In order to improve the reliability of safety assessment of radioactive waste disposal, femto-second laser induced fluorescence spectroscopy system has been developed for the case of Eu-salicylic acid complexes. From the Stern-Volmer plot based on fluorescent intensity and its life-time, static quenching was found to be dominant under the experimental conditions. The stability constants of Eu-salicylic acid was evaluated.
