The Effect of the Concentration Chang of Reinforcing Materials on the Values of Some Theoretical Attenuation Parameters

Ahmed Fadhil Mkhaiber, Abdulraheem Dheyaa Ibrahim


In this paper, some theoretical attenuation  parameters was calculated for shields  made up of composite materials basis polymer (Epoxy )  with added materials (C,Ni,PbO,Bi) with different concentrations (10,20,30,40,50)wt% , where the effect of concentrations variation on the attenuation coefficients values , effective atomic number and shields density has been studying. The computer program code X-Com was used to calculate the attenuation parameter values at different energies (0.662,1.173,1.332)MeV .Results shows that there is a clear change in the values of these parameters with the change of concentration ratios.
