Deformation-Aware Monte Carlo Assessment of a Bi2O3/Thermoplastic Polyurethane Shielding Surrogate Under Tensile Strain and Local Thickness Loss
Flexible shielding polymers may undergo geometric thinning during tensile use or localized damage, but flat-sheet attenuation measurements cannot resolve the resulting spatial loss of protection. A radiation-transport surrogate comprising 60 wt% thermoplastic polyurethane and 40 wt% Bi2O3 (modeled density, 1.835 g cm−3...
