摘　　要：为保证核动力厂应急控制中心在发生放射性大量释放事故时的可居留性,为其设计和安装了应急通风过滤系统,碘吸附器是该通风系统的主要碘过滤装置。碘吸附器的工作原理决定了其吸附效率受工作环境的温度、相对湿度、进风碘浓度等因素影响。针对某核动力厂应急控制中心设计特征,研究了在RG1.183DBALOCA和S3事故源项下,碘吸附器的吸附效率与室内工作人员接受的有效剂量、甲状腺当量剂量的对应关系,进行了线性拟合,给出了拟合系数,可用于事故后果快速剂量估算。In order to management center In ensure the habitability of the accidents with massive nuclear power plant emergency radioactive material release, the emergency ventilation filter system is always designed and installed. The iodine filter is an important radio-iodine removal device in the ventilation system. The principle of the iodine filter determines that the adsorption efficiency is varied with the temperature and relative humidity of working environment, iodine concentration of air intake and other factors. Using the design feature of an emergency management center built in a nuclear power plant, correspondin relationship between the g to RG1. 183 DBALOCA and $3 accident source term, the adsorption efficiency of iodine filter and the effective dose,thyroid equivalent dose of the staff working in the emergency management center is studied, and the coefficients of linear fitting are given, which can be used for quick estimation of nuclear accident consequence.
