FIELD: physics.
SUBSTANCE: proposed composition comprises epoxy binder, hardener represented by polyamine-amide resin with amine number of 280-310 mg KOH/g, and shielding powder filer made up of the mix of cadmium, cerium, gadolinium, ytterbium and bismuth oxide with the following ratio of components in wt % by: epoxy binder - 14.0-17.0; polyamine-amide resin - 10.0-12.0; cadmium oxide - 31.0-32.0; cerium oxide - 31.5-33.0; gadolinium oxide - 5.0-6.0; ytterbium oxide - 0.5-1.0; bismuth oxide - 3.0-4.0.
EFFECT: higher efficiency of shielding in wide range of X-ray quantum energy.
