There is a growing need for the production of radioisotopes for both diagnostic and therapeutic medical applications. Radioisotopes that are produced using the (n,γ) or (γ,n) reactions, however, typically result in samples with low specific activity (radioactivity∕gram) due to the high abundance of target material of the same element. One method to effectively remove the isotopic impurity is electro-magnetic mass separation. An Ion Source Test Facility has been constructed at TRIUMF to develop high-intensity, high-efficiency, reliable ion sources for purification of radioactive isotopes, particularly those used in nuclear medicine. In progress studies are presented.
对于用于诊断和治疗医学应用的放射性同位素的生产需求日益增长。然而，使用（n，γ）或（γ，n）反应生产的放射性同位素，由于相同元素的靶材料丰度高，通常会导致样品的比活度（放射性∕克）较低。有效去除同位素杂质的一种方法是电磁质量分离。加拿大粒子与核物理国家实验室（TRIUMF）已建造了一个离子源测试设施，以开发用于纯化放射性同位素，特别是用于核医学的放射性同位素的高强度、高效率、可靠的离子源。本文介绍了正在进行的研究。
