Abstract
The off-line γ-counting of in-beam activated radionuclides has been explored to extend the detection capabilities of prompt gamma activation analysis (PGAA). Such combination of the prompt measurement with a subsequent decay-counting is feasible if radionuclides with half-lives of minutes or hours are produced in the sample during neutron irradiation. Thanks to the simpler spectrum and the higher counting efficiency of decay counting, both selectivity and sensitivity can be improved. The pros and cons of the proposed method have been demonstrated on a series of industry-related measurements.
