O. Hahn and F. Strassmann 1 have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they ...

Cesium-137 is formed as a fission product by operating a nuclear reactor. Cesium-137, also known as Cs-137, was first released into the atmosphere during Oppenheimer’s Trinity test on July 16 ...

A controlled nuclear fission reaction releases one million times more energy per kg than a chemical reaction such as burning coal, oil or gas. This means much less fuel is required than for a ...

Fermi's task, however, was to create a controlled nuclear reaction; that is, to split the atom without creating a deadly explosion. Theoretically, it was possible. During fission, a fast-moving ...
