| Özet |
| The purpose of this study is to assess potential radiological impacts of utilizing pulverized fly ash (PFA) as a constituent in ordinary Portland cement. For this purpose, the activity concentrations of 226Ra, 232Th, and 40K in samples of PFA and Portland cement containing 15%, 20%, and 25% by mass PFA were measured using gamma-ray spectrometry with HPGe detector. The mean activity concentrations of 226Ra, 232Th, and 40K were found as 366.6, 113.7, and 460.2 Bq kg − 1, 94.2, 25.9, and 215.3 Bq kg − 1, 113.7, 34.3, and 238.3 Bq kg − 1, and 124.2, 41.8, and 279.3 Bq kg − 1 for the examined samples of PFA, Portland cement with 15%, 20%, and 25% by mass PFA, respectively. Radiological parameters such as radium equivalent activity, external exposure index (activity concentration index), internal dose index (alpha index), indoor absorbed gamma dose rate, and the corresponding the annually … |
