Abstract
The radioactivity concentrations of 226 Ra, 232 Th and 40 K in some commercial flooring materials used in Tiruvannamalai, Tamilnadu, India, were measured using NaI(Tl) gamma ray spectrometer. The natural radionuclide contents, Ra equivalent activities and various hazard indices were also calculated to assess the radiation hazard. It was found that none of the results exceed the recommended limit value. All samples under investigation are within the recommended safety limit and do not pose significant radiation hazards. This study can be used as a reference for more extensive studies of the same subject in future.
