New superheavy isotope reveals complex relationship between quantum effects and fission
In a study published in Physical Review Letters, scientists at GSI Helmholtzzentrum für Schwerionenforschung have discovered a new superheavy isotope, 257 Sg (seaborgium), whose properties are ...
Scientists cheered another indication that the Atomic Age was starting to roll. After long delay and soul-searching, the Manhattan District this week agreed to supply qualified customers with about ...
Antarctica's ice sheets are still releasing radioactive chlorine from marine nuclear weapons tests in the 1950s, a new study finds. This suggests regions in Antarctica store and vent the radioactive ...
A new study has unraveled the mystery behind the lingering radioactivity in wild boars inhabiting the Chernobyl exclusion zone, even decades after the catastrophic 1986 nuclear accident. In a recent ...
One year ago last week the Clinton Laboratories at Oak Ridge, Tenn. began selling radioactive isotopes made in its uranium pile. Already, these atomic by-products have had important influences on U.S.
