摘要

用

211

At标记的放射性药物用于肿瘤的治疗，近年来受到人们的重视。为了获得

211

At，以研究它的物化性质和在生物医学上的应用，我们对用加速器制备

211

At所必需的金属铋靶的制靶条件进行了研究。铋靶制备方法常见有真空熔融法

[1]

、电镀法

[2]

和真空镀膜法等，本文着重介绍了用真空镀膜法制备铋靶的方法。多次实际使用表明，用此法制备的铋靶，性能良好，质量稳定可靠。

Abstract

Methods for preparing Bi targets have been studied to optimize the production of

211

At. A method is emphatically described which is based on vacuum evaporating Bi metae with 99.999% chemical purity onto a copper disk (50×2 mm).

These Cu-supported Bi targets have been bombarded with 27 MeV

-particles from 1 cyclotron. No crackle

puffiness and dropping of target have been found.
