摘要

对２００ＭｅＶ高能电子束在钨靶中作用的物理过程进行Ｍｏｎｔｅ—Ｃａｒｌｏ模拟，确定电子－光子转换靶（Ｗ）的最佳厚度为７—９ｍｍ。并给出

Ｘｅ高压气靶为３ＭＰａ，当照射３ｈ，在最佳回收时间５．２６ｈ回收氙气，可获得１２３Ｉ的活度约５．９２ＭＢｑ。

Abstract

The physical process of 200MeV electron beam bombarded on Tungsten was simulated by Monte Carlo method. The optimum thickness of the electron-photon transfermation target is estimated to be 7- 9mm. It is shown that an 123I yield of 5.92MBq can be obtained or optimum retrieving time of 5.26h

with a 3MPa 124Xe gas target and 3h borobardment time.
