Abstract
Fission-based 99 Mo/ 99m Tc generators have undergone evolutionary changes since they were first manufactured at the Lucas Heights Laboratories in the late 1960s for the Australian nuclear medicine community. This study is aimed at understanding the chemistries which influence the behaviour of the heterogeneous molybdenum-alumina system in a chromatographic generator. The quality of sodium pertechnetate derived from a dry-bed generator is enhanced when compared with the traditional wet-bed technologies. Data is presented which compare the extent of 99Mo desorption from both wet and dry-bed chromatographic generators. The expiration times for sodium pertechnetate based on 99Mo breakthrough are significantly greater for the recently developed dry-bed generators.
