Abstract

At Dalat nuclear research reactor, the gamma - gamma coincidence method is eficiently used in data nuclear research direction. By this method, some laboratories in the world test neutron activation analysis of geological, biological and environmental samples. In this paper, we present the determination of the selenium content in biological sample by gamma – gamma coincidence method. The results showed that the compton scattering was suppressed. The ratio of peak counts/back was improved up to 64.2 times. The detection limit for selenium in biological sample was enhanced to 8.9 times to compare to the method one detector system.
