Geiger-Muller counter (medicine)


Geiger-Muller counter
<instrument> 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.
