Summary
KIRAMS has developed a reliable wet-extraction method to produce high-purity astatine-211 (211At) via α-irradiation of 209Bi targets. The process effectively removes metallic impurities, yielding 454–817 MBq of chemically pure 211At at pH 5–6 with confirmed radionuclidic identity and minimal contamination. This method ensures high radiochemical purity and labeling efficiency, making the product suitable for targeted alpha therapy applications.
