| 中文摘要 |
| 使用CR-39探测器和探杯型氡监测器,对本所办公楼地下室及办公室内外氡浓度进行2-6个月春夏秋冬不同季节的累积测定。对收集后的CR-39随机扫描读数方式对结果的影响做了比较。结果表明地下室氡浓度高于其他层,室内高于室外,除个别情况外,随机扫描的影响在统计涨落范围内。 |
| 英文摘要 |
| Both indoor and outdoor 222Rn concentrations of an office building in Zhongguancun, Beijing,were determined by using a CR-39 detector and passive integrating radon monitor in different seasons of spring, summer, autumn and winter,with a total sampling time of 2—6 months.The results show that the radon level found in the basement was higher than that in the office rooms above the basement and the indoor radon levels were higher than the outdoor radon levels. The error sources, including the effects of CR-39 random scanning and reading ways on the results of determination, were also discussed. It was found that, except in some individual cases, the extent of influence caused by different scanning ways was within the range of statistical variation. |
