METHOD OF GAMMA-SPECTROSCOPIC DETERMINATION OF CONTENTS OF CORROSION- ORIGINATED RADIONUCLIDES Russian patent published in 1997 - IPC

Abstract RU 2097791 C1

FIELD: radionuclide control. SUBSTANCE: invention in particular relates to controlling radionuclides in water heat carriers at nuclear power stations. Test sample is successively filtered through block filter elements, the first one being porous membrane and the second one anion-exchange fibers pretreated with 3% versene solution. After filtration, upper and lower block filters are separately subjected to gamma-spectroscopic analysis. Radionuclide content is determined from the sum of measurement results. EFFECT: improved analytical procedure. 1 tbl
