1. A process for the production of radiostrontium, said process comprising the following steps: bombarding a target of metallic rubidium by a beam of accelerating charged particles,  melting said irradiated target of metallic rubidium,  immersing a sorbing material into said melt of metallic rubidium,  extracting radiostrontium by sorption on the surface of said sorbing material, and  using, as said sorbing material, a material selected from the group consisting of heat-resistant metals, metallic and silicon oxides, said material being inert with respect to said rubidium, and  extracting the resultant radiostrontium.  the temperature of molten rubidium is set to be close to the optimum one for the desorption of radiostrontium within the range of from 220 deg.C. to 270 deg.C. 2. The process as claimed in claim 1, wherein the temperature of said sorbing material is set to be close to the optimum one for the sorption of radiostrontium within the range of from the melting point of metallic rubidium to 220 deg.C., and
