【摘要】 目的探讨如何有效进行物品放射性超标事件的应急处置。方法对2010年04月11日烟台空港查获一起旅客携带燃油添加剂进行放射性监测。结果样品表面0.1m处周围剂量当量率为3.42μSv/h,232Th比活度为26535.7Bq/kg,超过限量的26。5倍[1]。结论应加强对航空口岸核与辐射监测工作,完善应急处置机制。更多还原

【Abstract】 Objective To explore effective measures of responding to excessive radiation emergency.Methods Carry out radiation monitoring of fuel additives carried by passengers intercepted at Yantai airport on April 11th,2010.Results Dose equivalent rate about 0.1m above sample surface is 3.42μSv/h,and the specific activity of 232Th is 26535.7 Bq/kg,which is 26.5 times above limits.Conclusion Nuclear and radiation surveillance should be strengthened at airport and emergency response mechanism should be improved.更多还原
