Optimizing non‐Pb radiation shielding materials using bilayers

Purpose: The objective of this study was to demonstrate that the weight of non‐Pb radiation shielding materials can be minimized by structuring the material as a bilayer composed of different metal‐powder‐embedded elastomer layers. Methods: Measurements and Monte Carlo (MC) calculations were performed to study the attenuation properties of several non‐Pb metal bilayers over the x‐ray energy range 30–150 keV. Metals for the layers were chosen on...
