This standard specifies the method for determining the Cs radioactivity concentration in medium-level radioactive waste liquid (hereinafter referred to as medium-level radioactive waste liquid) and its slurry by Y counting method, including the reagents and instruments used, measurement, result calculation and precision requirements. This standard is applicable to the determination of Cs radioactive activity concentration in intermediate-level radioactive waste liquid and its slurry produced by spent fuel reprocessing and stored for a long time (more than 12 years). The detection limit of the method is 1.9×10Bq/L.
