6、⋯⋯，.·....·..·..·.·..............................⋯⋯GB/T12128.2-1999前言本标准等效采用国际标准ISO8769-2;1996《用于校准表面污染监测仪的参考源第二部分:能量低于。.15MeV的电子和能量低于1.5MeV的光子》。国标GB/T12128-1989已经对p谱最大能量Em->0.15MeV的俘发射体参考源作出了规定和推荐，但尚无能量低于。.15MeV的电子(或俘粒子)和能量低于1.5MeV光子的参考源标准。本标准对除sH以外的出射能

7、量低于0.15MeV的电子(或俘粒子)和能量低于1.5MeV的光子的参考辐射作出了规定。ISO8769-1对'H参考辐射源作了专门的规定。Y和低能p表面污染的监测和监测仪表的校准存在着不可忽视的困难问题，本标准的制定有助于解决这一问题。本标准在等效采用ISO8769-2时，下列章节略有改变:—1，简化了原标准中第一章的内容;—2，删去原标准中的第二章的内容，改为2"引用标准”;—3，对溯源性和均匀性的定义作了适当修改;—4，在不改变原意的情况下，对该章叙述方式略加修改;-5.2.1.1，将第二段和第三

8、段互换;本标准的附录A、附录B都是提示的附录。本标准由中国核工业集团公司提出。本标准由中国核能标准化技术委员会归口。本标准起草单位:中国辐射防护研究院第一研究所。本标准主要起草人张延生、杨俊武、陈慧莉。CB/T12128.2-1999ISO前言ISO(国际标准化组织)是由各国标准化团体(ISO成员团体)组成的世界性的联合会。制定国际标准的工作通常由ISO的技术委员会完成各成员团体若对某技术委员会确立的项目感兴趣，均有权参加该委员会的工作。与ISO保持联系
