“…Boron bombardment of silver 50 leads to 116 Te which rapidly decays to 116 Sb. The light isotopes of iodine ( 123,124,125 I) are widely used in the preparation of many radiopharmaceuticals and can be prepared from 125 Te by proton bombardment. Excitation functions, as a function of proton beam energy, have now been calculated 51 which should greatly facilitate the optimisation of conditions for the production of specific isotopes.…”
