На основании проведенных исследований показана возможность получения конструкционного радиационно-защитного композиционного материала, упрочняемого при радиационно-термических нагрузках. Воздействие высоких доз гамма облучения приводит к образованию в цементно-магнетито-серпентинитовом композите однокальциевого феррита СаFe2O4, обладающего высокой физической и рентгеновской плотностью, что определяет радиационное упрочнение композита и повышение его механической прочности вплоть до дозовой нагрузки 10 МГр. При радиационном γ-облучении защитного ...
