Dependence of luoluminescence on rate of irradiated sodium chloride dissolution

The method of rotating disk has been used to investigate the effect of dissolving rate on lyoluminescence of γ-irradiated sodium chloride monocrystals in water and aqueous solutions of sodium chloride and thallium chloride. Irradiation and lyoluminescence measurement have been carried out at room temperature. It is shown that at the constant dissolving rate, the intensity of lyoluminescence is constant, while in the case of alterations of the angular rate of disk rotation the quantum lyoluminescence yield is in direct proportion to the dissolving rate of sodium chloride. Possibilities of using lyoluminescent measurements to determine the rate of solid substance dissolving, are discussed
