During the purification of radioisotopes, decay periods or time dependent purification steps may be required to achieve a certain level of radiopurity in the final product. Actinum-225 (Ac-225), Silver-111 (Ag-111), Astatine-211 (At-211), Ruthenium-105 (Ru-105), and Rhodium-105 (Rh-105) are produced in a high energy proton irradiated thorium target. Experimentally measured cross sections, along with MCNP6-generated cross sections, were used to determine the quantities of Ac-225, Ag-111, At-211, Ru-105, Rh-105, and other co-produced radioactive impurities produced in a proton irradiated thorium target at Brookhaven Linac Isotope Producer (BLIP). Ac-225 and Ag-111 can be produced with high radiopurity by the proton irradiation of a thorium target at BLIP.
在放射性同位素的纯化过程中，可能需要半衰期或时间依赖的纯化步骤来达到最终产物的一定放射纯度。锕-225（Ac-225）、银-111（Ag-111）、砹-211（At-211）、钌-105（Ru-105）和铑-105（Rh-105）是在高能质子辐照的钍靶中产生的。实验测量的截面以及 MCNP6 生成的截面用于确定在布鲁克海文 Linac 同位素生产者（BLIP）的质子辐照钍靶中产生的 Ac-225、Ag-111、At-211、Ru-105、Rh-105 和其他共生产放射性杂质的数量。Ac-225 和 Ag-111 可以通过在 BLIP 用质子辐照钍靶来以高放射纯度生产。
