Bismuth 213
WebBismuth-213 is used in cancer therapy, specifically targeted alpha therapy (TAT). It has a high level of energy producing 8.4 MeV and has a half-life of 46 minutes. Caesium-131 Caesium-131 provides soft x-rays which makes it suitable for brachytherapy. It has a half-life of 9.7 days. Caesium-137 Caesium-137 has a lower level of energy. WebRecent reviews of the use of 212 Bi and 213 Bi in radiotherapy have been published. 224–231 The DOTA chelate, conjugated to appropriate biomolecules for delivery to the tumor sites, appears to be the most appropriate chelate for 212/213 Bi, although some researchers are having success with the sterically hindered DTPA analog, CHX-DTPA ( …
