标准范围

IEC TR 61948-4:20 19作为IEC TR 61948-4:20 19 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC TR 61948-4:20 19涵盖核医学中使用的放射性核素校准器的常规测试。这种装置利用阱型的电离室和以活性为单位的直接读出。IEC 61303中描述了确定性能参数的要求和具体方法。这些方法主要用于验收测试。IEC TR 61948-4:20 19取消并取代了2006年发布的第一版。本版构成技术修订版。与上一版相比，本版包括以下重大技术变化:更新了测定系统线性的测试方法，以反映放射性核素校准品的技术发展。

IEC TR 61948-4:2019 is available as IEC TR 61948-4:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC TR 61948-4:2019 covers the routine testing of radionuclide calibrators used in nuclear medicine. Such devices utilise ionisation chambers of the well type and a direct readout in units of activity. Requirements and specific methods to determine performance parameters are described in IEC 61303. These methods are primarily designed for acceptance testing. IEC TR 61948-4:2019 cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: the test method to determine system linearity has been updated to reflect the technical developments of radionuclide calibrators.
