Nuclear energy
Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts. The component parts are neutrons and protons, which are collectively called nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and neutrons.

Nuclear energy
Radiography
Energy; Nuclear energy
The use of sealed sources of ionising radiation for nondestructive examination of the structure of materials. When the radiation penetrates the material, it produces a shadow image by blackening a ...
Radioactivity
Energy; Nuclear energy
The property possessed by some elements (such as uranium) of spontaneously emitting energy in the form of radiation as a result of the decay (or disintegration) of an unstable atom. Radioactivity is ...
Radioactive decay
Energy; Nuclear energy
The spontaneous transformation of one radioisotope into one or more different isotopes (known as "decay products" or "daughter products"), accompanied by a decrease in radioactivity (compared to the ...
Radioactive waste
Energy; Nuclear energy
Radioactive materials at the end of their useful life or in a product that is no longer useful and requires proper disposal.
Radioactive series
Energy; Nuclear energy
A succession of nuclides, each of which transforms by radioactive disintegration into the next until a stable nuclide results. The first member is called the parent, the intermediate members are ...
Radioactive contamination
Energy; Nuclear energy
Undesirable radioactive material (with a potentially harmful effect) that is either airborne or deposited in (or on the surface of) structures, objects, soil, water, or living organisms (people, ...
Radiation warning symbol
Energy; Nuclear energy
An officially prescribed magenta or black trefoil on a yellow background, which must be displayed where certain quantities of radioactive materials are present or where certain doses of radiation ...
