地表γ射线空气吸收剂量率与太阳活动的相关性研究

Study on the Correlation Between Air Absorbedγ-ray Dose-rate on Ground and Solar Activities

通过对比γ射线空气吸收剂量率和太阳活动的情况,本文研究日冕物质抛射、X射线耀斑和质子事件等不同太阳活动类型与空气吸收剂量率等的相关性。结果表明,当太阳有日冕物质抛射时,地表γ射线空气吸收剂量率的日极大值较高,但地表γ射线空气吸收剂量率的极值和均值与太阳活动都无明显直接相关性;太阳活动对地表γ射线空气吸收剂量率的统计影响可以忽略。

By comparing theγ-ray air absorbed dose rate and solar activity,this paper studies the correlation between different types of solar activity such as coronal mass ejection,X-ray flares and proton events and the air absorbed dose rate.The results show that when the sun has a coronal mass ejection,the maximum daily maximum value of the surfaceγ-ray air absorbed dose rate is relatively high,but the extreme value and average value of the surfaceγ-ray air absorbed dose rate have no obvious direct correlation with solar activity.The statistical effect of solar activity on the surfaceγ-ray air absorbed dose rate can be ignored.
