FIELD: polymers, radiochemistry. SUBSTANCE: invention relates to polymeric compositions used in nuclear technique, mainly for conditioning radioactive waste with high fluency value of directed radioactivity. Composition has the following components, mas. p. p.: epoxydiane resin, 100; furfurol, 70-100; polyethylenepolyamine, 15-40; shale oil, 50-120; and filling agent, 0-380. Radiation chemical yield in the range of adsorbed doses 500-4 000 Mrad is less by 2-fold as compared with that in the known composition and the rate of radioactive cesium leaching is increased by almost 1 000 times. EFFECT: enhanced effectiveness of composition. 3 tbl
