Manufacturers of dose calibrators who gave calibration settings for various radionuclides sometimes do not specify the type of radionuclide container the calibration is for. The container, moreover, may not be of the same type as those a user might purchase. When these factors are not considered, the activity administered to the patient may be significantly different from that intended. An experiment is described in which calibration factors are determined for measurement of Xe-133 activity in vials in a dose calibrator. This was accomplished by transferring the Xe-133 from the commercial vials to standard NBS calibration ampuls. Based on ten such transfers, the resulting correction factor for the dose calibrator was 1.22.
剂量校准仪的制造商在给出各种放射性核素的校准设置时,有时并未指明该校准所针对的放射性核素容器类型。此外,该容器的类型可能与用户可能购买的容器不同。若不考虑这些因素,给予患者的活度可能与预期值有显著差异。本文描述了一项实验,其中确定了剂量校准仪测量小瓶中Xe - 133活度的校准因子。这是通过将Xe - 133从商用小瓶转移至标准的美国国家标准局校准安瓿来实现的。基于十次这样的转移,剂量校准仪最终的校正因子为1.22。
