近些年,随着癌症患者的不断增多,使用医用放射性同位素进行诊断和治疗的人越来越多,放射性治疗成为治疗癌症的主要手段之一,其每年的产值可达到数百亿美元。~(186)Re~g是一个性质十分理想的核素,其半衰期为3.78d,β射线的最大能量为1.07 MeV,伴随γ射线的能量为0.137 MeV(9.47%)。~(186)Re~g标记的二磷酸盐可用于骨骼显像,也可用于骨转移癌和疼痛性前列腺癌。商业上,生产~(186)Re~g是使用反应堆发射的中子通过辐射俘获反应来生产的,但 In recent years, with the increasing number of cancer patients, more and more people use medical radioisotopes for diagnosis and treatment. Radiation therapy is one of the major treatments for cancer and its annual output value can reach tens of billions of US dollars. ~ (186) Re ~ g is a very ideal nuclide with a half-life of 3.78d, a maximum beta energy of 1.07 MeV and an accompanying gamma energy of 0.137 MeV (9.47%). ~ (186) Re ~ g labeled diphosphate can be used for bone imaging, but also for bone metastases and painful prostate cancer. Commercially, the production of ~ (186) Re ~ g is produced using a radiation-capture reaction using the neutron emitted by the reactor but
