Abstract
Official abstract text for this publication.
Compositions comprising high levels of high specific activity copper-64, and process for preparing said compositions. The compositions comprise from about 2 Ci to about 15 Ci of copper-64 and have specific activities up to about 3800 mCi copper-64 per microgram of copper. The processes for preparing said compositions comprise bombarding a nickel-64 target with a low energy, high current proton beam, and purifying the copper-64 from other metals by a process comprising ion exchange chromatography or a process comprising a combination of extraction chromatography and ion exchange chromatography.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composition for use as a radioactive precursor comprising from 2 Ci to 15 Ci of copper-64 ( 64 Cu), wherein the radionuclidic purity of the 64 Cu is greater than 98.5%. 2 . The composition of claim 1 , wherein the radionuclidic purity of the 64 Cu is greater than 99%. 3 . The composition of claim 1 , wherein the radionuclidic purity of the 64 Cu is greater than 99.5%. 4 . The composition of claim 1 , wherein the radionuclidic purity of the 64 Cu is greater than 99.9%.
