'''Radiation detectors''' provide a signal that is converted to an electric current. The device is designed so that the current provided is proportional to the characteristics of the incident radiation.

The '''electronic band structure''' (or simply '''band structure''') of a solid describes those ranges of energy, called ''energy bands'', that an electron within the solid may have ("allowed bands"), and ranges of energy called band gaps ("forbidden bands"), which it may not have.

The main components of background noise in neutron detection are high-energy photons, which aren't easily eliminated by physical barriers.

'''Noise''' is a random fluctuation in an electrical signal, a characteristic of all [[w:electronics|electronic]] [[w:electrical circuit|circuits]].<ref name="noise">{{cite book
