广元市地表γ辐射剂量率水平分析
|
摘要
目的通过对广元市地表γ辐射进行监测,掌握广元市地表γ辐射剂量率水平和分布情况,并估算居民暴露剂量,为放射性事故预警及评估提供基础数据。方法按照《环境地表γ辐射剂量率测定规范》和《辐射环境监测技术规范》的要求,使用RJ32-3601型多功能放射性检测仪监测监测点的地表γ辐射剂量率,采用SPSS 17.0软件对数据进行统计分析,均数比较采用t检验和单因素方差分析,组间多重比较采用LSD法。结果广元市地表环境γ辐射剂量率均值为70.2 nGy/h,其所致居民人均年有效剂量当量为0.43 m Sv,均低于我国平均水平。结论广元市地表γ辐射剂量率属于正常地表辐射水平,人居环境不受影响。
Objective To master the levels and distribution of surface gamma radiation dose and estimate residents' exposure dose by monitoring surface gamma radiation in Guangyuan city, to provide the basic data for early warning and the evaluation of radiation accidents. Method According to"Norm for measurement of environmental terrestrial gamma radiation dose" and"Technical criteria for radiation environmental monitoring", RJ32-3601 multifunctional radiation detector were using to monitor the surface gamma radiation dose in monitoring sites,and the data were analyzed by SPSS 17.0. The mean was compared by t test and one-way ANOVA,the multiple comparisons between groups were compared with LSD analysis of variance. Results The mean surface gamma radiation dose rate in Guangyuan was 70.24 nGy/h, and the annual effective dose per capita was 0.43 m Sv, which were both lower than the average of China. Conclusion The surface gamma radiation dose rate in Guangyuan is normal,and the living environment there won't be affected by it.
