摘要:
探讨了环境γ辐射水平的季节性变化趋势和规律,通过余弦模型对连云港田湾核电站2005-2008年度γ辐射连续监测自动站的月均值数据进行分析,并与实际值进行拟合比较,得到拟合曲线与实际曲线吻合,余弦模型能反映出γ辐射水平的季节性变化规律的结果。

Abstract:
Discussed the seasonal trends of the levels and patterns of environmental γ, radiation. The cosine model was used to analyze the monthly average of automatic γ radiation continuous monitoring station from 2005 -2008. Compared with actual values, the fitting curve coincided well with the actual curves. The cosine model can reflect the seasonal variation of radiation levels.
Key words:  cosine model  nuclear power plat  γ radiation levels  seasonal trends
