How Does A Geiger Counter Work?

by

Learning how a geiger counter works is pretty important especially when you are going to buy the best one. By studying its working process, you can realize what the body part of this measuring instrument is highly critical. Thus, when looking for the Geiger counter products on the market, you know what to read more.

Not only for purchase purpose but also for DIY projects. You can design your own model.

Whatever your needs, it’s not a waste of time to learn how a Geiger counter works. This radiation measuring device can save yourlife. Besides, this article only requires less than 5 minutes to read.

So, how does a Geiger counter work?

The name Geiger counter come from the way it works. It employs the Geiger Muller tube as the sensor. The tube is filled with a certain gas commonly Argon.

This gas cannot get out from the tube but the particle from radioactive elements can enter and hit the gas atom. The particle being said is Gamma. While alpha and beta need to enter from the tube window. This window is covered with mica. The mica allows all the particles to enter but it prevents the gas from get outside.

Some products can even prevent the alpha particle or alpha and beta particles from entering the tube. In this scenario, perhaps the mica is doubled behind with aluminum foil (for alpha) and a thicker aluminum plate (for alpha and beta).

How Geiger Counter Works

Electrodes are employed to support in making pulse. While the particles enter the tube and hit the gas atoms, the positive ions are attracted to anode electrode while the negative ions are attracted to katode electrode. The potential voltage happens and generates pulse. Pulse is turned to be sound by electronic circuit.

After learning how a geiger counter works, you may ask how to make its DIY version. Surely, you can. The sensor that you can buy is either SBM-20 or LND-712 or LND-7317.
