Description
The selenium content of a variety of food items representing a normal hospital diet was determined by cyclic instrumental neutron activation analysis (CINAA) through the 162 keV gamma-ray of the 77mSe nuclide. The CINAA method is very simple and rapid. It involves irradiation of a sample for 20 s, decay for 20 s, and counting for 20 s. The precision of the method was significantly improved by recycling the samples up to 4 times. The accuracy was evaluated by analyzing a number of certified reference materials of varied selenium levels. (author) 18 refs.; 5 tables
