摘要

测量177Lu活性的准确性对于校准临床应用中使用的仪器至关重要。为了支持177Lu溶液的测量，现有的TDCR-Čerenkov方法已经扩展到该核素。在扩展方法中考虑了177Lu的β和γ跃迁的贡献。最后，用该方法得到的不确定度为0.62%，与液体闪烁计数的结果吻合较好。

Activity determination of 177Lu using TDCR-Čerenkov method

The accuracy of measuring the activity of ¹⁷⁷Lu is crucial for calibrating the instruments employed in clinical applications. To support the measurements of ¹⁷⁷Lu solution, the existing TDCR-Čerenkov method has been extended for this nuclide. The contribution of β and γ transitions from ¹⁷⁷Lu was taken into account in the extended method. Finally, the results obtained using this method, with an uncertainty of 0.62%, were found to be in good agreement with that derived from liquid scintillation counting.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
