DURHAM, NC - Much of the naturally occurring radioactivity in fracking wastewater might be removed by blending it with another wastewater from acid mine drainage, according to a Duke University-led st...
A survey of radioactivity content and associated radiological risks was carried out in various soils used for agriculture and building materials in Cameroon by means of a well-calibrated high-purity g...
A study on the detection of probable radionuclides and their activity concentrations in the raw material (phosphate rock), final product (fertilizer) and waste samples collected from all the phosphate...
The activity concentration of natural and fallout radionuclides in the soil at some selected Thanas around the TRIGA Mark-II Research Reactor at Atomic Energy Research Establishment (AERE), Savar, Dha...
Radioactivity of the nuclides 238U, 226Ra, 232Th and 40K was measured in soil by γ-ray spectrometry using HPGe detector. A criterion was set in order to analyse soil samples from plain, semi-hilly and...
Radioactivity measurements were carried out around Maumba and Nguluku villages, two of the proposed sites for titanium mining in the coastal area of Kenya. Samples of surface soils were analyzed using...
Concentrations of natural radionuclides (226Ra and 232Th) in ground and drinking waters of some areas in Upper Egypt were determined by gamma ray spectrometry with a HPGe detector setup, coaxial type ...
A comprehensive study was conducted to determine the radioactivity concentrations of beach sand samples from different sites along the coast of Tripoli, northwest Libya, using high resolution γ-ray sp...
