ABSTRACT:
An apparatus, and method, are disclosed for producing a high specific activity of a radioisotope in a single increment of target material, or sequentially within in-series increments of target material, by exposing a targeted isotope in the target material to a high energy photon beam to isotopically convert the targeted isotope. In particular, this invention is used to produce a high specific activity of Mo.sup.99, of at least 1.0 Ci/gm or preferably at least about 10.0 Ci/gm, from Mol.sup.100.
