Abstract  

With the use of an 80 MeV isochronous cyclotron, a preparation procedure for123I is outlined. The nuclear reaction applied in the process is:

A liquid target is irradiated and a continuous gas-liquid extraction of parent123Xe is performed. After a short growth time the daughter123I is dissolved and treated for various applications. The radionuclidic purity is very high, only125I is detectable with a maximum of 0.2% to the end of the preparation process. In this production of carrier-free123Xe and123I, the major chemical problem consists of a separation into microquantities. Attempts to find a solution to various technical problems are also described.
