| 摘 要： | 气溶胶泄漏问题是各种放射性实验过程和放射性物质储存、运输过程中普遍存在的问题 ,膨润土和砂则是常用的高放处置回填材料。工作中建立了层剖取样、微波浸提、ICP AES分析的气溶胶泄漏研究方法 ,来评估膨润土和砂对气溶胶的封堵性能。结果表明 :膨润土层的透过率远小于砂层。此外 ,对膨润土和砂 ,透过率与其气体渗透系数有一定的正相关性。

| Abstract: | Aerosol leakage often occurs in many cases such as radioactive tests and package and shipment of radioactive materials. In this paper bentonites and sands widely used for radioactive wastes disposal are evaluated in terms of their properties of aerosol barrier on the basis of different established methods. It is concluded that aerosol barrier property of bentonites are far better than that of sands. |
