We have been conducting a cooperative research on the safe treatment of radioactive wastes especially experimental animals and solid wastes. Among them, 'dry-distilllation of animal wastes' , 'dry-distilllation of solid wastes' , 'various problems in incineration of organic liquid wastes' , 'removal of radioisotopes from inorganic liquid wastes' . 'safe handling of radioisotopes in molecular biology' , 'decontamination of vials contaminated with radioactive materials' and 'some problems during storage of radioactive wastes' were the main projects.Some of the progresses are as follows :(1) Dry-distilllation of animal wastes containing ^3H,^<14>C,^<32>P,^<35>S,^<45>Ca, ^<51>Cr and ^<125>I produced a highly condensed residues that were stable during a long period of storage time. Recovery of the isotopes was almost quantitative in every case.(2) Dry-distilllation of paper wastes and plastic wastes was also successful to substantially reduce the waste volume.(3) Hardly combustible organic liquid wastes were treated by washing with water and chemical pretreatment followed by incineration. This demonstrated a better method for this type of wastes.(4) Washing decontamination of counting vials was examined with water, alkali and methanol, and the utilization of a washing machine was also tried to establish an effective decontamination procedure.(5) Inorganic liquid wastes were treated with active charcoal to remove contaminated radioisotopes effectively.(6) To prevent the radioactive dusts evolving from the radioactive wastes in storage, a variety of device including adsorption and sealing in a specially designed bag was examined and proved successful.

我们一直在放射性废物特别是实验动物和固体废物的安全处理方面进行合作研究。其中，“动物粪便干馏”、“固体废物干馏”、“有机液体废物焚烧中的各种问题”、“无机液体废物中放射性同位素的去除”。主要项目为“分子生物学中放射性同位素的安全处理”、“放射性物质污染的小瓶的净化”和“放射性废物储存过程中的一些问题”。部分进展如下：（1）含^3H、^<14>C、^<32>P、^<35>S、^<45>Ca的动物废物的干蒸馏， ^ 51 Cr和^ 125 I产生高度浓缩的残留物，其在长时间储存期间保持稳定。在每种情况下，同位素的回收率几乎都是定量的。（2）废纸和塑料废物的干蒸馏也成功地大大减少了废物量。（3）难燃的有机液体废物通过水洗和化学预处理然后焚烧进行处理。这为处理此类废物提供了一种更好的方法。(4)采用水、碱、甲醇对计数瓶进行清洗去污，并尝试利用洗衣机建立有效的去污程序。(5)采用活性炭处理无机液体废物，有效去除污染的放射性同位素。(6)防止放射性粉尘逸出。 针对储存中的废物，包括吸附和密封在专门设计的袋子中在内的多种装置经过检验并证明是成功的。
