Results from tests of radiation detection instruments with radionuclide identification capabilities will depend on the sources used for the tests. Radionuclide identification detectors are designed to measure photons and provide an identification of the source being measured. High-resolution spectra need to be acquired to determine all the observable peaks in the source spectra before testing these types of instruments. These peaks may be due to impurities and/or scatter peaks in the sources. This paper discusses the issues encountered with the response of a radioisotope identification device due to scatter peaks in one type of source used for testing. In addition, it provides spectra for different source types and source constructions to compare the differences in scatter, allowing for a better source type selection for instrument testing.
具有放射性核素识别能力的辐射探测仪器的测试结果将取决于测试所使用的源。放射性核素识别探测器旨在测量光子并识别被测量的源。在测试这类仪器之前，需要获取高分辨率光谱以确定源光谱中所有可观测到的峰。这些峰可能是由于源中的杂质和/或散射峰。本文讨论了在一种用于测试的源中，由于散射峰而导致放射性同位素识别装置响应方面遇到的问题。此外，它还提供了不同源类型和源结构的光谱，以比较散射差异，从而为仪器测试更好地选择源类型。
