摘　　要：目的掌握京唐港口岸常见放射性因子的本底值范围,为今后开展口岸放射性监测工作提供基础信息。方法2014—2015年,在京唐港泊位和锚地定期开展放射性因子监测,记录数据并进行统计分析。结果在95%置信水平上,泊位的放射性均数的置信区间分别是α射线值为0.003~0.004 Bq/cm2、β射线值为0.019~0.070 Bq/cm2、γ射线值为0.03~0.05μSv/h。锚地的放射性均数的置信区间分别是α射线值为0.002~0.004 Bq/cm2、β射线值为0.012~0.051 Bq/cm2、γ射线值为0.02~0.04μSv/h。泊位和锚地的γ射线值差异有统计学意义（P〈0.05）。结论掌握了京唐港口岸泊位与锚地放射性本底值,可以将锚地与靠泊本底值一体化对待,制定适合本口岸的放射性因子异常情况的初步预警机制。Objective To understand the distribution of radioactive factors and reference range of background value at Jingtang port,and to provide basic information for the radiation monitoring. Methods The radioactive background values were monitored regularly and analyzed at berth and anchorage from 2014 to 2015. Results At 95%confidence level,the mean confidence interval of radioactive value of α-ray,β-ray and γ-ray at berth was 0.003~0.004 Bq/cm2,0.019 ~0.070 Bq/cm2,and 0.03 ~0.05 μSv/h,respectively. The mean confidence interval of radioactive value of α-ray,β-ray and γ-ray at anchorage was 0.002 ~0.004 Bq/cm2,0.012 ~0.051 Bq/cm2 and 0.02 ~0.04 μSv/h,respectively. The value of γ-ray monitored at berth and anchorage showed statistical difference（P 0.05）. Conclusion The background value of radioactivity at berth and anchorage of Jingtang port were obtained,and the radioactive background of anchor and berth could be considered as integration for making the preliminary warning mechanism.
