Pioneering Research on Manufacturability of Radionuclides for Nuclear Medicine by Fast Neutrons

为了在日本利用强快中子生产核医学用放射性同位素（RI），我们对生产适用于核医学的放射性同位素（γ射线、β射线和正电子放射性核素）的核反应截面进行了评估。我们通过模拟一个现实的RI生产系统来计算生产的RI的放射性。我们考虑了所有RI的可制造性，包括新的候选人以及已经使用的RI。我们获得了20个放射性核素的放射性核素，其中18个放射性核素与靶元素不同，可以进行化学分离。

In order to produce radioisotopes (RIs) for nuclear medicine by using intense fast neutrons in Japan, we evaluated nuclear reaction cross sections for the production of RIs (gamma-ray, beta-ray and positron emission nuclides) which are suitable for nuclear medical care. We calculated the radioactivity of produced RIs by simulating a realistic RI-production system. We took account of the manufacturability of all RIs including new candidates as well as already used RIs. We obtained 20 RIs for gamma-ray emission nuclides, in which 18 RIs are different from target elements and can be chemically separated.
