It is generally accepted that radon emission is strongly influenced by the geological characteristics of the bedrock. However, transport in-soil and entry paths indoors are defined by other factors such as permeability, building and architectural features, ventilation, occupation patterns, etc. The purpose of this paper is to analyze the contribution of each parameter, from natural to man-made, on the radon accumulation indoors and to assess potential patterns, based on 100 case studies in Romania. The study pointed out that the geological foundation can provide a reasonable explanation for the majority of the values recorded in both soil and indoor air. Results also showed that older houses, built with earth-based materials, are highly permeable to soil radon. Energy-efficient houses, on the other hand, have a tendency to disregard the radon potential of the geological foundation, causing a higher predisposition to radon accumulation indoors and decreasing the general indoor air quality.
人们普遍认为，氡的释放强烈受到基岩地质特征的影响。然而，土壤中的迁移和进入室内的途径则由其他因素决定，如渗透率、建筑和建筑特征、通风、居住模式等。本文旨在分析在罗马尼亚的 100 项案例研究的基础上，每种参数（从自然到人为）对室内氡积累的贡献，并评估潜在的模式。研究指出，地质基础可以为土壤和室内空气中记录的大多数数值提供合理的解释。结果还表明，使用土基材料建造的年代久远的房屋对土壤氡具有高度的渗透性。另一方面，节能房屋往往忽视地质基础的氡潜力，导致室内氡积累的倾向更高，并降低了一般室内空气质量。
