<I>A simple and rapid method for activation analysis of uranium in human teeth was proposed. The nuclear reaction of</I> <SUP>235</SUP>U (<I>n, f</I>) <SUP>140</SUP>Ba <I>was used and the activity of</I> <SUP>140</SUP>La <I>in equilibrium with</I> <SUP>140</SUP>Ba <I>was measured. The barium fraction was separated in the form of barium chloride from the hydrochloric acid solution of the irradiated teeth sample, and then purified by the use of cation exchange resins. The radiochemical purity of the final lanthanum fraction was high enough. Several teeth samples were analysed, giving the uranium contents of 24-44 ppb</I>.
