标准摘要
[中文适用范围]： IEC 61948 的这一部分涵盖了核医学中使用的放射性核素校准器的常规测试。此类装置利用井型电离室和以活动为单位的直接读数。 IEC 61303 中描述了确定性能参数的要求和具体方法。这些方法主要设计用于验收测试 [外文原描述]： 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.
