e·lec·tron beam

(ĕ-lektron bēm)
Form of radiation used principally in superficial radiotherapy.


any of the negatively charged particles arranged in orbits around the nucleus of an atom and determining all of the atom's physical and chemical properties except mass and radioactivity. Electrons flowing in a conductor constitute an electric current; when ejected from a radioactive substance, they constitute the beta particles.

electron acceptor
see oxidant.
electron beam
the stream of electrons that flows from the anode to the cathode in the x-ray tube and then interacts with the tungsten target to produce x-rays.
electron carrier
a molecule associated with membrane-bound proteins that accepts and transfers electrons.
electron donor
electron micrographs
photographic images of electron microscopic fields.
electron microscope
see electron microscope.
electron microscopy
technology of using an electron microscope.
