采用氧化铊靶和15MeV的氘束,通过~(203)Tl(d,2n)~(203)Pb核反应,产生出放射性同位素~(203)Pb。将辐照过的氧化铊靶经过一系列的放化分离程序,可以获得高纯的~(203)Pb示踪剂,铊的含量为～1μg/ml(最终产品为10ml)。~(203)Pb的化学回收率为71±5％。在本实验辐照条件下,辐照停止时~(203)Pb的核反应产额为180±36μCi/μA·h。
The radioactive isotope (203) Pb was produced by ~ (203) Tl (d, 2n) ~ (203) Pb nuclear reaction using a thallium oxide target and a 15 MeV deuterium beam. The irradiated target of thallium oxide was subjected to a series of radiochemical separation procedures to obtain highly purified 203 Pb tracer with a thallium content of ~ 1 μg / ml (final product: 10 ml). The chemical recovery of ~ (203) Pb was 71 ± 5%. Under the experimental irradiation conditions, the yield of ~ (203) Pb nuclear reaction at irradiation termination was 180 ± 36μCi / μA · h.
