| Abstract | ||
| The radioactivity level of cement in some selected samples was determined and discussed .Five cement samples were collected from (Gasseem-Saudia Arabia, Medinaa-Saudi Arabia, Kufa-Iraq, Leon Mark-India, Mogaum Yamamh-Saudi Arabia).The activity concentrations of natural radio nuclides as well as that of the fission product were evaluated by gamma ray spectrometry using scintillation detector (NaI (Tl)).The average of rings concentrations in the surveyed cements samples were (217.44-3725.45) BqKg-1, (31.87-387.33) BqKg-1 and (157.28-3145.6) BqKg-1 for 226Ra, 232Th and 40K, respectively. The activity concentration values of 226Ra, 232Th and 40K in Kufa-Iraq sample would produce minimum annual gonadal dose equivalent of (1187μsy-1), and the maximum value of annual gonadal dose equivalent is (12920μsy-1) was noted in Madinaa Saudi Arabia sample. | ||
