Abstract
We collected 7 samples of Black sand from Rosetta beach (north of Nile Delta, Egypt), we measured the activity concentrations of 238U, 232Th and 40K using (HPGe) detector. Average values of 238U, 232Th and 40K were 102.7± 6.2, 173.7 ± 7.9 and 66.6 ± 3.6 Bq kg−1 for samples respectively, Concentrations ranged between 195 ± 11.5 to 14 ± 0.97 Bq kg−1 for 238U, 366 ± 16 to 15 ± 0.9 Bq kg−1 for 232Th, 83.7 ± 4.1 to 53.5 ± 2.7 Bq kg−1 for 40K The activity of some samples is more than the United Nations Scientific Committee on the Effects of Atomic Radiation UNSCEAR - and the International Atomic Energy Agency IAEA-recommended exemption threshold. Also, we calculated the radiological indices which have values more than recommended limits. So, radiation exposure to Black sand may present a radiological hazard which needs radiation regulations and regular monitoring of black sand sites.
