ИСТИНА

The invention relates to the production of radiostrontium. The problem to be solved by the invention is the extraction of radiostrontium from a large pool of liquid metallic rubidium to improve the efficiency of radiostrontium production and simplify the technology. Sorption is carried out directly on the inner surface of the target shell at a temperature of 275 to 350.degree. C., or by means of extraction of radiostrontium from circulating rubidium via sorption on the heated surface of a trap at a temperature of 220 to 350.degree. C., or by means of filtering liquid rubidium through a filtering unit made of a porous material resistant to liquid rubidium metal.
