The concentrations of U in natural waters are usually low, being typically less than 4 μg/L in
river water, around 3.3 μg/L in open seawater, and usually less than 5 μg/L in groundwater …

Dissolved uranium in groundwater at high concentrations is an emerging global threat to
human and ecological health due to its radioactivity and chemical toxicity. Uranium can …

Keeping in view the toxicity of uranium and to reduce exposure to uranium and avoid high
doses, it is essential to examine on routine bases the concentration of natural radionuclide …

Wet climatic episodes are known to have prevailed in the Egyptian Sahara several times
during the late Quaternary, most recently during the Holocene 8000 yr ago. Earlier wet …

The Brazilian northeast is known to have sedimentary areas that contain minerals with
anomalous concentrations of naturally occurring radioactive material (NORM). This …

The distribution of uranium isotopes (238 U and 234 U) in groundwaters of the south-
western margin of the Great Artesian Basin (GAB), Australia, and underlying Arckaringa …

Data on the recent migratory history of radionuclides as well as geochemical circumstances
can be obtained from the disequilibrium of the uranium series, which is often brought on by …

Traditional methods for determining uranium in groundwater are spectroscopic methods that
require time, money, and experienced chemists. A prediction method for predicting uranium …

Abstract The" Green Sahara" pluvial phases that alternated with North African hyper-aridity
during the Pleistocene are well recognized in tropical and Mediterranean marine records …

This work is part of a research project that aims to develop a method for combined
radiocarbon and uranium-isotope dating of groundwater. The specific objective of this study …
