FIELD: medicine, instrumentation engineering, and biology. ^ SUBSTANCE: proposed radioactive source in the form of radioactive yttrium or strontium oxide that can be used, for instance, in medicine for preparation of drugs incorporating radioactive materials, for treatment of oncological diseases, as well as for producing beta-sources used in instrumentation engineering and biologic investigations is solidly capsulated by molten bio-inert glass. Powdered yttrium and strontium oxides are mixed up with glass frit, mixture is applied to metal holder, dried out, and fused; rough surface is produced using definite combination of differently dispersed powders. ^ EFFECT: simplified design, facilitated production of radioactive source; inactivity of radioactive source with respect to organism tissue. ^ 2 cl, 1 dwg, 1 tbl, 1 ex |
