| Abstract: | Measurement of lifetime along with measurement of intensity allow to determine both uranium and plutonium concentrations. If exciting light absorption is taken into account and temperature correction is introduced the intensity of uranyl limunescence extrapolated to zero time is a function of uranium and the ratior0/r-a function of plutonium concentration. Stadi of characteristics of uranyl luminescence was performed using a spectrometer interfased with a microcomputer. Luminescence was excited by nitrogen laser. |
