摘要
为评估基于激光、X或γ射线的无损检测系统检测放射性材料的安全性,基于光子-物质作用形式各反应截面数据库探讨单个放射性材料原子对激光、X或γ射线的作用(反应)几率,得出常用激光检测、X或γ射线探测放射性材料时放射性材料是安全的结论,并根据材料安全性推断激光、X或γ射线照射到放射性材料表面强度的安全阈值量级。
In order to assess the security of laser, X-ray or γ-ray-based testing of radioactive materials, the reaction probability of a single radioactive atom to the photons with specific frequency was discussed by having the cross-section database of various reaction of the photo to atoms based. Testing security was confirmed and the threshold values of laser, X-ray or γ-ray exposed on radioactive materials were derived.
