摘　　要：目的采用改良分类法对放射性废物库进行分类管理并处置放射性废物;测定放射性废物库辐射波动情况研究其运行效果。方法通过以半衰期相同、相近的分类法对放射性废弃物进行分类,放射性废物采用货架式存放,放射性实验动物尸体采用醇性固定液浸泡防腐;放射性废弃物进、出库前、后对现场辐射水平进行监测。结果改良分类法处置放射性废物后放射性废物库总存量中的多数放射性废物能在较短时间内达到免管废物效果,放射性废弃物的总存量大幅减少到近37%水平。结论处置流程简洁、合理,值得在众多医疗、科研等中、低强度放射性应用单位推广试用。Objective To carry out the classification management of radioactive wastes by the modified classification method and measure the radiation and fluctuation of radioactive wastes and research their operational effects. Methods The radioactive wastes were classified by the same and similar classification method during half-life, the radioactive wastes were stored on shelves, the radioactive experimental animal carcass were soaked for anticorrosion by the alcohol stationary liquid,and the scenic radiation levels were monitored before and after entering and leaving the warehouse. Results Most radioactive wastes in the total stock after the radioactive wastes were disposed by the modified classification method could reach the effect of exempting waste in a short time, and the total stock of radioactive wastes greatly decreased to 37% or so. Conclusion The disposing course is easy and rational, which is worth promotion and application in the medium-level and lowlevel radioactive units such as medical and research units.
