PROCESS AND APPARATUS FOR THE PRODUCTION OF BI-212 AND A USE THEREOF

摘要

A process for producing substantially radio-impurity-free Bi-212 is disclosed. An acidic feed solution containing Pb-212 is contacted with an extraction medium to bind the Pb-212 thereto. The extraction medium is rinsed with a second acid solution to remove impurities therefrom, leaving a substantially impurity-free Pb-212-laden extraction medium. The Pb-212 grows on the extraction medium to form Bi-212 by radioactive decay. The Bi-212 is then eluted from the extraction medium with an acid solution to form a substantially radio-impurity-free Bi-212 acid solution. An apparatus for carrying out this process and a process for the therapeutic use thereof are also disclosed.
