摘　　要：随着进出口贸易量的日益增长,大宗资源类商品在口岸通关的速度尤为重要,进出口货物的放射性现场快速检测分析方法的研发迫在眉睫。本研究基于无源效率刻度方法,在已建立的放射性现场快速检测技术基础上,分析了空气中测量和铅室中测量等不同情形下的方法对常见的天然放射性核素和人工放射性核素的探测限,为口岸大宗资源类商品的放射性现场快速检测提供了技术支撑。As the increasing trade volume and requirement of fasting customs clearance,the research on radiation rapid determination method at port for bulk resource commodities is imminent.Based on the sourceless efficiency calibration method,the detection limit of radiation rapid determination method for common natural radionuclides and artificial radionuclides under different conditions such as the air and the lead chamber were analyzed in this study.The new method was established to provide technology support for international trade emergencies,and to promote the construction of nuclear security and counter-terrorism capacity at port.
