| Abstract: | odine and bromine in foods(grain, beans ,potato,meat,egg,aquatic product,milk,vegetables,fruit, sugar and water )are determined by epithermal neutron activation analysis on aminiatllre neutron source reactor.The selection of shielding material for thermal neutron and cor-rection for interferences are discussed.The detection limit of this method is calculated.Themethod has been tested on some reference materials and the results agreed with the recommendedvalues. |
