Uranium Radiation Properties
In natural uranium contained in an undisturbed uranium ore deposit, these decay chains generally are in secular equilibrium. This means that in 1 g of natural uranium (almost) each nuclide of the U238 series has an activity of 12,356 Bq and each nuclide of the U235 series an activity of 568 Bq. In the various processing steps of nuclear fuel production, the equilibrium .
