background: the presence of radionuclides in the soil, measures need to be taken to minimize the radiation dose to humans. it is mostly gamma-emitting radionuclides that contribute to the radiation dose in long term behavior of these radionuclides in soil may determine the extent to which such countermeasures need to be applied. materials and methods: the activity concentration of these radionu...
In the search for aqueous habitats on Mars direct proof of (ancient) flowing water is still lacking, although remote sensing has provided indications of young fluvial systems. To demonstrate that such proof can be given, we examined surface marks on recent terrestrial sand grains by atomic force microscopy (AFM) and applied a quantitative three-dimensional analysis that can numerically distingu...
Inside the finest fractions of aggregates, usually wasted by ready mix concrete companies, valuable heavy minerals content is substantial. The concentration and recovery contained in dredged fine aggregates waste, located Pyeongtaek South Korea, were investigated to develop a process that can recover concentrate most each mineral. raw material contains ilmenite, magnetite, monazite, zircon. A g...
