early 1990’s that this technique was employed in a more systematic approach. While gamma-gamma coincidence was more frequently used the method was also not fully exploited in routine NAA. Both these methods have unique capabilities that can greatly ameliorate the analysis of radionuclides from NAA either by reducing the background significantly and/or eliminating spectral interferences. A succinct comparison of these two methods will be made including their advantages and disadvantages and how a simultaneous integration of both methods can be very advantageous in the competitive world of trace element analysis.
