摘　　要：甘肃河西典型地区(祁连山、龙首山)既是自然保护区,又是铀镭含量较高的区域,因此环境中天然辐射水平较高,很有必要对这些地区在不同地质背景下进行全面的室内氡水平调查评价。采用FYCDY-P30测氡仪测量并分析了氡浓度水平与分布,再结合地质背景等条件研究其对氡浓度释放规律的影响。研究结果表明:花岗岩地质条件外围居室内氡浓度高于其他岩性背景下的居室内氡浓度;建筑年代、材质等也是影响居室内氡浓度水平的因素。调查不同地质背景条件下的氡浓度释放规律对氡测评与采取降氡措施有重要指导意义。The typical areas of Hexi,Gansu(Qilian Mountains,Longshou Mountains)are not only natural protected areas,but also areas with high uranium and radium content,resulting in higher levels of natural radiation in the environment.Therefore,it is necessary to carry out a comprehensive investigation and evaluation of indoor radon levels in these areas under different geological backgrounds.The FYCDY-P30 radon detector is used to measure and analyze the levels and distribution patterns of indoor radon concentration,and the impact of geological background conditions on radon concentration release is studied.The results show that the indoor radon concentration levels in peripheral areas where granite geological conditions exist are higher than those in other rock-type backgrounds,and factors such as building age,materials,etc.are also found to impact indoor radon concentration levels.Investigating the radon release laws under different geological background conditions has important guiding significance for radon assessment and taking measures to reduce radon.
