METHOD OF PRODUCING RADIOPHARMACEUTICAL PREPARATION "ASTATINE-211" Russian patent published in 2016 - IPC A61K101/00 A61P35/00 

FIELD: chemistry; medicine.

SUBSTANCE: present invention relates to conversion of chemical elements and radiation sources for medical purposes, particularly to a method of producing radiopharmaceutical preparation “Astatine-211” from an irradiated target, which includes subliming radionuclide at temperature 700÷850 °C for 4÷6 minutes, with its deposition in low-alkali buffer saline solution with pH 7.5-9, where target is Bi of natural isotopic composition that is irradiated by αparticles with energy 29÷31 MeV.

EFFECT: invention provides considerable reduction of time for obtaining stable forms of ²¹¹At, trophic to thyroid gland, reduction of radiation exposures on personnel, involved in manufacturing of preparation, and increased efficiency of synthesis of preparation.
