MONTE CARLO EVALUATION OF THE RADIATION SHIELDING EFFICIENCY OF LAMINATED COMPOSITES UNDER ELECTRON AND PHOTON IRRADIATION
The heterogeneity effect on the shielding efficiency of laminated composites under electron and gamma irradiation of moderate (~MeV) energies was studied. The effect was quantified, by means of Monte Carlo method, in terms of the asymmetry of the bimetallic dual layer system’s AlW shielding efficiency depending on the direction (Al–W vs. W–Al) of both electron and photon irradiation. The charged particles and bremsstrahlung radiation transport was simulated for electron irradiation of the 9-layer composite test sample fabricated by the vacuum hot rolling solid phase welding of Ti–Ni–Cu–Nb–Cu–(W–Cu)2 layers. Dose and photon kerma rates behind the laminated shielding were calculated and the prospects of its application under severe constraints both on shielding weight and dimensions were substantiated.
