摘　　要：介绍了美国核管会用于核与辐射事故后果分析的辐射评价系统(RASCAL)的主要功能和特性,重点分析了RASCAL的源项计算剂量模块、场外监测数据计算剂量模块、气象数据处理模块,以及源项计算模式、大气输运扩散模式和剂量计算模式。最后,将RASCAL应用于我国某核电厂事故应急演习中,评价分析事故情景下的放射性影响,并将其结果通过Google Earth进行三维展示。The development history,main function and basic principle used for emergency response of RASCAL,which is used for analyzing nuclear and radiate accident by American Nuclear Regulatory Commission,are presented in the study. The main modules / models are analyzed selectively,including source term to dose,field measurement to dose,meteorological data processor,source term calculation,transport,diffusion,and dose calculations. Then,RASCAL is applied to assess the radiological consequence of a nuclear power plant accident emergency exercise. The assessment conclusion is displayed through Google Earth as 3D style.
