| 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.

| Geiger counter |
A Geiger-M?ler detector and measuring instrument. It consists of a gas-filled tube that discharges electrically when ionizing radiation passes through it and a device that records the events.

| Geiger counter |
A device used to count high energy radiation and particles, such as radioactivity. The counter consists of a Geiger tube or ionization chamber (which converts the incoming radiation into electronic pulses) and associated circuitry which amplifies and counts the pulses.

| Geiger c. |
a radiation counter that uses a gas-filled tube to indicate the presence of ionizing particles; the type and energy of a particle cannot be determined because the degree of ionization produced is independent of them. It is highly sensitive to β particles, but relatively insensitive to γ and x-rays.
