摘要: Building materials can expose public and workers to radiation because of their content radium, thorium potassium isotopes. This is why it very important from the radiological point view survey natural radioactivity commonly used building in any country. work consists measurement (226)Ra, (232)Th (40)K activity concentrations a variety Tunisia on estimation hazard. The maximum value radium equivalent for studied was equal 169 Bq kg(-1) corresponds clay brick, which lower than recommended 370 kg(-1). In this work, several indexes were calculated found be under highest permitted limit.
