ارزيابي خلوص راديونو كليدي ساماريم-153 توليد شده از طريق پرتودهي نوتروني ساماريم طبيعي در رآكتور تحقيقاتي تهران

Assessment of Radionuclidic Purity of Sm-153 Produced by Irradiation of Natural Samarium in Tehran Research Reactor (TRR)

Samarium-153 is one of the most widely used radionuclides in preparation of pain palliation radiopharmaceuticals of bone metastases. Therefore, it is important to realize the types and amount of impurities in the products. The aim of this study is to evaluate the produced impurities (154Eu, 155Eu & 156Eu) both theoretically and experimentally. These impurities are produced in 153Sm preparation by irradiation of natural samarium. In the experiment, the gamma spectra are recorded at different time durations, as the half-lives of impurities are longer than 153Sm half-life. Moreover, a comparison is also given to show that the results of the experiment and that of theory are in good agreement with each other, where it gives an accurate assessment of the amount and the type of impurities
