Studies on preparation of 64Cu using (n,γ) route of reactor production using medium flux research reactor in India

64 Cu (t 1/2 12.7 h) is a versatile radionuclide owing to its unique decay scheme and exhibits three types of decay electron capture (41%), β − (40%), β + (19%) that is useful in nuclear medicine applications. Different batches of natural copper oxide (CuO) and 99.9% enriched 63 CuO targets were irr...

Description
Summary:64 Cu (t 1/2 12.7 h) is a versatile radionuclide owing to its unique decay scheme and exhibits three types of decay electron capture (41%), β − (40%), β + (19%) that is useful in nuclear medicine applications. Different batches of natural copper oxide (CuO) and 99.9% enriched 63 CuO targets were irradiated in research reactors at a neutron flux of 6.6 × 10 12  n cm −2  s −1 for duration of 3 days. Irradiated samples dissolved in hydrochloric acid solution were measured in HPGe-MCA system, the activity of 64 Cu, co-produced radionuclide impurities and radionuclide purity was determined. Average specific activity of 254 GBq 64 Cu per g Cu and ~348 GBq 64 Cu per g Cu was recorded at the end of irradiation from natural and enriched CuO targets, respectively.
