摘要

Several previous works have shown that PZC materials as a molybdenum adsorbent afford a promising prospect for the future production of (n, γ)~(99)Mo/~(99m)Tc Generators loaded with irradiated natural molybdenum. This paper evaluates the performance of the (n, γ)~(99)Mo/~(99m)Tc Generators loaded with the high activity molybdenum (190 - 350 mCi, 0.71 Ci/g Mo - 1.31 Ci/g Mo). The performance parameters concerned are the ~(99m)Tc yields, molybdenum breakthrough, and elution profiles. The evaluation will be emphasized on the effects of the use of NaOCl as an oxidizing agent in a saline elution solution and the use of a zirconium solution in the washing step. Preliminary experimental results of dry-bed system generators will also be mentioned.
