• Short-lived radionuclides
• Pseudo-cyclic neutron activation
• Anticoincidence gamma-ray spectrometry

A systematic investigation was carried out on the merits and limitations of anticoincidence counting for short-lived radionuclides (t (1/2) %26lt; 75 s) used in instrumental neutron activation analysis (INAA) and pseudo-cyclic INAA (PC-INAA) methods for single as well as simultaneous multielement determinations in botanical and nutritional reference materials. The list of radionuclides of interest included: Ag-108, Ag-110, Dy-165m, F-20, Ge-75m, Hf-179m, Rb-86m, Sc-46m, Se-77m, and Yb-177m. Precision and accuracy of measurements were good, and detection limits were of the order of A mu g kg(-1).
