The Analysis of 222Rn and 220Rn Natural Radioactivity for Local Hazard Estimation: The Case Study of Cerveteri (Central Italy)

A study of the Etruscan Necropolis of Cerveteri in Central Italy revealed localized moderate radon (222Rn) anomalies (>16,000 Bq/m³) in soils near a funerary site, linked to volcanic tuff outcrops. Indoor radon measurements showed medium-low levels (<200 Bq/m³), except for some dwellings exceeding the EU-recommended threshold (>300 Bq/m³). The research also explored thoron (220Rn) activity in soil gas, providing new insights into radon sources affecting homes despite its shorter half-life. This work highlights the need for awareness and remediation in areas with natural radioactivity, particularly where tuff-based structures are common.
