| 摘 要： | 目的 评估放射性工作人员的吸入铀所致内照射剂量。方法 采取ICRP提出的放射性核素内照射剂量系数方法,结合ICRP66、78号报告提供的生物动力学模型,针对铀的体内代谢规律建立相应的数学计算模型,并用MATLAB软件编程计算了吸入情况下肺中铀和生物样品中铀的预期值。结果 计算结果与ICRP78号报告中数据基本吻合。结论 建立的数学计算模型可方便准确地估算吸入情况下铀的内照射剂量。

| Abstract: | Objective To evaluate workers' internal dose of uranium.Methods The dose coefficient method of ICRP is adopted in this paper.According to the Biokinetic Model about the radionuclide described in ICRP66、78 and metabolizing rules of uranium in body, mathematical and analytic mode is built.The program built by MATLAB calculates the uranium contents of lung and biologic samples under circumstances of inhalation.Results The result is consistent with the data in ICRP 78.Conclusion The method model can be used easily and exactly to evaluate internal dose of uranium. |
