Preliminary Spectrometric Analysis Measurements of the Sant‘Agata De’ Goti Tuff in the Framework of the National Radon Action Plan

Exposure to indoor radon gas in the living environment, alongside its importance in the Italian national radiation protection legislation, is important to Italy's recently introduced National Radon Action Plan, which aims to comprehensively address radon-related concerns. However, a significant contribution is also made by external exposure due to gamma radiation from building materials. The radiometric characterization of Sant'Agata de' Goti village, in the Campania region, south of Italy, served as a representative case study for implementing radiological risk assessment. Due to the geomorphological characteristics of the location and the unique nature of the volcanic tuff used as a building material it is important to know radiological impact safeguarding historical buildings and cultural heritage. The results obtained by gamma spectrometry on grey tuff samples confirm the presence of high levels of radionuclides' activity related to radon. Considering these findings, it is recommended to increase radiological characterization and dose assessment activities in the area to improve risk management and radiation protection measures. By taking such actions, the safety of residents and visitors can be ensured while preserving the invaluable cultural heritage of Sant' Agata de' Goti for future generations.
