Effect of Some Physical Properties of the Black Sands on the Radiation Exposures at Mastarouh, North Nile Delta, Egypt

Abstract: The average apparent density of studied sediment is 1599kg/m 3 and its effective porosity is 0.22. The total heavy mineral contents in the black sands at Mastarouh area was found to vary from 10.56 % to 39.66% with an average of 26.60%. Its variation affects the activity concentrations of the four radio-nuclides, 238 U, 232 Th, 226 Ra, and 40 K, as well as the absorbed dose rate, radon flux and the total radioactivity. The mentioned variables display the same behavior like the total heavy minerals except 232 T… Show more

“…These concentrations are higher than the worldwide average of both 238 U and 232 Th which were reported to be 32 and 40 Bq/kg respectively. Some studies concerning the radioactive emanation of these sands and its impact on the inhabitant through air were done on Abu Khashaba beach where the main heavy mineral concentrations as well as the physical dressing pilot plant of the beach sands were studied (Barakat, 2008, Nasr, 2012, Abdel-Razek et. al., 2014.…”
