The objective of the present study is focused an the assessment of the radiological risk from building materials used in Attica region, Greece. Bricks and concrete com- monly used in Attica region have been studied for both natural radionuclide content and radon exhalation. The high-resolution gamma-ray spectroscopy technique, as well as radon exhalation measurements, have been employed. The technique used for the measurements of the radon exhalation is called "continuous accumulation- counting" method and has been described in detail by the authors in earlier pub- lications. This measurement technique is based on the continuous air flow through a sealed chamber containing the sample and through a scintillation counter (Lucas cell). The counting is continuous as well.
