Abstract

In this work the relation between building materials and Radon indoor pollution is evaluated. The work is part of a larger monitoring in progress in the Calabria Region (Southern Italy).<br />The area under investigation is San Giovanni in Fiore (CS) located in the Sila upland plain. An annual monitoring is carried out in many buildings of Sila area, with reference to their different building materials.<br /> Nuclear tracks detector has been used (SSNTD, Solid State Nuclear Track Detector). Obtained results underline that the buildings realized with the local granite rock have greater indoor radon concentrations.<br />The local granitic rocks, representative of the geologic area, have been analyzed by gamma spectrometry constituted by Canberra system HPGe fixed detector cooled by liquid nitrogen high radio-emission values of standard radionuclides as ²²⁶Ra, ²³²Th and ⁴⁰K.
