“…In general, the average values of Ra eq for the studied cement samples were lower than the limit value of 370 Bq kg −1 recommended by Organization for Economic Cooperation and Development [32]. The terrestrial environmental radiation sources of indices dealing with the assessment of the excess gamma radiation arising from construction equipment such as outdoor and indoor hazard indices and gamma radiation indices has been investigated by several investigators [33][34][35][36][37][38][39]. For this study, the gamma index (I γ ) was computed using the relation recommended by the European Commission and used by [7,32]…”

This work deals with the measurement of the radioactivity concentrations from different cement samples collected from the South Gondar Zone, Ethiopia. The measurement of naturally occurring radioisotopes and radiation health impact indices caused by these nuclides in cement samples are indisputable in the dwellings. Specifically, the average concentrations for 226Ra, 232Th and 40K were estimated as 76.53, 81.67, and 407 Bq kg−1, respectively. It was seen that all the measured mean values were greater than the world’s limited levels. External and internal hazard indices are calculated as defined by the European Commission from the corresponding concentrations of 226Ra, 232Th and 40K nuclides. Moreover, the natural radionuclides have variety of concentrations which must be caused by the types of raw materials used in the industries for the production of cement.
