X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy—Part 1:Radiation characteristics and production methods


Standard in brief
Scope of Application:  
本文件描述了用于根据运行实用量校准防护水平剂量仪和剂量率仪X和γ参考辐射的辐射特性和产生方法。
本文件适用于空气比释动能率不小于1 μGy·h-1的参考辐射场。
本文件不适用于需要对(天然)本底辐射进行特殊考虑,低于此下限的空气比释动能率。
第4章~第6章规定的辐射质,有充分的公开信息来规定匹配或表征参考场,以实现对于与体模相关运行实用量约为6%~10%扩展不确定度(k=2)的目标。附录A~附录C中描述的X射线辐射场未被指定为参考X辐射场。
