Depth-dose profiles of electron radiation in continuous and discontinuous materials of water, plastic and food-like dummy irradiated by 10 MeV electron beam have been evaluated based on Monte Carlo simulations and measurements. In the discontinuous mediums, material layers were separated by air gaps. The discrepancy of the absorbed doses in the continuous and discontinuous materials is within 12%. No significant effect of the discontinuity on the main characteristics such as practical range and double-sided optimal thickness was found. The results indicated that the double-sided optimal thicknesses of the materials can be increased to greater than the reference values of 8.5–8.8 g/cm\(^2\) to improve the efficiency of the irradiation process.

已经基于蒙特卡罗模拟和测量评估了由 10 MeV 电子束照射的水、塑料和类食物假人的连续和不连续材料中电子辐射的深度剂量分布。在不连续介质中，材料层被气隙隔开。连续材料和非连续材料吸收剂量的差异在12%以内。没有发现不连续性对实用范围和双面最佳厚度等主要特性的显着影响。结果表明，材料的双面最佳厚度可以增加到大于参考值 8.5-8.8 g/cm \(^2\)以提高辐照过程的效率。
