摘要:

与反应堆相比,加速器生产放射性同位素具有比活度高、半衰期短的特点,且多为发射β+或单能γ射线的缺中子核素。作为制备放射性同位素的重要方式之一,加速器核素研制在进入新世纪后作用与地位日益突出。本文简要介绍了我国加速器同位素的研制与应用情况,并对我国加速器同位素存在的问题及应用前景进行了展望。

Abstract:

Compared with the isotopes generated by nuclear reactor, the isotopes prepared by accelerator always show high specific activity and short half-life period. And most of such isotopes always were neutron-deficient nuclides, giving β+ or single energy γ ray. As one of the most important methods preparing radionuclides, the preparation of isotopes by accelerator has attracted more and more attention from the beginning of 21th century. The development of the preparation and application of the accelerator isotopes were briefly introduced in China. In addition, the forecast of the accelerator-isotope prospect were drawn.
