近年来,氡及其子体对环境和人体健康的影响受到了日益增加的关注。本文论述了空气中氡的迁移机理及氡浓度受温度、相对湿度、气压的影响,并利用RAD7型氡测量仪于2004年3月至2005年10月在成都市某开放性室内对空气中氡浓度进行了连续测量,得到了947个氡浓度数据。结果表明,该室内空气中氡浓度的变化规律与气压、相对湿度成正相关,与温度成负相关。
For the purpose of environment protection and people's health, the study of radon and its daughters is of great scientific interest in recent years, this presentation discusses the transport mechanism of radon in the air as well as the effects of temperature, relative humidity and pressure on radon concentration. By using RAD7, a long term of and continuous measurement of radon concentration in an open room in Chengdu were carried out, finally, 947 data were obtained. According to the resuhs, a positive correlation between radon concentration and pressure, relative humidity, and a negative correlation between temperature were appeared.
