Descripció:
U-238 is the principal isotope of natural U in a mixture (~99.3% abundance) and is the parent nuclide in the mass number (4n+2) decay series of radionuclides (uranium series), the longest known series. Since its discovery by Joly in 1908, radioactive disequilibrium in the U-decay series has been extensively studied in almost all superficial environments. As a consequence, several models have been developed and applied to Environmental Geology studies. This talk will illustrate some study cases held in Brazil with such purpose, as well further applications involving dose measurements in drinking water.
