A device that detects the passage of charged particles via the ionization of gas that they cause as they pass through a region Used to detect the particles produced in certain forms of radioactivity
A gas-filled electrical device which detects the presence of radioactivity by counting the formation of ions
A Geiger-Müller 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
A Geiger-Müller detector and measuring instrument It contains a gas-filled tube which discharges electrically when ionising radiation passes through it and a device that records these events
An instrument for detecting and measuring ionizing radiation It contains a gas-filled tube which discharges electrically when ionizing radiation passes through it
