It was found that in the preparation of polyurethane sheet piece cross-link (xPU) is less thick Composite plate xPU/BaSO4 and xPU/Bi2O3 because there are composite particles, sheets of BaSO4 and Bi2O3 into preventing contraction of xPU testing highly material x-ray attenuation coefficients are reported from degrade the nest.Color x 2 categories which divided x-ray attenuation coefficient, the linear coefficient (µl) and x-ray mass attenuation (µm) is a value that signifies the ability of x-ray attenuation material. It was found that the concentration is 50 phr composite plates with solid substances and radiation attenuation coefficient values Bi2O3 x-ray linear (µl) with private plate cm-1 composite 8.870 xPU/BaSO4 with x-ray attenuation coefficients linear (µl) with the attenuation coefficient, which cm-1 2.548 x-ray linear (µl) of composite xPU/Bi2O3 is greater than composite sheet is 4 x/BaSO4 xPU.
