Uranium in drinking water from the south coast districts of Kerala, India
Background: The South-west coast of India is known to have very high levels of natural background radiation due to the monazite beach sand. Uranium is the heaviest trace element found in all terrestrial substances at varying levels with chemical and radio toxicities. It supports several short-lived radioisotopes in its decay series including radium. Uranium in drinking water is importa...
متن کاملCooling history and exhumation of the nepheline syenites, NW Iran: constraints from apatite fission track
Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...
متن کاملWhat Is Depleted Uranium
T na m What Is Depleted Uranium? Depleted uranium is created as a byproduct during the processing of natural uranium to make it suitable for use as fuel in nuclear power plants or as a component in nuclear weapons. In natural uranium, 99.27% of the mass consists of atoms of uranium-238. About 0.72% of the mass consists of atoms of uranium-235, and a very small amount (0.0055% by mass) is uraniu...
متن کاملEstimation of Cadmium and Uranium in a stream sediment from Eshtehard region in Iran using an Artificial Neural Network
Considering the importance of Cd and U as pollutants of the environment, this study aims to predict the concentrations of these elements in a stream sediment from the Eshtehard region in Iran by means of a developed artificial neural network (ANN) model. The forward selection (FS) method is used to select the input variables and develop hybrid models by ANN. From 45 input candidates, 13 and 14 ...
متن کاملOverview of Fission Safety for Laser ICF Fission Energy
This paper reviews fission safety design principles and approaches for coupling inertial confinement fusion (ICF) to a subcritical fission blanket, in Laser ICF Fission Energy (LIFE) power plants. LIFE power plants use fuel derived from either spent fuel from fission reactors, or from natural uranium or thorium. By using fusion neutrons, LIFE plants can fission a large fraction of the heavy met...
