Abstract: A method for producing a fraction of xenon radioisotopes, comprising the steps of dissolving enriched uranium targets forming a slurry and a gaseous phase containing xenon radioisotopes, isolating the xenon radioisotopes using zeolite doped with silver, preferably chosen from the group consisting of aluminosilicates doped with silver, titanosilicates doped with silver and mixtures thereof, and recovering the fraction of xenon radioisotopes, in particular Xe-133.
Abstract: A method for producing an iodine radioisotopes fraction, comprising the steps of dissolving enriched uranium targets forming a slurry, filtering said slurry, absorbing salts of iodine radioisotopes on an aluminium resin doped with silver and recovering said iodine radioisotopes fraction, is disclosed. The recovery of the iodine radioisotopes fraction, in particular of I-131, comprises washing the aluminium resin doped in silver using a solution of NaOH and eluting of iodine radioisotopes by a solution of thiourea, and collecting an eluate containing said iodine radioisotopes in a thiourea solution.
Abstract: The use of titanium oxide as a stationary phase in a radio-isotope generator device, wherein said titanium oxide comprises particles having a d50 comprised between 10 and 350 ?m, and having a BET specific surface area comprised between 30 and 300 m2/g, preferably greater than 60 m2/g, and of a generator comprising the stationary phase used.
