Towards the production of carrier-free 99Mo by neutron activation of 98Mo in molybdenum hexacarbonyl -Szilard-Chalmers enrichment

The effects of the irradiation time, the aqueous phase composition and the irradiated mass were studied with a focus on the chemistry involved. Stable extraction yields of 20% were obtained with enrichment decreasing with target decomposition. Improved enrichment requires decreased decomposition.
