The exposure of concrete to gamma radiation gives rise to a set of physical and chemical processes over multiple length scales, from molecular to bulk. The literature includes a number of bulk-scale studies which report the radiogenic heating of concrete and the loss of water (unbound, physically-bound, and/or chemically-bound) due to irradiation. This paper mechanistically quantifies observations by these studies, and presents a continuum framework to model the effects of gamma photons on concrete. A basis is presented for comparing otherwise disparate results in the literature for radiolysis rates. The Stefan–Boltzmann Law, adapted to include a gamma heat source term, reasonably describes radiogenic heating in concrete specimens. In multiple studies, the primary mechanism for dehydration is the loss of liquid water in the pore network of the cement product, rather than of water which is physically or chemically bound in a solid state.

伽玛辐射与混凝土相互作用的大体积观测量化和建模

混凝土暴露于伽马辐射会在从分子到体积的多个长度尺度上产生一系列物理和化学过程。文献包括大量大规模研究，这些研究报告了混凝土的放射生热和水的损失（未结合的、物理结合的和/或化学结合的）由于辐射。本文机械量化了这些研究的观察结果，并提出了一个连续框架来模拟伽马光子对混凝土的影响。为比较文献中有关辐射分解率的不同结果提供了基础。Stefan-Boltzmann 定律适用于包括伽马热源项，合理地描述了混凝土试样中的辐射加热。在多项研究中，
