摘　　要：目的了解西安市室内氡浓度水平。方法采用Model 1027连续测氡仪对西安市三环内室内氡浓度水平进行监测。室内氡浓度监测共选取西安市三环内样本数92个,每个采样点选取2-3个监测点,并且对监测点连续监测1 h,所有监测点的平均值即为该点的氡浓度水平。结果西安市三环内室内氡浓度范围为3.70-525.40 Bq/m^3,算术平均值为89.93 Bq/m^3。冬季室内氡浓度水平高于春季。结论除网吧外,西安室内空气氡浓度在国家规定范围之内,网吧室内氡浓度普遍偏高。Objective To get the understanding of the status of indoor radon concentration levels in Xi＇an.Methods Indoor radon concentration in Xi＇an was monitored with continuous radon monitor Model 1027.92 samples are selected in this research.In each sampling places,2 - 3 points were chosen for 1 h continuous monitoring.The sample of indoor radon concentration level is on the average level at all points.Results Indoor radon concentrations within the range of Xi＇an 3rd ring RD from 3.70 to 525.40 Bq / m^3 with an arithmetic average of 89.93 Bq / m^3,and in winter indoor radon concentration level is higher than that in spring.Conclusion The indoor radon concentrations of Xi＇an are within the range of the national standard except for the cybercafe.
