摘要

介绍了固体径迹和火花计数器技术在热粒子定位中的应用。测定了 6种滤膜的最大流量、流阻及流量变化

并在某工号进行了模拟热粒子取样。火花放电图像可以大面积、清晰地展现出热粒子在滤膜上的位置。利用固体径迹技术对放射源均匀性进行了检验

结果表明

采用推荐流程制备的钚（α）标准源

其均匀性比前苏联制备的同类标准源优越（前者U在 10 %— 18%

而后者在 33%— 4 7% ）。

Abstract

The applications of the SSNTD methods for determination of hot particle location in filter and uniformity of radioactive sources were described. With the introduction of SSNTD and spark counter in the application of hot particle location

the general properties of six kinds of filter including the flow rate and flow resistance were measured and analyzed. By hot particle simulating sampling

the results of the hot particle location in filter and uniformity of U and Pu radioactive sources were given. The result shows

uniformity of U and Pu sources made by our procedure is better than that by ex-Soviet.
