Investigation of the radiation shielding efficiency of laminated composite materials by means of computer simulation methods

 The heterogeneity effect on the shielding efficiency of laminated composites under electron and gamma-irradiation of moderate (~MeV) energies was studied [23(2014)]

 The effect was quantified, by means of Monte Carlo method, in terms of the asymmetry of the model bimetallic dual layer system's AlW shielding efficiency subject to the direction (Al→W vs. W→Al) of both electron and X-ray/gamma irradiation.

 The charged particles and bremsstrahlung radiation transport was simulated using PENELOPE and RaT 3.1 Monte Carlo codes for electron irradiation of 9-layer TiNiCuNbCu(WCu)2 composite test sample fabricated in the NSC KIPT Inst. of Solid State Physics, Material and Technologies by means of vacuum hot rolling solid phase welding process. Total Ionization Dose (TID) and photon kerma rates behind the laminated shielding were calculated and the prospects of this innovated composite material application under severe constraints both on shielding weight and dimensions were physically substantiated.
