地下核爆炸中竖井空腔半径小，受围岩介质的影响，核爆中子对核材料的燃耗有一定影响，继而影响放射化学诊断分析。本文采用M onte Carlo程序模拟了装置自身燃耗与竖井环境下中子反照引起的核材料燃耗之间的关系，给出了特殊环境下反照效应对不同反应道燃耗的影响和分析方法。俘获反应道受反照影响大，放射化学诊断方法中用到核素的俘获反应道时需考虑反照的影响后才能对装置本身开展正确的分析。

T he neutron field distribution is affected by the surrounding medium in the underground nuclear explosion .It will influence the radiation chemical diagnosis .By Monte Carlo simulation , the fuel burnup induced by device and neutron albedo was calculated .T he analysis method of albedo effect on radiation chemical diagnosis result under special environment was proposed .Neutron albedo should be considered when capture reaction burnup fraction is used ,and then correct analysis can be carried out on the nuclear device .
