【摘要】 采用美国SUN公司的1027型测氡仪测得我国内蒙、山东、河南、湖北、湖南、广西6省共8个城市地下人防工程内的氡浓度,最高值为547.6 Bq／m3,最低值为22.2 Bq／m3。从地质背景、地下水、通风情况等五个方面讨论了氡浓度的影响因素,并提出主要影响因素为通风情况。更多还原

【Abstract】 In this work, we used a Model 1027 Continuous Radon Monitor from the Sun Nuclear Corporation to measure radon level in air of the underground structures in 8 cities. The max. value of radon concentration in these underground structures is 547. 6 Bq/m3 and the min. value is 22. 2 Bq/m3. The influence to radon under different conditions has been discussed. Ventilation cfficiency is the most important condition.更多还原
