实验小棚氡浓度测量分析

Measurement and Analysis of Radon Concentration in Small Shed

为验证封闭大棚内空气饱和氡浓度与土壤氡浓度的关系,在已知大棚内空气氡浓度和小棚内空气氡浓度换算关系的情况下,模拟了农作物小棚种植环境;通过实验证明了在棚外钻孔通风的方法可以有效降低棚内氡浓度,为减少农业种植过程中的氡影响提供了实验依据。

In order to verify the relationship between the concentration of air saturated radon in the closed greenhouse and the concentration of radon in soil,due to the limitation of experimental conditions,the cropping environment was simulated under the condition that the concentration of air radon in the greenhouse and the concentration of air radon in the small shed were converted.The experiment proves that the method of drilling and venting outside the shed can effectively reduce the concentration of radon in the shed,and provides an experimental basis for reducing the impact of radon in the agricultural planting process.
