Understanding the controls on uranium (U) mobility in environment is key to improve management of sites contaminated by U mining activities. Previous research has shown that natural or engineered wetlands are particularly able scavenge high amounts U(VI) and U(IV) under noncrystalline forms. However, questions remain respective roles sorption reduction processes removal from running waters wetl...

Nuclear power and modern agriculture are two crucial sectors for sustainable development in the United Arab Emirates (UAE). As these industries mature rapidly country, their long-term inter-compatibility needs monitoring with local data on transfer of radionuclides from arid sandy soils to farm products. Date palms, main crop Arabian Peninsula, remain largely unstudied radioecological impact as...

The Earth's redox evolution has been commonly assumed to have played a key role in shaping the evolutionary history of biosphere. However, whether and how shifts marine conditions are linked biotic events – foremost rise animals ecological expansion eukaryotic algae late Proterozoic oceans remains heavily debated. Our current picture global during this critical interval is incomplete. This part...

This study was conducted to determine the radioactivity concentration in soil samples of Anarak-Khour district located at central Iran. 48 soil samples from a depth of 10-15 cm were taken from seven different sites for monitoring. The radioactivity concentration of 238U, 232Th, 137Cs and 40K in soil samples was determined, using a high resolution (HPGe detector, p-type) γ-spectrometry by detect...

Background: Measurement of the radiation dose distribution is important in assessing the health risk a population and serve as reference in documenting changes to environmental radioactivity in soil due to man-made activities. Materials and Methods: The activity concentration of 238U, 232Th and 40K in soil samples obtained from different locations in Ajaokuta Local Government area was measured ...
