125I Production Technology: Current Status and Future Perspective

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.
