Preparation of {sup 82}Sr from a metallic Rb target in a 100 MeV proton beam

The medical radioisotope {sup 82}Sr was obtained by irradiating a metallic Rb target with protons accelerated to an energy of 100 MeV. The yield of {sup 82}Sr was chemically isolated by dissolving metallic Rb in isobutanol with subsequent conversion to the chloride, distillation of the organic phase, and removal of Rb{sup +} on cation exchanger. The product has high radionuclidic purity.
