99mTc generator preparation using (n, γ)99Mo produced using natural molybdenum

The Mo-99 is a widely used radioisotope in Korea. To fulfill the demand, we are producing Mo-99 using a specially designed and fabricated rig containing MoO3 target. We are using natural molybdenum so far. But considering the utilization of the enriched molybdenum to increase the specific activity further, we desire the realization of PZC with (n, γ)Mo-99 as early as possible. To make the generator loading facility, we are in progress of construction work for the related hot cell facilities. (author)
