Pronunciation: gi'ger mul'er
Definition: an instrument for measuring radioactivity by counting the emission of radioactive particles; it consists of a metallic cylinder, negatively charged, in a tube containing a fine, positively charged wire at its center; radiations produce ionization of the gas molecules between the cylinder and the wire and result in an electrical discharge independent of the energy of the impinging particle or ray.
