摘　　要：目的 了解沈阳市改装场所室内氡污染水平,分析其可能影响因素,为制定针对性防控措施提供科学依据。方法 选择沈阳市2017年建成的734处改装场所,检测其室内氡浓度,分析各种改装因素与氡浓度之间的关系。结果 与住宅(n=581)相比,办公场所室(n=153)内氡浓度较高[(69.285±7.128)vs.(75.822±4.090)Bq/m^(3),P <0.05];室内场所氡浓度最主要影响因素为层高;住宅室内氡浓度影响因素包括墙面使用大白、距主干道距离;办公场所室内氡浓度影响因素有墙面使用大白、使用地板、理石和地胶。结论 应针对室内氡浓度相关影响因素制定科学防控措施,以控制其暴露水平。Objective To examine indoor radon pollution and its associates in houses and offices with recent interior decoration in Shenyang city of Liaoning province and to provide evidence for developing targeted control measures against the pollution. Methods From Shenyang Construction Engineering Quality Testing Center, we collected the data on indoor radon detections for 581 houses and 151 offices after recent interior decoration in 25 buildings in Shenyang city during 2017.The concentrations of radon were described and the relationship between the indoor radon and decoration conditions was analyzed statistically. Results The mean indoor radon concentration of the offices was significantly higher than that of the houses(75.822±4.090 vs. 69.285±7.128 Bq/m^(3), P < 0.05). The most important influencing factor of room-specific radon concentration is the floor number of the room located on. The major influencing factors of indoor radon concentration for houses included whether the white powder(mainly consisted of calcium carbonate, cellulose and white latex) being used for interior wall decoration and the distance from a main road;in addition to whether the white powder being used for interior wall decoration, the indoor radon concentration of an office also influenced by the utilization of floor, marble tile, and polyvinyl chloride floor covering. Conclusion Decoration-related factors need to be concerned for the prevention and control of indoor radon pollution in houses and offices.
