During 2017-2018 academic year, a School­Work Pathway (SWP) project has been developed and accomplished with the collaboration of students attending the last year of the scientific high school of Cerveteri (Rome). The main focus of the project was to introduce students to an environmental problem that is not well known but it is locally present. The project has been addressed to the study of natural radioactivity due to the presence of tuff outcrops (Tufo rosso a scorie nere and Tufi stratificati varicolori di Sacrofano, deriving from middle­lower Pleistocene volcanic activity) that naturally produce the radioactive gas radon. Thus, the Cerveteri area has a natural radioactivity but radon is a gas that can migrate and easily escape in the atmosphere. However, tuffs can be used as building...
