instrument for measuring the intensity of radiation.
An instrument used to detect, measure and record nuclear emanations, cosmic rays and artificially produced subatomic particles.
An instrument, consisting of a gas-filled tube containing electrodes between which an electric voltage is maintained, used to detect ionizing radiation. When radiation passes through the tube, short pulses of current are generated, which are measured and related to the intensity of the radiation.
An instrument used to measure the radioactivity that emanates from certain minerals by means of a Geiger-Mueller tube.
Subject: Resources & Reserves An ionization chamber with its vacuum and its applied potential so adjusted that a gamma ray or other ionizing particle passing through it causes a momentary current to flow. The surge of current can be amplified and counted so as to measure the intensity of radioactivity in the vicinity of the chamber. http://xmlwords.infomine.com/xmlwords.htm?term=Geiger+Counter++[ Pics List

A device used to indicate the presence of radioactive minerals.
Instrument that measures radiation output.
A device used to measure the amount of radioactivity present. Half-Life: The amount of time needed for half of the atoms in a quantity of radioisotope to decay. Ion: Atom, molecule, or molecular fragment carrying a positive or negative electrical charge. Ion Exchange: The process in which an ion in solution takes the place of another ion in a natural or man-made material. Ionization: The production of ions from neutral atoms or molecules by some process. For example, exposure to ionizing radiation. Isotope: Atoms of the same element that have equal numbers of protons but differing numbers of neutrons. MilliRem: A unit of radiation exposure equal to one-thousandth of a rem.
a radiation detection and measuring instrument consisting of a gas-filled tube containing electrodes, between which an electrical voltage but no current flows. When ionizing radiation passes through the tube, a short, intense pulse of current passes from the negative electrode to the positive electrode and is measured or counted. The number of pulses per second measures the intensity of the radiation field. Geiger counters are the most commonly used portable radiation detection instruments.
A Geiger-Müller detector and measuring instrument. It contains a gas-filled tube which discharges electrically when ionizing radiation passes through it and a device that records the events.
Instrument that measures intensity of radiation. It is very useful for detecting radioactive minerals.
A radiation detector consisting of two electrodes with a low-pressure gas in between. A voltage is maintains such that if radiation passing through the counter ionizes the gas, an avalanche of electrons will occur. Geiger counters can count radiation but cannot distinguish either the energy or kind of radiation.
Device used to detect nuclear particles.
The most commonly used portable radiation detection and measuring instrument, consisting of a gas-filled tube containing electrodes, between which an electrical voltage but no current flows. When ionizing radiation passes through the tube, a short, intense pulse of current passes from the negative electrode to the positive electrode and is measured or counted. The number of pulses per second measures the intensity of the radiation field. Geiger counters are highly sensitive to beta particles but relatively insensitive to gamma rays and x-rays.
an instrument for the detection and measurement of ionizing radiation
A Geiger counter, also called a Geiger-MÃ¼ller counter, is a type of particle detector that measures ionizing radiation.
