What is the Geiger counter being used for?
A Geiger counter (Geiger-Muller tube) is a device used for the detection and measurement of all types of radiation: alpha, beta and gamma radiation. Basically it consists of a pair of electrodes surrounded by a gas. The electrodes have a high voltage across them.
What is the process of radiation protection in Geiger counter?
The Geiger–Müller tube is filled with an inert gas such as helium, neon, or argon at low pressure, to which a high voltage is applied. The tube briefly conducts electrical charge when a particle or photon of incident radiation makes the gas conductive by ionization.
Are Geiger counters dangerous?
Unfortunately, regular Geiger counters have a serious drawback. High levels of radiation often saturate the tube, resulting in a false-low reading and serious health hazards among all involved.
What happens when a Geiger-Muller counter absorbs radiation?
The Geiger-Muller tube detects radiation. Each time it absorbs radiation, it transmits an electrical pulse to a counting machine. This makes a clicking sound or displays the count rate. The greater the frequency of clicks, or the higher the count rate, the more radiation the Geiger-Muller tube is absorbing.
What is the meaning of Geiger?
: an instrument for detecting the presence and intensity of radiations (such as cosmic rays or particles from a radioactive substance) by means of their ionizing effect on an enclosed gas which results in a pulse that is amplified and fed to a device giving a visible or audible indication.
Is a Geiger counter a dosimeter?
Geiger counters measure low levels of radiation, such as looking for surface contamination. Dosimeters can be in the form of a sticker, badge, pen/tube type, or even a digital readout. They all measure the total accumulated amount of radiation to which you were exposed.
Is there a Geiger counter app?
Turn your Android device’s camera into a Geiger counter with DARPA-funded app. Image Insight on Monday announced the first free trial release of GammaPix for Android smartphones, an application that loosely measures gamma radiation with the phone’s camera. You simply pull up the app, and begin taking a reading.

How do you use a Geiger Muller counter?
Turn on the Geiger counter to apply an electrical charge to the anode wire. The counter will click or flash about 10 to 20 times per minute as it detects background radiation. Pass the sensor, called a Geiger-Mueller tube, over the material to be evaluated with the thin mica window facing the material.

Geiger counter/Inventors
The German physicist Hans Wilhelm Geiger is best known as the inventor of the Geiger counter to measure radiation. In 1908, Geiger introduced the first successful detector of individual alpha particles. Later versions of this counter were able to count beta particles and other ionizing radiation.
