METHOD OF OBTAINING SILVER RADIOISOTOPES WITHOUT CARRIER Russian patent published in 2009 - IPC G21G1/10

Abstract RU 2344504 C1

FIELD: technological processes; chemistry.

SUBSTANCE: metal cadmium is used as target substance and irradiated by high-energy protons. Target substance is separated by distillation in hydrogen atmosphere. Nuclear reaction and transformation products are collected on quartz sand surface. Obtained radioactive sample is placed into start zone of quartz thermochromatographic column. The sample undergoes high-temperature chemical processing in the presence of reagent, with transfer of obtained volatile compounds. Volatile compounds are precipitated on the column walls at certain temperatures. Phosphor or arsenic vapours are used as reagent.

EFFECT: enhanced radiochemical purity of silver radioisotopes.
