In the radiation protection application, the metal-polymer composites have been developed for theirradiation shielding properties. In this research, the elastomer composites doped by 10 mm and100nm sizeof lead, bismuth and tungsten particles as filler with 30 and 60 wt percentages were prepared. To surveythe shielding properties of the polymer composites using gamma-ray emitted from 152Eu and 137Cssources, the gamma flux was measured by using NaI(Tl) detector, then the linear attenuation coefficientwas calculated. Also, the Monte Carlo simulation (MCs) method was used. The results showed a directrelationship between the linear attenuation coefficients of the absorbent and filler ratio. Also, thedecrease in the particle size of the shielding material in each weight percentage improved the radiationshielding features. When the dimension of the particles was in the order of nano-size, more attenuationwas achieved. At low energies used for medical diagnostic X-ray applications due to the predominance ofthe photoelectric effect, bismuth and lead were suitable selection as filler.
