<I>The residual activities present in spent</I> <SUP>99</SUP>Mo-<SUP>99m</SUP>Tc <I>generators and</I> <SUP>81</SUP>Rb-<SUP>81m</SUP>Kr <I>generators were determined from a view point of the disposal of radiopharmaceuticals.</I><BR><I>The results showed that seven kinds of residual nuclides such as</I> <SUP>95</SUP>Zr-<SUP>95</SUP>Nb, <SUP>103</SUP>Ru, <SUP>90</SUP>Sr, <I>etc. were found in</I> <SUP>99m</SUP>Tc <I>generators with maximum level of 740 Bq/3.7 GBq (0.02μCi/100 mCi) at one year after the reference date. In</I> <SUP>81m</SUP>Kr <I>generators one year old, six nuclides such as</I> <SUP>57</SUP>Co, <SUP>63</SUP>Rb, <SUP>84</SUP>Rb <I>and others remained and these activities were less than 3.7 kBq/370 MBq (0.1μCi/10 mCi) .</I><BR><I>On the basis of these data, the disposal of</I> <SUP>99m</SUP>Tc <I>generators and</I> <SUP>81m</SUP>Kr <I>generators is discussed.</I>
