AbstractAbstract
[en] A method for the production of fluorine-18 in a research reactor, from irradiated lithium carbonate, is described. Fluorine-18 is separated from impurities in a alumina column, which is an appropriate procedure for its production as a carrier-free radioisotope for oral administration. Characteristics of the product, when fluorine is separated from irradiated target in an usual alumina column, are compared with those when fluorine is separated in a previously calcined(10000C) alumina column: Yields of chemical separation and chemical forms of radioisotope obtained are studied. Fluorine elution is investigated for several eluant concentrations and the use of a lower concentrated eluant is emphasized. Purity degree of fluorine-18 solutions separated. A routine production procedure is determined by irradiating enriched lithium carbonate (95% 6Li). Theoretical yields are compared with fluorine-18 production yields obtained in several irradiations

Descrevem-se os aspectos relativos a producao do fluor-18 em reator de pesquisa; a partir de carbonato de litio. Estuda-se a separacao do fluor-18 em coluna de alumina, que e um metodo simples e eficiente para a obtencao deste radioisotopo livre de carregador para uso oral. Verificam-se as caracteristicas do produto obtidg$ separando-se o fluor em coluna de alumina tratada pelo metodo convencional, a frio. Comparam-se essas caracteristicas com aquelas do fluor separado em coluna de alumina calcinada a 10000C. Estudam-se os rendimentos do processo de separacao e as formas quimicas do radioisotopo produzido. Determinam-se as condicoes de eluicao do fluor-18, usando-se eluente em diferentes concentracoes e destaca-se a vantagem de se usar aluente mais diluido. Mostram-se os teores de pureza do produto obtido quando se separa o fluor-18 em coluna de alumina previamente calcinada. Determina-se uma rotina de producao a partir do carbonato de litio enriquecido no isotopo 6Li e calculam-se as quantidades teoricas produzidas que sao comparadas com os valores experimentaisOriginal Title
