摘　　要：目的通过分析淮安市2015-2016年沉降灰总α、β放射性测量结果,为日常及核应急情况下大气放射性监测提供科学依据。方法依据《江苏省食品中放射性物质监测工作手册》制定采样计划并对沉降灰样总α、总β放射性进行测量分析。结果共检测沉降灰样16份,总α放射性水平为(2.19±0.54)Bq/m^2,总β放射性水平为(8.72±1.83)Bq/m^2。结论建议将沉降灰样品源总α总β计数率和放射性水平结果一起作为大气核放射水平监测指标。Objective Based on the analysis of the gross α and gross β radioactivity measurements of the fallouts in Huaian city from 2015 to 2016 to provide a scientific basis for the daily and nuclear emergency monitoring of atmospheric radioactivity.Methods Sampling plan was made and gross α and gross β radioactivity of the fallouts were tested in accordance with＂Handbook of monitoring of radioactive substances in food in Jiangsu Province＂. Results A total of 16 fallouts were detected,the arithm etic average values for gross α and gross β radioactivity were in the range of（2. 19 ± 0. 54） Bq/m2 and（8. 72 ±1. 83） Bq/m2 respectively. Conclusion It is suggested that the gross α and gross β count rate and the radioactive level of the fallouts should be made as the atmospheric nuclear radiation level monitoring indicators.
