IEC 61563:2019适用于用于测量食品和/或食品中γ发射放射性核素的活度和/或活度浓度的仪器。本文件适用于现场条件和测量设施中使用的总计数型仪器和脉冲高度分析型仪器。本文件不适用于使用锗探测器的高分辨率光谱仪。本文件适用的仪器可用于测量各种样品（如土壤、污水、植物和动物）的γ发射放射性核素的活度和活度浓度。本文件的目的是建立性能要求，提供测试方法，并规定一般特性、一般测试条件以及用于确定仪器是否符合本文件要求的放射性、环境、机械和电磁特性。测试结果为最终用户和制造商提供了关于仪器可靠测量γ发射放射性核素的活度和/或活度浓度的能力的信息。这第二版取消并取代了2001年出版的第一版。与上一版相比，此版本包括以下重大技术变更:a)先前版本适用于手持式和便携式仪器。本版适用于可运输型和安装型仪器，以及前版的范围。手持式和便携式仪器主要用于事故后情况，然而，便携式和安装式仪器可以在恢复阶段使用。b)根据GUM引入测量不确定度。c)引入ISO 11929中定义的检测限，以规定最小可检测活性。d)环境要求、机械要求和电磁要求根据IEC 62706进行更新。e)介绍了测量报告的样本格式

IEC 61563:2019 applies to instruments used to measure the activity and/or activity concentration of gamma-emitting radionuclides in food and/or foodstuffs. This document applies to instruments used both as gross count type instruments and pulse height analysing type instruments used in field conditions and in measurement facilities. This document does not apply to high-resolution spectrometers that use germanium detectors.
The instruments to which this document applies can be used to measure the activity and activity concentration of gamma-emitting radionuclides for a wide variety of samples, such as soil, sewage, plant, and animal life.
The object of this document is to establish performance requirements, to provide test methods and to specify general characteristics, general test conditions, and radiological, environmental, mechanical and electromagnetic characteristics to be used to determine whether an instrument meets the requirements of this document. The test results provide information to end-users and manufacturers regarding the capability of instrument for reliable measurement of the activity and/or activity concentration of gamma-emitting radionuclides.
This second edition cancels and replaces the first edition published in 2001. This edition includes the following significant technical changes with respect to the previous edition:
a) The previous edition applied to handheld-type and portable-type instruments. This edition applies to transportable-type and installed-type instruments, as well as the scope of the previous edition. The handheld-type and portable-type instruments are mainly used in case of a post accidental situation, however, the transportable-type and installed-type instruments can be used through recovery phase.
b) Uncertainty of measurement according to GUM is introduced.
c) Detection limit defined in ISO 11929 is introduced to specify a minimum detectable activity.
d) Environmental requirements, mechanical requirements and electromagnetic requirements are updated according to IEC 62706.
e) Sample format of measuring report is introduced
