Claims (1)

Способ очистки материала от радиоактивных загрязнений включает в себя стадию контактирования очищаемого материала с растворяющей композицией для растворения содержащегося в материале загрязнения. Композиция содержит разбавленный раствор, содержащий приблизительно 0,05 моль этилендиаминтетрауксусной кислоты, приблизительно 0,1 моль карбоната, приблизительно 10 г на 1 л пероксида водорода и эффективное количество едкого натра для регулирования pH композиции до примерно 9 - 11. Способ также включает в себя стадии отделения растворяющей композиции, содержащей растворенные в ней загрязнения, от обрабатываемого материала и извлечения растворенных загрязнений из отделенной от обрабатываемого материала растворяющей композиции. Также предложена композиция для растворения присутствующих в материале радиоактивных загрязнений, содержащая разбавленный раствор с основным значением pH, эффективное количество хелатного агента и карбоната, достаточные для растворения радиоактивных загрязнений.The method of cleaning material from radioactive contamination includes the stage of contacting the material being cleaned with a dissolving composition for dissolving the contamination contained in the material. The composition contains a dilute solution containing approximately 0.05 mol of ethylenediaminetetraacetic acid, approximately 0.1 mol of carbonate, approximately 10 g per 1 l of hydrogen peroxide and an effective amount of caustic soda to adjust the pH of the composition to about 9 to 11. The method also includes separating the dissolving composition containing the impurities dissolved in it from the material being processed and extracting the dissolved impurities from the dissolving composition separated from the material being processed. Also proposed is a composition for dissolving radioactive contaminants present in the material, containing a dilute solution with a basic pH value, an effective amount of a chelating agent and carbonate, sufficient to dissolve the radioactive contaminants.
