<I>It is well known that very large storage tanks for radioactive liquids are necessary for the disposal of liquid radioactive waste.</I><BR><I>In vitro tests in radioimmunoassay in nuclear medicine are rapidly increasing for clinical examination causing marked increase in the volume of liquid radioactive waste. Thus we have developed a system for decontaminating radioactivity from liquid waste.</I><BR><I>In the first step, the liquid waste is boiled by a sterilizer and, in the second step, this sterilised liquid is filtered by a cylindrical filter (Toyo filter No.84) . After filtration, the liquid waste is passed into a beaded charcoal column and an ion exchange resin (Amberlite IRA 402) column. After these treatments, the radioactivity level of liquid waste is lowered to less than 1 % of the original radioactivity.</I><BR><I>We are now in the planning stages of building an apparatus for practical use.</I>
