Describing the strong nuclear force.

A war fought using nuclear (fission and/or fusion) weapons.

The branch of physics that studies the nucleus of the atom, its internal structure and components.

A predicted drop in global temperature following a nuclear war due to dust in the upper atmosphere reducing sunlight reaching the ground.

The age in which nuclear energy and nuclear weapons were developed.

(physics) The unit of magnetic moment used to describe nucleons such as the proton.

the explosion of a nuclear weapon at such an altitude that the fireball remains above the ground

A proposed aircraft that would be powered by nuclear energy.

(physics) The distribution of the intensity of particles or radiation emitted in a nuclear process as a function of energy - a unique signature of each process.
