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 Mo99, of at least 1.0 Ci/gm or preferably at least about 10.0 Ci/gm, from Mo100.
Claims10
A method of producing a product isotope by isotopic conversion reaction comprising:
- providing a target;
- directing an electron beam having intensity of at least 50 microamps/cm2 onto a converter to generate a photon beam having photons of energy of at least 8 MeV;
- and
- directing the photon beam onto the target to isotopically convert at least a portion of the target to the product isotope.
