- Direct production of 99mTc-Technetium using low energy cyclotrons and radionuclidic purity: our results so far using natMo-MolybdenumPublication . Metelo, Luís Francisco; Costa, Pedro; Cunha, L.; Jonhson, R.; Matei, L.; Gelbart, W.; Obermair, J.; Artner, C.; Lass, P.; Currie, G.; Craciun, L.; Niculae, D.; Carmo, S.; Alves, F.; Botello, M.Despite the global crisis concerning 99mTc delivering to Nuclear Medicine Departments there isn’t yet a reliable solution. The cyclotron direct production of 99mTc, using the 100Mo(p,2n)99mTc nuclear reaction is our attempt to approach the problem, aiming to become efficient, reliable and sustainable from points of view as reducing drastically the radioactive waste being produced and becoming beneficial for all the involved parts. Between several critical factors, radionuclidic purity of cyclotron-produced 99mTc is being pointed as an issue of concern.
- Using low energy medical cyclotrons to produce 99mTc - TechnetiumPublication . Metello, L. F.; Gelbart, W.; Cunha, L.; Carmo, S.; Artner, C.; Alves, F.This paper refers to work in progress, addressing the global trouble in delivering 99mTc to Nuclear Medicine Departments, Aiming to develop an efficient, safe and economical way to directly produce Technetium 99metastable (99mTc) using lowenergy - so-called “medical” - cyclotrons. The present delivery strategy has intrinsic limitations because it is not only based on old nuclear reactors, but also limits the weekly agenda workflow. Our approach is distinct, and is based on the broad distribution network of the low energy cyclotrons and the accessibility of Molybdenum 100 (100Mo) as the target material, so the system here presented, is not based on the use of Nuclear Reactors and highly enriched (or even low enriched) Uranium 235 (235U), but entirely complying with the current international trends and directives, concerning the need to reduce the use of this potential highly critical target material. The direct production technique is based on the nuclear reaction 100Mo(p,2n)99mTc whose production yields have already been widely documented. The 99mTc is produced in a routine, reliable and efficient manner that, remaining always flexible, entirely blends with established protocols.
