摘　　要：通过双滤膜法对沈阳某校园学生教室、宿舍、实验室、演播厅等4个场所的氡浓度值进行了测量并计算。结果表明:学生宿舍和学生教室内,氡浓度水平均低于国家氡浓度限值(200Bq/m^3),而学生实验室和演播厅内的氡浓度水平普遍偏高。保守估计(学生每日8小时均在实验室,四季辐射水平相同),实验室氡浓度测量值将超过国家的剂量限值,会对学生的身体健康带来不利影响。因此,针对实验室氡浓度的检测与处理措施,提出了若干有效建议。Tw o-filter method was presented on the measurement and calculation of the radon concentration in four places of Shenyang campus including the student classrooms,dormitories,laboratories and studios. The results showed that the radon concentration in the student dormitories and classrooms were below the national radon concentration limits 200 Bq / m^3,while the student laboratory and studio radon concentration levels were on the contrary. The radon concentration in laboratory will exceed the national dose limits and adversely affect student health according to the most conservative estimate（ the same student stays in the lab 8 hours in a day and the radiation level is same in the four seasons）. In this regard,the long-term detection of the radon concentration in the laboratory and the use of sealing treatment,or anti radon paint to paint the wall etc. were put forw ard.
