摘要

本文讨论了低比活度(9⁰Y [T½= 64.1 h, Eβ-(max) = 2.28 MeV]在制备用于治疗浅表皮肤状况，特别是瘢痕疙瘩的放射性贴片源中的应用。钇-90的比活度为688±41 MBq/mg，放射性核素纯度为99.9%。建立了一种简单、可重复的制备放射性贴片源的方法，每个源中加入92±8 MBq的90Y，放射性分布均匀，无表面污染，几乎没有放射性浸出。对顽固性瘢痕疙瘩的初步调查显示了良好的结果。

Utility of low specific activity 90Y produced in a medium flux research reactor in the preparation of radioactive patch for the treatment of skin ailments

The article discusses the application of low-specific-activity ⁹⁰Y [T_½ = 64.1 h, E_β-(max) = 2.28 MeV] in the preparation of radioactive patch sources for the treatment of superficial skin conditions, particularly keloids. Yttrium-90 was produced with 688 ± 41 MBq/mg specific activity and > 99.9% radionuclide purity in a medium flux research reactor. A simple and reproducible method was established to prepare radioactive patch sources, incorporating 92 ± 8 MBq of ⁹⁰Y in each source with uniform distribution of radioactivity, without any surface contamination and almost no leaching of radioactivity. Preliminary investigations with developed sources in recalcitrant keloids showed promising outcome.
