摘要：

The natural radioactivity levels and some radiological parameters of Turkish Portland cements (PC) originated in various regions were determined in this study. The activity concentration of cement samples for Ra-226, Th-232, and K-40 were measured using a gamma-ray spectrometer with high purity germanium radiation detector. The PC samples had activity concentrations of 33.0, 16.7, and 239.5 Bq kg(-1) for Ra-226, Th-232, and K-40, respectively. The mean value of radium equivalent value (Ra-eq) was found to be 75.4 Bq kg(-1). The radium equivalent values in the cement samples were lower than the acceptable level of 370 Bq kg(-1). The calculated radiological parameters were found to be below the acceptance levels.
