dc.description.abstract99mTc is the most widely applied medical radioisotope in the world, especially for cancer diagnosis procedures. It is provided by 99Mo radioactive decay, which is one of the fission products of irradiated uranium by nuclear reactors. At main production centers, 99Mo chemical processing line up different steps to separate it from other fission products, depending on features of targets or local requirements. In this work, two new routes (MR1 and MR2) for 99Mo purification are presented, called MR1 and MR2, can be set up in the Brazilian Multipurpose Reactor project (RMB). In the first studied route, 99Mo purification initiated by eluting the solution through a Dowex 1x8 resin chromatography column, followed by a second step using a Chelex resin column and finally, the process was finished using an alumina column. For a second route, the first step is also performed with a Dowex 1x8 column, followed by a second separation step using alumina column, and lastly, a sublimation process was carried out in a tubular oven under programmed conditions. The final yield for the MR1 route has reached 84.4% and the overall time process about 7 hours, by contrast, MR2 route came to 75.3% in 9 hours.pt_BR
