Abstract
A systematic investigation was carried out on the merits and limitations of anticoincidence counting for short-lived radionuclides (t 1/2 < 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: 108Ag, 110Ag, 165mDy, 20F, 75mGe, 179mHf, 86mRb, 46mSc, 77mSe, and 177mYb. Precision and accuracy of measurements were good, and detection limits were of the order of µg kg−1.
