Cyclotron production of high-purity 123I

Excitation functions, thin-target and cumulative yields for the proton-induced reactions on 127/I targets were measured in the 67.5- to 5.3-MeV energy region. These results were used primarily to define the proton-energy ranges and target thicknesses to optimize radionuclide yields and purities for 123I production from its 2.08 I-h 123Xe parent. Other reactions producing radioxenons of interest in nuclear medicine (i.e. 36.406-d 127Xe, 17.3-h 125Xe, 20.1-h 122Xe, and 38.85-min 121Xe), were also measured. These results are compared to other previously reported values. (author)
