the main geological units exposed in the lagoa real uranium district have been the subject of geochronological studies using multichronometric approaches (u–pb, pb–pb, rb–sr, sm–nd and k–ar methods) in order to constrain the timing of granite emplacement, metamorphism, hydrothermal alteration and uranium mineralization (turpin et al., 1988, cordani et al., 1992).,facts, pictures, stories about the element radium in the,uranium is radioactive too, but radium is much, much more intensely radioactive, so even tiny amounts in an ore can greatly increase its overall radioactivity. for a time radium was fashionable in luminous watches and quack medical products (which were very harmful unless they were cheap rip-offs that didn't contain any real radium, in which case they were at least harmless).
isotopic fingerprinting of ore deposits. uranium has received a great deal of attention from government officials and scientists worldwide, largely due to the fissile properties of the 235 u nucleus. by far, the largest portion of uranium research has been dedicated to energy production, either in the form of nuclear reactors or nuclear weapons, with the acquisition of u from ore deposits being a primary step.,eur-lex - 32016r1375 - en - eur-lex,plants for the separation of isotopes of natural uranium, depleted uranium or special fissionable material and equipment, other than analytical instruments, especially designed or prepared therefor. 0b001.a. plant specially designed for separating isotopes of “natural uranium”, “depleted uranium”, or “special fissile materials”, as
the relationship between the recorded count rate, ntc (counts/s), and the concentration of k, u, and thorium in the ground is given by ntc = skck + sucu + sthcth where sk, su, sth are the sensitivities of the tc instruments (counts/s per unit concentration of relevant radionuclide), and ck, cu, and cth are radioelement concentrations.,metaschoepite dissolution in sediment column systems,metaschoepite is commonly found in u-contaminated environments and metaschoepite-bearing wastes may be managed via shallow or deep disposal. understanding metaschoepite dissolution and tracking the fate of any liberated u is thus important. here, discrete horizons of metaschoepite (uo3·nh2o) particles were emplaced in flowing sediment/groundwater columns representative of the uk sellafield
