- This International Standard applies to portable instruments used for measuring the specific activity of beta-emitting radionuclides in food/foodstuffs and intended for operation under field conditions. This does not apply to low background laboratory instrumentation requiring highly skilled personnel. The instruments designed for measurement of beta contamination in foodstuffs under field conditions should not require special sample preparation other than machining (cutting, grinding, etc.). These instruments may be used in principle to measure beta emitting surface contamination and other radiation measurements as well, but these applications lie outside the scope of this standard. The same instruments intended for measuring foodstuffs can also be used for the measurement of environmental samples, such as soil, sewage, plant and animal life, etc. These instruments can be used to determine specific beta activity for a wide variety of samples under this standard. The purpose of this standard is to specify the main performance characteristics of instruments intended for measurement of specific activity of beta-emitting radionuclides in foodstuffs, their methods of testing and documentation requirements.

一文了解放射性药物基本知识
放射性核素纯度：指特定放射性核素的活度占总活度的百分数。对放射性药品中的放射性核素杂质进行测定。可用γ能谱仪检测。3. 放射性活度的测定：测量仪器为活度计、井型闪烁计数器和液体闪烁计数器。活度计可测量十几种至上百种放射性核素的活度，需用相应标准源标定。4. 放射性浓度：样品活度除以样品体积得到。常用单位为MBq/mL或mCi/mL。5. 比活度：单位质量放射性物质的浓度。...
《辐射事故应急监测技术规范》国家环境保护标准发布
现场监测时，仪器设备应能快速鉴定、鉴别放射性污染物，并能给出定性、半定量或定量的监测结果，量程适用，直接读数，使用方便，易于携带，对样品的前处理要求低。同时，应根据辐射事故应急监测预案，配置常用的现场应急监测仪器设备，主要包括α/β表面污染仪、x/γ辐射剂量率仪、便携式γ谱仪、中子辐射剂量率仪等现场监测仪器设备。 凡具备现场测定条件的监测项目，应尽量进行现场测定。...
