Preparation of Mo-99 from Mo-100

A production process was put forward for recovery of molybdenum from wastes of nuclear fuel reprossessing and for subsequent preparation of Mo-100 tar gets to be used for generating Mo-99 and Tc-99m. In this process molybdenum is recovered from nitric acid solutions by sorption on ANKB-2 ampholyte an d then purified by sublimation. The final form is molybdenum trioxide or me tallic molybdenum. The degree of molybdenum recovery is >90%. Up to 3 Ci of Mo-99 can be prepared by 24-h irradiation in a high-current cyclotrons of 1 g of molybdenum recovered from wastes of nuclear fuel reprocessing.
