detonation of an atomic bomb? I believe it is gamma radiation.
Fallout emits large amounts of gamma.
It is neutrons.

Mostly Uranium 235, Uranium 238, and Plutonium 239 Also fission fragments. If your talking about any kind of radiation then it would be thermal radiation from the heat blast. When you split the Uranium atom you get 2 Neutrons, 2 protons + 2 fission fragments. 1 of the 2 neutrons will be uranium 235 and the other plutonium 239. the radiation from a nuclear blast will at first be heat. This will be continious until the energy that created it is depleated. Note Uranium 238 is weaker than Uranium 235 and it absorbs neutrons. Uranium 235 has a far greater Neutron density (99.3%) Uranium 238 = (0.7%)
Polonium, which has an atomic number of 84, decays to astatine, which has an atomic number of 85, a negative beta particle is emitted.
Protactinium-231 emit alpha particles, gamma radiations, X-rays.
Other than visible light used to scan the original to be copied, some heat, and the kind of very low and extremely low frequency electromagnetic radiation emitted by all electrical devices, photocopiers do not emit radiation.
The lunar radiation
On any level the movement of charge carriers (electrons, protons etc) cause EM radiation to be emitted. Gamma rays are also emitted as the result of some radioactive decay reactions All radioactive decay reactions produce EM radiation of some kind because they involve the movement of charge carriers such as the ejection of alpha particles (double positive charge).
Light is emitted when an electron jumps from a higher energy orbit to a lower energy one. The wavelength (=colour) depends on the energy difference. Bigger is bluer, smaller redder.

The spectrum is a kind of analysis of the light emitted by a star.
