摘要随着科学技术的发展，核与辐射广泛应用于工业、军事、医学等领域，随之而来的辐射暴露也越来越多。当前核反应堆和核潜艇的运行、肿瘤放射治疗、太空飞行、核装置爆炸以及核泄漏等均涉及到中子辐射的暴露。中子是一种高传能线密度（Linear Energy Transfer，LET）射线，电离密度大，能量沉积严重，会对生物体造成严重的损伤效应。因此在辐射暴露事件中，进行中子辐射损伤效应的评估至关重要。相对生物学效应（Relative Biological Effectiveness，RBE）就是常用的估算中子暴露风险的一种手段。特定辐射条件下的RBE值取决于自身暴露条件，如中子本身的能量、剂量和剂量率以及所涉及的组织或细胞类型等，本文将从这几方面展开对中子RBE值的讨论。此外，当前绝大部分辐射暴露场均为混合场，因此充分考虑混合场中的其他成分所产生的影响同样重要。
