FIELD: manufacture of radio-absorbing materials; application of coats on medical, exploratory and domestic articles. SUBSTANCE: proposed method consists in application of radio-absorbing material on surface to be protected; coat consists of several layer; each layer is dried separately; at least one layer includes split rings made from electric conducting material and inserted before drying; rings have different diameters. EFFECT: enhanced efficiency; extended range of wave length. 2 cl, 1 dwg, 2 tbl, 1 ex
