Radioactivity and health risk assessments in cement samples commonly used as construction materials in the case of South Gondar Zone, Ethiopia

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