Abstract

Polymers are widely used in disposable medical devices that must fulfill strict safety and effectiveness standards, including radiation sterilization. The effectiveness of electron-beam (e-beam) sterilization depends critically on the uniformity of the absorbed radiation dose distribution. This study investigates the absorbed dose depth distribution in 11 industrial polymer materials irradiated by a 10 MeV e-beam accelerator (BRIN specifications) using PUFFIn-based Monte Carlo simulations. Target materials were modeled as 100 × 25.5 × 10 cm blocks with observation points spaced 1 mm along the z-axis. The percentage depth dose (PDD) curves show that maximum dose depth Zmax ranges from 1.85 to 3.05 cm across the studied polymers. High-density materials such as Polycarbonate (PC, 1.35 g/cm3) exhibit shallower penetration (Zmax = 1.85 cm), whereas low-density materials like Polyolefin Elastomer (POE, 0.87 g/cm3) allow deeper penetration (Zmax = 3.05 cm). At equivalent densities, materials with higher effective atomic numbers (Zeff) tend to show slightly higher maximum doses (Dmax), likely due to enhanced electron interaction and backscattering probabilities. These quantitative insights provide a scientific basis for optimizing industrial e-beam processing parameters and material selection for medical device manufacturing.
