Neutron Activation and Related Methods


A straightforward method for demonstrating the powerful back-ground reduction of Compton suppression spectrometers for neutron activation purposes is presented. The shorter acquisition time needed in Anti-Compton mode (A/C on) for peaks of appropriate counting statistics, compared to normal gamma counting (A/C off), allows a much higher sample throughput, thus compensating for the higher cost of the instrument. Two examples of artificial mixtures of radionuclides demonstrate the drastic time saving for measurement of monoenergetic decaying isotopes. The comparison of results from three different instruments proves the general usefulness of Compton suppression spectrometers for Neutron Activation Analysis of biological samples.
