Preparation of 64Cu of high specific activity by the reaction 64Zn (n, p)64Cu was investigated. Five grams of zinc oxide were irradiated in JRR-1 reactor for 5 hr. 64Cu produced was separated from zinc by an anion exchange or the combination of organic co-precipitation and anion exchange. About 1 mc of 64Cu with specific activity of more than 2.5×106 mc/g Cu at best was prepared.
The use of an orgnic co-precipitation was useful to reduce processing time.
Some comparisons were made to a Szilard Chalmers process, which was the other method to prepare 64Cu of high specific activity.
