Abstract

In k0-neutron activation analysis, HPGe detectors have to be calibrated up to about 3.1 MeV, in order to properly determine the Na, Ca and S content of analytes. Commercial radioactive sources cover the energy range only up to 2.2 MeV, but with activation in the reactor, additional high-energy gamma emitter radionuclides (72Ga, 56Mn, 116In and 24Na) can be produced. At a prompt-gamma activation analysis station, where the calibration is available up to 12 MeV, we derived accurate gamma-ray energies and relative intensities for these radionuclides and subsequently used them for broad energy-range efficiency and nonlinearity calibration of NAA detectors as well as a low-level counting station.
