Claims (3)

1. Способ получения препарата на основе стронция-89, заключающийся в облучении оксида природною иттрия быстрыми нейтронами по реакции (n, р), растворении полученной смеси изотопов в кислоте и выделении конечного продукта экстракцией иттрия, отличающийся тем, что оксид иттрия до облучения термически обрабатывают в вакууме при температуре не менее 1200oC в течение не менее двух часов.1. The method of obtaining a preparation based on strontium-89, which consists in irradiating natural yttrium oxide with fast neutrons by the reaction (n, p), dissolving the resulting mixture of isotopes in acid and isolating the final product by yttrium extraction, characterized in that the yttrium oxide is thermally treated in vacuum at a temperature of at least 1200 o C for at least two hours. 2. Способ получения препарата на основе стронция-89 по п.1, отличающийся тем, что оксид природного иттрия перед термической обработкой прессуют в брикеты. 2. A method of obtaining a preparation based on strontium-89 according to claim 1, characterized in that the natural yttrium oxide is pressed into briquettes before heat treatment. 3. Способ получения препарата на основе стронция-89 по п. 2, отличающийся тем, что оксид иттрия после прессования, но до вакуумной термической обработки предварительно обжигают на воздухе при температуре 800-1200oC, а после вакуумной термической обработки удаляют поверхностный слой брикета.3. A method of obtaining a preparation based on strontium-89 according to claim 2, characterized in that the yttrium oxide after pressing, but before vacuum heat treatment, is pre-fired in air at a temperature of 800-1200 o C, and after the vacuum heat treatment the surface layer of the briquette is removed .
