FIELD: power industry.
SUBSTANCE: for using in the technology of obtaining radioactive isotopes the start target composition on the basis of radium includes radium and lead oxide (diluter). Method for obtaining start composition on the basis of radium consists in co-deposition of radium carbonate with lead carbonate from water solutions of their soluble salts with solutions of water-soluble carbonates and calcination of the obtained deposit at temperature of more than 350°C.
EFFECT: group of inventions allows increasing specific yield of radium activation products.
