Abstract |
|
|
| The assessment of the environmental impact in Abu Zaabal city, Egypt has been studied. Gamma ray spectrometry survey was carried out to this assessment in order to evaluate the radiological hazard of the natural radioactivity. Environmental samples were collected from Abu Zaabal city and the surrounding regions. The radioactivity concentration of 238U series, 232Th series and 40K were measured and analyzed using a hyper pure germanium detector. The analysis of the spectra was done using Gamma Vision analysis software. The specific activity concentrations ranged from ˂ D.L. to 524 Bq/kg for 238U, from ˂ D.L. to 43.9 Bq/kg for 232Th and from ˂ D.L. to 270.88 Bq/kg for 40K. The absorbed dose rate D ranged from 0.003 nGy/h to 235.25 nGy/h, the calculated annual effective dose (E) ranged from ˂ D.L. to 1.44 mSv/y. The external hazard index (Hex) ranged from 0.00002 to 1.47 and internal hazard index (Hin) have been calculated ranged from 0.00002 to 2.89. (Raeq) ranged from 0.0056Bq/kg to 71.22 Bq/kg. The Gamma index (Iγ) ranged from 0.00002 to 1.82.
