METHOD FOR RADIOSTRONTIUM PREPARATION (VERSIONS) Russian patent published in 2009 - IPC G21G1/10 

FIELD: physics, nuclear physics.

SUBSTANCE: group of inventions is related to the field of nuclear technology and radio chemistry and is intended for preparation and extraction of radioactive isotopes for medical purpose. Method for preparation of radiostrontium includes radiation of target with flow of accelerated charged particles. Inside target shell there is metal rubidium. After target radiation rubidium is melted inside target shell. Extraction of radiostrontium from liquid rubidium is done by surface sorption of different materials that contact with liquid rubidium. Sorption is carried out at the temperature of sorbing surface of 275-350°C. Sorbing surface is internal surface of radiated target shell. After performance of sorption rubidium is removed from target shell. Then radiostrontium is washed from internal surface of target shell by dissolvents.

EFFECT: increased efficiency of radiostrontium preparation and simplification of technology in case of its extraction from large mass of liquid metal rubidium by sorption directly on internal target shell.
