Cyclotron production of using natural Zn & enriched targets
- Conference date: 26–29 August 2012
- Location: Playa del Carmen, México
Copper-61 ( ) shares with certain advantages for PET diagnostic imaging, but has a shorter half-life (3.4hr vs. 12.7hr) and a greater probability of positron production per disintegration (61% vs. 17.9%). One important application is for in vivo imaging of hypoxic tissue. In this study was produced using the reaction on natural Zn or enriched targets. The enriched (99.82%) was electroplated onto high purity gold or silver foils or onto thin Al discs. A typical target bombardment used 30μA; at 11.7, 14.5 or 17.6MeV over 30-60min. The (radiochemical purity of >95%) was separated using a combination of cation and anion exchange columns. The target material was recovered after each run, for re-use. In a direct comparison with enriched -target results, production using the cheaper nat Zn target proved to be an effective alternative.
