摘要

为了研究深圳市环境辐射水平及其变化趋势，在2011-2020年间对深圳市开展了环境地表γ剂量率、空气中氡浓度、水中总α、总β水平及土壤中天然放射性含量的监测工作。结果表明：2011-2020年深圳市环境地表γ剂量率水平为69.3~131.0 nGy/h，空气中氡浓度为6.23~18.60 Bq/m,3,，水中总α水平为0.016~0.225 Bq/L，总β水平为0.028~0.826 Bq/L，土壤中天然放射性含量均处于本底水平范围。深圳市环境辐射水平在本底范围内波动，建议增加海洋放射性监测项目，进一步完善深圳市放射水平基础数据。

Abstract

This study was conducted to assess the levels and trends of environmental radiation in Shenzhen between 2011 and 2020. The monitoring encompassed dose rate, radon concentration in the air, water radioactivity, and natural radioactivity content in soil. Results indicated that the dose rate ranged from 69.3 to 131.0 nGy/h, while radon concentration was between 6.23 and 18.60 Bq/m,3,. The activity concentration in water, for total alpha and total beta, ranged from 0.016 to 0.225 Bq/L and 0.028 to 0.826 Bq/L, respectively. The natural radioactivity content in soil was found to be within background levels. Overall, the environmental radiation levels in Shenzhen fluctuated within the background range. To enhance the comprehensiveness of the data, it is recommended that marine radiation monitoring projects be increased and the basic data on radiation levels in Shenzhen be further refined.
