《GB/T 11682-2008低本底α和/或β测量仪》由TC30(全国核仪器仪表标准化技术委员会)归口,TC30SC1(全国核仪器仪表标准化技术委员会通用核仪器和辐射探测器分会)执行,主管部门为国家标准化管理委员会。
本标准代替GB/T 11682-1989《低本底α测量仪》。本标准规定了低本底α和/或β测量仪的技术要求、试验方法和检验规则。本标准适用于测量弱α、β放射性活度或表面发射率的仪器,也适用于多用途仪器中的测量弱α或β放射性的部分。本标准不适用于测量α或β能谱类型的仪器。本标准与GB/T 11682-1989相比作了如下修改:
―――标准名称修改为《低本底α和/或β测量仪》;
―――增加了测量低本底β的内容;
―――“规范性引用文件”中增加了引用的标准;
―――“术语和定义”中增加了“串道比”的内容;
―――增加α与β的相互干扰指标,即串道比指标;
―――增加了仪器电磁兼容的要求和试验方法;
―――增加了对仪器软件的通用要求;
―――删除了“表1 仪器分级”中本底稳定性的技术指标;
―――删除了“表2 改变影响量的项目和要求”中变化限值和本底计数率的技术要求。


This standard specifies the technical requirements, test methods and inspection rules for low background alpha and/or beta measuring instruments.
This standard is applicable to the instruments to measure weak alpha and/or beta activity or surface emission rate. It also applicable to the multi-use instrument when is used to measure weak alpha or beta activity.
This standard is not applicable to measure alpha or beta energy spectrum instruments.
