Explain the basic way that each device detects radioactivity. Match the words in the left column to the appropriate blanks in the sentences on the right. thermoluminescent dosimeter Geiger-Müller counter scintillation counter Reset Help In this instrument, 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 crystals. When the crystals are heated, the electrons relax to their ground state, emitting light. The amount of light emitted is proportional to the radiation exposure. In a , radioactive emissions pass through a material (such as NaI or CsI) that emits ultraviolet or visible light in response to excitation by high-energy photons. The photons excite the atoms to a higher-energy state. The atoms release this energy as light, which is detected and turned into an electrical signal that is read on a meter.
