However, it is critical for these HPGe spectrometry system to be robustly calibrated for energy, detection efficiency and peak-shape. Calibration of the spectrometer generally requires mixed gamma standards that contain as many as eleven radionuclides. Unfortunately, some of these radionuclides are short-lived with relatively short half-lives e.g. 27.7 and 64.8 days for Cr-51 and Sr-85, respectively. The short-lived nuclides limit the effectiveness of such calibration standards to only a few months. In this work, we report the development of a tri-nuclide calibration standard containing relatively long-lived Eu-154, Eu-155 and Sb-125 that allows it to remain effective for at least two years. The key to using the tri-nuclide as a calibration standard for HPGe spectrometry is to remove interferences resulting from coincidence summations.</p></div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 8","pages":"5329 - 5333"},"PeriodicalIF":1.6,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
