ICRP和美国EPA呼吸道模型的初步比较

Comparison of the Respiratory Tract Models Developed by ICRP and USEPA

比较了国际放射防护委员会 (ICRP)和美国环境保护局 (EPA)推荐的用于评价环境大气中污染物经吸入途径产生的人体危害的呼吸道模型。通过比较两种模型的生理分区、适用范围 ,以及污染物在呼吸道沉积量的差异 ,认为 ICRP的呼吸道模型可以兼容美国 EPA的呼吸道模型。

In this paper,the respiratory tract models developed by ICRP and USEPA are compared with each other.Through the comparison of the physiological characteristics,arrange of application,as well as the deposition,it is concluded that the ICRP model can compacted with the USEPA model.
