Description
A simplified method of urinary uranium analysis using sodium fluoride pellet has been developed. In this method a predetermined volume of urine not previously subjected to any chemical treatment is dropped on a pellet of sodium fluoride (NaF) powder, and after drying, it is sintered in an electric furnace for about 10 min at a temperature of 950℃. When the sintered pellet is exposed to ultra violet light, it emits fluorescence of a certain wavelength characteristic of uranium, and of intensity fairly well proportionate in a wide range with the concentration of uranium in the sample urine. An important merit of this method lies in its simplicity, and it can be effectively used in practice for quantitative analysis of urinary uranium in radiation protection measures. (author)
