FIELD: radiation safety. SUBSTANCE: invention provides sorbents prepared from vegetable lignocellulose material, which can be used for cleaning liquid media (oil- field middle water, agricultural products, in particular milk), reclaiming land and agricultural areas polluted by radionuclides. Oatstraw is mechanically ground on vibration mill to powder state and then treated for 2-5 h with 0.1-2 N sodium hydroxide solution at atmosphere pressure and boiling temperature of mixture 100-105 C. EFFECT: reduced price and improved environmental purity of product. 1 tbl, 5 ex
