采用一维扩散模型研究了室内、子体和及其子体平衡因数 (FTh)的分布规律。讨论了FTh随墙面析出率、室内通风状况和空气含尘状况的变化。介绍了通过选取合适的FTh,由暴露量直接估算子体所致有效剂量的方法。
One-dimensional diffusion model was used to study the distribution of 平, and 其 and their daughter balance factor (FTh). The change of FTh with the rate of wall precipitation, indoor ventilation and airborne dust were discussed. A method to directly estimate the effective dose of popcorn by the exposure by selecting the appropriate FTh is presented.
