摘要: 为了解深圳市氡浓度水平,2025年3月到10月测量了深圳市151个点位的土壤氡浓度、土壤氡析出率及原位大气氡浓度,得到土壤氡浓度范围为 3.72×103~3.44×104 Bq/m3,土壤原位大气氡浓度范围为 5.60~19.46 Bq/m3。深圳市土壤氡浓度具有明显的季节变化特征,旱季土壤氡浓度较高,而雨季土壤氡浓度较低;室外大气氡浓度季节性差异不明显,大气氡浓度与土壤氡浓度无显著相关性,与土壤氡析出率没有关联。深圳市土壤及室外大气氡浓度在正常本底范围,与国内外其它地区无明显差异。

Abstract: This study comprehensively investigates the radon concentration levels in soil and ambient air in Shenzhen, providing scientific basis for radiation environmental impact assessment. From March to October 2025, soil radon concentration, soil radon exhalation rate, and ambient air radon concentration were measured at 151 sites in Shenzhen. Soil radon concentrations in Shenzhen range from 3.72×103 to 3.44×104 Bq·m-3. In-situ ambient air radon concentrations range from 5.60 to 19.46 Bq·m-3.The soil radon concentration in Shenzhen exhibited a clear seasonal variation, with higher concentrations in the dry season and lower concentrations in the rainy season. Soil moisture content is the key factor determining the radon exhalation rate, which subsequently affects the soil radon concentration levels. The seasonal variation of outdoor air radon concentration in Shenzhen was not significant. Ambient air radon concentration showed a weak correlation with soil radon concentration, while no correlation was observed with soil radon exhalation rate. The levels of soil and outdoor air radon in Shenzhen are within the normal background range and show no significant difference from other regions in China or abroad.

Key words: soil radon concentration, air radon concentration, soil radon exhalation rate, Shenzhen
