The relatively short operating life and temperature limitations of chemical batteries, another option, constrain their application in space. Radioactive materials offer an alternative power source.

A breakthrough in heavy-element chemistry shatters long-held assumptions about transuranium elements. Researchers have ...

The transplutonium actinides are highly radioactive and rare, making them difficult to study. To examine their chemical ...

But one Australian man had a much riskier hobby—collecting elements from the periodic table, including radioactive ones.

60-inch cyclotron. Enough material has been made for chemical studies by tracer technique in the way in which the properties of element 93 (neptunium ; Np) and 94 (plutonium ; Pu) were first ...

A wildlife corridor plans to connect two Superfund sites at the former Rocky Flats plutonium plant and the Rocky Mountain ...
