¹²⁵I生产工艺研究进展与展望

摘要: ¹²⁵I是一种重要的医用放射性核素，由于其半衰期较长（T_1/2=59.4 d），γ射线能量低、无β辐射，对人体组织产生的辐射损伤小等优点，使其在生物医学、放射免疫体外诊断和近距离植入治疗肿瘤等方面得到了广泛应用。本文简要介绍¹²⁵I的生产原理、国内外生产工艺研究现状、国内市场需求，并展望¹²⁵I的生产前景。

Abstract: Iodine-125(¹²⁵I) is one of the most attractive and significant radionuclide that is widely used in biomedical, radioimmunoassay in vitro diagnosis and brachytherapy for tumors owing to its favorable nuclear characteristics, including low energy X-ray, no β-ray, less radiation damage. In this paper, the process and current status of ¹²⁵I production technology, demand of domestic market and the prospect of ¹²⁵I were briefly introduced.
