摘要
为获得厦门市的土壤氡浓度水平及其分布规律,使用FD-3017型RaA测氡仪,于2009年5月4日—5月12日对厦门市土壤氡浓度进行布点测量,对实测的100个数据进行统计分析并绘制土壤氡浓度等值线图。结果表明,厦门市土壤氡浓度范围为450～40 800 Bq/m3,平均值为7 538 Bq/m3;同安区的土壤氡浓度水平较高;不同类型土壤中氡浓度不同,粉质黏土土质和干硬性地表形态测量的土壤氡浓度较高。
To ascertain the soil radon concentration level and distribution in Xiamen,during May 4 to 12 in 2009 a survey of spatial distribution of radon concentration in soil was carried out using FD 3017RaD radon monitor in Xiamen.Then the 100 sampling sites were analyzed and the contour map of soil radon concentration in Xiamen was curved.The results indicated that the data set spans from 450—40 800 Bq/m3 and the average is 7 538 Bq/m3.The radon concentration in soil is higher in Tongan district.The soil radon concentration varies with different types of soil and is higher in clay.The radon concentration in soil is also higher when the surface of soil is hard and dry.
