Abstract
In this paper, the rationality of boundary conditions that assume radon concentration at the surface of a concrete slab to be zero, or radon concentration at an infinite point in air to be zero, are discussed in the calculations of radon concentration and surface exhalation rate from a concrete slab. Expressions to calculate radon concentration and surface exhalation rate in indoor concrete slab are given for both boundary conditions.
摘要
本文在计算混凝土板中氡浓度和表面析出率时，讨论了假定混凝土板表面氡浓度为零或空气中无限远处氡浓度为零的边界条件的合理性。针对这两种边界条件，给出了计算室内混凝土板中氡浓度和表面析出率的表达式。
