Abstract

Present work describes the construction and results of a new81Rb production target system using highly enriched82Kr (99.95%) gas target material. The method yields a carrier-free product of highest activity and highest possible purity. It allows complete recovery of the expensive target material by freezing and avoids tedious chemical separation procedures. The remote-controlled target system has been constructed and functions extremely well.81Rb is used for the preparation of a new type of81Rb−81mKr generator with a capacity of approximately 60 mCi for use in nuclear medical diagnostic (lung ventillation studies and angioscintigraphy).
