Radioactive californium-252 is a prolific neutron emitter, making it useful for examining jet engine parts for defects, finding underground oil and gas reservoirs, bombarding certain tumors, and ...

This week, we meet the element, californium. I'll give you three guesses as to where this element's name comes from -- and your first two guesses don't count! Californium is a radioactive actinoid ...

This element is one of many first made at UC Berkeley in the 1950s. Unlike most manufactured elements, though, this one is actually useful. This is how it starts up nuclear reactions. Researchers ...

Storing radioactive waste poses a problem for nuclear power facilities worldwide and often leads to heated debates over the pitfalls of nuclear energy production. Pictured, environmental activists ...

The Department of Energy's Oak Ridge National Laboratory - home of one of only two reactor facilities in the world capable of producing californium-252 (Cf-252) - has begun implementing a new six-year ...
