During the recent conflict in Yugoslavia, depleted uranium rounds were employed and were left in the battlefield. Health concern is related to the risk arising from contamination of areas in Kosovo with depleted uranium penetrators and dust. Although chemical toxicity is the most significant health risk related to uranium, radiation exposure has been allegedly related to cancers among veterans ...

Uranium and thorium within the Earth produce a major portion of terrestrial heat along with a measurable flux of electron antineutrinos. These elements are key components in geophysical and geochemical models. Their quantity and distribution drive the dynamics, define the thermal history, and are a consequence of the differentiation of the Earth. Knowledge of uranium and thorium concentrations ...

Using the force-matching method we develop an interatomic potential that allows us to study the structure and properties of α-U, γ-U and liquid uranium. The potential is fitted to the forces, energies and stresses obtained from ab initio calculations. The model gives a good comparison with the experimental and ab initio data for the lattice constants of α-U and γ-U, the elastic constants, the r...

Boltwoodite and uranophane are uranyl silicates common in oxidized zones of uranium ore deposits. An understanding of processes that impact uranium transport in the environment, especially pertaining to the distribution of uranium between solid phases and aqueous solutions, ultimately requires determination of thermodynamic parameters for such crystalline materials. We measured formation enthal...

This paper spotlights on determining the concentrations and distribution of radionuclides in paleozoic lateritic paleosol samples from El-Gor area, southwestern Sinai, Egypt, using high-resolution gamma spectrometry. The concentrations of eU (ppm), eTh (ppm), and K (in percentage) were determined. The obtained data of eU, eTh and their ratios were used for calculations of uranium migration tend...

BACKGROUND The Navajo Nation suffers from a legacy of environmental pollution from historical uranium mining activities, resulting in adverse public health outcomes and continuous exposure. OBJECTIVE Partner with a Navajo graduate student and community members in a field campaign to characterize the spatial distribution and geochemistry of uranium for a multipathway uranium exposure assessmen...

In a survey on uranium and 226Ra concentrations in water distributed by Finnish waterworks, 548 samples were analysed that covered drinking water networks servicing 84% of all consumers. Among all consumers, the mean and median uranium concentrations at the point of use were 0.58 and 0.15 g L–1. The mean uranium concentration in drinking water produced from groundwater was 0.88 g L–1, and when ...

The main goal of this study is to investigate the capability of zeolites A and P synthesized from Iranian natural clinoptilolite for uranium uptak. The removal of uranium(VI) from aqueous solution via ion exchange by zeolites in a single component system with various contact times,  temperatures and initial concentrations of uranium(VI) was investigated. The experimental results we...

background: depleted uranium (du) is uranium with low content of u 235 produced as a result of uranium enrichment. du has high density (19.05 g /cm3), which is 2.54 more than iron, so it’s high penetrating power makes it preferable as emanations with high penetration power. it was used in second gulf ware in 1991 for first time. the radioactivity of soil, plants, fruit, meat, milk and water is ...
