Abstract

Abstract The second most important source of indoor radon, after soil beneath dwelling, is building material. With the increase in environmental awareness and new energy-saving policies, residents tend to replace the existing windows with tighter windows, which leads to a decrease in air exchange rate and consequently an increase in indoor radon concentration. In case of low exchange rates, dose caused by inhalation of radon and its progeny can exceed external dose originating from the radium content in the surrounding building material. In this paper, surface exhalation rates of radon (222Rn) and thoron (220Rn) from typical building materials used for construction and interior decoration of houses in Serbia were investigated. Surface exhalation rate measurements were performed using the closed-chamber method, while concentrations of radon and thoron in the chamber were continuously measured using an active device, RTM1688-2, produced by SARAD® GmbH. Finally, the impact of the replacement of windows on the indoor radon concentration was estimated.

塞尔维亚使用的建筑材料的氡和钍排放率测量

室内氡的第二大来源是建筑材料，仅次于住宅下面的土壤。随着环保意识的增强和新的节能政策，居民倾向于用更紧的窗户取代现有的窗户，这导致空气交换率降低，从而导致室内氡浓度增加。在低交换率的情况下，吸入氡及其子体所引起的剂量可能超过由周围建筑材料中镭含量引起的外部剂量。本文调查了塞尔维亚用于建筑和室内装饰的典型建筑材料中氡(222Rn)和钍(220Rn)的表面呼出率。表面呼出率测量采用封闭室法进行，而氡和钍的浓度连续测量使用有源装置，RTM1688-2，由SARAD®GmbH生产。最后，估计了更换窗户对室内氡浓度的影响。
