成都地铁环境氡浓度与γ辐射水平调查研究
Investigation and Research on Radon Concentration and Gamma Radiation Level in Chengdu Metro
摘要
Abstract
Purpose:Understand the radon concentration and gamma radiation in the air of Chengdu Metro.Methods:The solid track etching method and the instantaneous measurement method were used to investigate the radon concentration and gamma radiation dose in Chengdu Metro stations,and the measured data were compared and analyzed.Results:The results showed that the measured range of radon concentration in Chengdu Metro was(9.7～32.5)Bq/m3,and the average radon concentration was(18.4±4.3)Bq/m3 which was lower than that in other cities in China.The range of gamma dose rates in Chengdu Metro stations was(74.9～82.6)nSv/h,and the mean value was(78.8±1.0)nSv/h which was lower than the mean value of indoor gamma dose rate in Chengdu area.It was estimated that the effective dose of metro staff caused by radon inhalation and gamma radiation exposure in the metro environment was about 0.30 mSv/a,which was far lower than the standard limit.Conclusion:The investigation showed that radon concentration and gamma radiation in Chengdu Metro did not pose additional radiation hazards to the metro staff.关键词
