Radon (Rn) is the second most common cause of lung cancer after smoking. As radon poses a significant risk to human health, radon-affected areas should be identified to ensure people's awareness of risk and remediation. The primary goal of this research was to investigate the local natural radioactivity (in soils, groundwater, and indoors) because of the presence of tuff outcrops (from middle-lower Pleistocene volcanic activity) that naturally produce radioactive gas radon at Cerveteri (Rome, Central Italy). The results of the radon survey highlighted moderate (>16,000 Bq/m) but localized anomalies in soils in correspondence with a funerary site pertaining to the Etruscan Necropolis of Cerveteri, which extends over a volcanic rock plateau. Indoor radon measurements were performed at several tuff-made dwellings, and the results showed medium-low (<200 Bq/m) values of indoor radon except for some cases exceeding the reference level (>300 Bq/m) recommended by the 2013/59 Euratom Directive. Although no clinical data exist regarding the health effects of thoron (Rn) on humans, the study of Rn average activity concentration in the soil gas survey reveals new insights for the interpretation of radon sources that can affect dwellings, even taking into account the considerable difference in the half-lives of Rn and Rn.
氡（Rn）是仅次于吸烟的第二大肺癌致病因素。由于氡对人体健康构成重大威胁，应确定氡影响区域，以确保人们了解风险并采取补救措施。本研究的主要目的是调查由于凝灰岩露头（来自中更新世火山活动）的存在而导致的当地自然放射性（土壤、地下水和室内），这些露头自然产生放射性气体氡，地点在意大利中部罗马的切尔韦特里（Cerveteri）。氡调查的结果突出显示了土壤中存在中等偏高（>16,000 Bq/m）但局部异常的情况，这些异常与切尔韦特里（Cerveteri）的伊特鲁里亚墓地的一个丧葬地点相对应，该墓地位于火山岩高原上。在一些凝灰岩建造的住宅中进行了室内氡测量，结果显示室内氡的中低水平（<200 Bq/m），除了一些超过 2013/59 年 Euratom 指令建议的参考水平（>300 Bq/m）的情况。虽然没有关于氡（Rn）对人体健康影响的临床数据，但土壤气体调查中 Rn 平均活度浓度的研究为解释可能影响住宅的氡源提供了新的见解，即使考虑到 Rn 和 Rn 的半衰期存在相当大的差异。
