abstract = "The long-lived gamma-radionuclidic impurities in the columns of spent Mo-99/Tc-99m generators one year after the calibration date have been determined by v-spectrometry. Three radionuclidic impurities fission products (Ru-103, Ru-106 and Sb-125) were detected. Also in the majority of samples, three radioisotopes of tungsten (W-181, W-185 and W-188) were also present. The contents of the impurities were found to vary,greatly. According to the activity, energy and half-life, the main contribution to the residual activity in the spent generators is due to the presence of Sb-125.",
