基于ICRP呼吸道新模型的胸区各库滞留函数的计算

Calculation of Thoracic Retention Functions Based on ICRP New Respiratory Tract Model

摘要: 本文基于国际放射防护委员会（ICRP）第66号出版物颁布的工作人员呼吸道新模型，采用分别解一阶线性齐次和非齐次微分方程的方法，得出了胸区各库的滞留函数的表达式，并计算出了不同摄入时间下的肺部的滞留量。计算结果与中国辐射防护研究院编制的INDO2003剂量估算软件的计算结果、ICRP第78号出版物中给出的数据一致性较好，表明胸区滞留函数的计算方法是可靠的。

Abstract: Based on the new respiratory tract model of ICRP publication 66, the thoracic retention functions were gained by solving first order linear and nonlinear differential equations. The result was compared with the data from ICRP publication 78 and the calculation result of INDO2003 software written by China Institute for Radiation Protection. It is shown that the calculation method is credible.
