dictionary help| Geiger-Muller tube --> Geiger-Muller counter | medical dictionary |
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 centre; 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.
