| Abstract: | This paper describes the results of a radiological survey for the purpose to determine the level Radioactivity concentration in chromite rocks for establishing a basic database of radioactive elements in rocks. Herein, we focus on analyzing radioactivity indices in thirty samples of Chromite rocks have been collected from different locations in Blue Nile State, twenty samples representative Gerri mountain area, and ten samples Gam mountain area respectively. As such, the data provide the basis for a reference map to detect emissions or a significant increase in radiation level in the region. Rocks radioactivity were measured by gamma ray spectrometer using an efficiency NaI (Tl) detector. The comparison between two locations is used by independent t-test. The activity concentrations of three natural radionuclides namely 226Ra, 232Th and 40K has been determined. They results showed that these radionuclides were present in average activity concentration of (6.05±6.22, 6.27±6.7 and 50.97±74.47Bq/kg) respectively, these results were lower than the worldwide levels. The average absorbed dose rate (DR) was 8.8±9.76 nGy.hr-1, the average Annual Effective Dose equivalent (AEDE) was 0.01±0.01mSv. y-1. The Radium Equivalent activity concentration (Raeq) was 19.12±20.8 Bq/kg. Hex 0.08±0.14 and Hin 0.16±0.04 for all rock samples of chromite of both area, these results were does not poses any risks, as evidenced by the values of the external hazard (Hex), absorbed dose rate D(nGy.hr-1, radium equivalent (Raeq), and Annual Effective Dose Equivalent (AEDE) indices (all values were less than recommended levels for worldwide and some countries). However the concentration means of the 40K, 226Ra and 232Th in Garri Mountain has highly significantly (P≤ 0.01) over that of the Gam Mountain. |
