摘要
日本战败后遗弃的化学武器不断造成伤人事件的发生。在这些事件中,因接触者无识别能力而造成重大损失,其中又以芥子气毒剂伤人事件最多和最为严重。芥子气毒剂弹由于埋藏时间较长,锈蚀、泄露比较严重,已经无法从外观上与普通炮弹进行识别,传统的化学试剂识别方法对人员容易造成伤害。研究了非接触性的外中子源诱发γ谱识别方法,模拟计算了外中子源对芥子气毒剂弹照射后的γ谱。根据γ谱上Cl、S和Fe等关键核素的特征射线,便可完成对毒剂弹的识别。
After Japan was defeated, the chemical weapon that left in China injured people constantly. It made very grave lost to the Chinese because of people＇s innocent to it. In these accidents, mustard gas bomb is the most. It is more difficult to distinguish mustard gas bomb from other normal bomb in out because it embedded in the earth for long time; leakage , eroding and rust appearance looked very serious. So the untouched measure method, neutron source induce γ spectrum, showed very important. The Monte Carlo method was used in this paper to compute the γ spectrum when using neutron source irradiate mustard gas bomb. The characteristic radial of Cl, S, Fe and the other elements can picked up dearly. The result play some referenced role in analyzing γ spectrum.
