The experiment required 500 milligrams of the rare isotope, ruthenium-96, which was not available anywhere in the world. The ORNL production effort required four months of around-the-clock ...

The team then extracted the 122-neutron isotope using a magnetic device called a separator. All uranium isotopes undergo α-decay, a process whereby an atom loses two protons and two neutrons.

Rare Superheavy Oxygen Isotope Is Detected at Last The long-awaited discovery of oxygen 28 might prompt physicists to revamp theories of how atomic nuclei are structured ...

The atom bomb tests that took place in the 1950s and 60s caused a big surge carbon-14, temporarily doubling the amount of the element in the atmosphere and therefore driving up its concentration ...

The Bruce Power Nuclear Facility in Tiverton, Ont., is set to expand production of medical isotopes by installing a second ...

The longest-living nucleus of a nobelium atom has 259 protons and neutrons and its half-life is about an hour. The aforementioned isotope has ten fewer neutrons and lives for just 44 milliseconds.
