A Radhound Geiger counter measuring radiation emitted by a tree in Chernobyl. Geiger counters are widely used to detect gamma radiation and X-rays collectively known as photons, and for this the windowless tube is used. However, detection efficiency is low compared to alpha and beta particles.
Online shopping for Geiger Counters, Radiation Detectors & Radiation Protection from a great selection of Industrial & Scientific products at everyday low prices.
Geiger counters start at less than $100 and can go up to $400 or $500 for high-end consumer devices. Under $150, you’ll find lower-end devices with limited ranges, features, and other capabilities.
Geiger worked with Rutherford to develop a radiation-measuring device — a counter to detect the alpha particle, a combination of two protons and two neutrons that's given off by an atom during radioactive decay.
A Geiger counter is a device that can detect radioactive radiation. It works by passing radioactive elements through an inert gas inside the machine, which ionizes the gas. The resulting ions can be easily detected relative to radioactivity itself.
Learn how Geiger counters work in-depth. Discover the science behind detecting ionizing radiation, the types, uses, and limitations of Geiger counters.
A Geiger counter has two main parts—a sealed tube, or chamber, filled with gas, and an information display. Radiation enters the tube and when it collides with the gas, it pushes an electron away from the gas atom and creates an ion pair.
Supplier of Geiger counters for the detection of radioactivity, offering a selection of handheld and external probe models of radiation detectors, and guidance on how to select the right model of Geiger counter for your application.
The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation.
The Geiger counter, a pivotal device in radiation detection, was invented by Hans Geiger in 1908 and later refined by Walther Müller. This comprehensive guide explores its history, operating principles, types, applications, and contemporary advancements.
