, particles emitted by radioactive nuclei pass through an argon-filled
chamber. The energetic particles create a trail of ionized argon atoms. High voltage applied between
a wire within the chamber and the chamber itself causes these newly formed ions to produce an
electrical signal that can be displayed on a meter or turned into an audible click. Each click
corresponds to a radioactive particle passing through the argon gas chamber.
contains crystals of salts such as calcium fluoride that are excited by the ionizing
radiation. The excited electrons are trapped by impurities that are intentionally introduced into the
