Opis:: The linear attenuation coefficients of different marble samples (Perlato Beige, Regal Beige and Crema Siva Beige) produced in Amasya were measured. The measurements have been performed at the photon energies of 511, 835 and 1274 keV which were obtained using $\text{}^{22}Na$ and $\text{}^{54}Mn$ sources. The measurements have been performed using a gamma spectrometer which contains 3"×3" NaI(Tl) detector connected to 16384 channel Multi-Channel-Analyser (MCA).

Opis:: Radioactive nuclei were created at the beginning of the Universe and with a long half-life, are still present in Earth's crust. The radiations due to the radionuclides contribute to natural background radiation. This generally occurs in ground-source materials (stone, soil, rocks, etc.) in different concentrations. The levels of radiation are due to the uranium, thorium and potassium present in the material. In this study, the natural radioactivity concentrations of coals extracted in Suluova have been determined using a NaI(Tl) γ -ray spectrometer system. The radium equivalent activities of the samples were all below the recommended limit values (370 Bqkg¯¹). The value of external hazard indices is less than unity.
