摘要

目的探讨地热田高氡住宅氡的来源及控制措施;方法冬季和夏季采用ATD检测仪测定室内和土壤氡浓度;用伽马射线能谱法测定了建筑材料中的放射性核素;采用6150 A - D/6H X-γ射线探测仪测定建筑材料放射性核素剂量率;并对其中一栋房屋进行了氡还原技术;结果32个房间平均氡浓度分别为(106.4±63.7)Bq/m 3(夏季)和(421.3±138.2)Bq/m 3(冬季),12.5%(夏季)和96.9%(冬季)房间氡浓度超过150 Bq/m 3。建筑物周围土壤氡平均浓度为12 890 Bq/m 3 (n = 24),是北京市典型土壤氡浓度(7 600 Bq/m 3)的1.7倍,土壤减压后房屋氡浓度可降至100 Bq/m 3以下。主动减压和被动减压的氡降低率分别为94.6%和71.4%。结论土壤减压对降低底层室内氡浓度效果明显。地热田居住环境中的氡应引起重视。摘要: 目的 探讨地热田高氡房屋氡的来源与治理。 ■■■■■■■■■■■■■■■■■■■■■采用γ能谱法测量房屋主体建材放射性核素含量;采用6150 D / 6 h X -γ剂量率仪测量房屋主体建材的外照射剂量率;对其中一栋房屋实施土壤减压技术的降氡改造。结果夏冬季32个房间氡浓度均值分别为(106.4±63.7)Bq /米3和(421.3±138.2)Bq /米3,分别有12.5%和96.9%的房间超过150 Bq /米3。建筑物周围土壤氡浓度均值为12890 Bq / 3(检测点n = 24),是北京市土壤氡浓度典型值(7 600 Bq /米3)的1.7倍。实施土壤减压改造后冬夏季房屋中氡浓度均可降至< 100 Bq /米3,主动减压法降氡率为94.6%,被动减压法降氡率为71.4%。结论 土壤减压法对降低底 层房间氡浓度效果明显, 地热田居住环境中氡的问题应引起关注。

The average radon concentration in soil around buildings was 12 890 Bq/m 3 ( n = 24), which is 1.7 times of the typical soil radon concentration in Beijing (7 600 Bq/m 3). After soil decompression, the radon concentration in the house could be reduced to less than 100 Bq/m 3. The radon reduction rates of active decompression and passive decompression were 94.6% and 71.4%, respectively.
