What Is a Geiger Counter and How Does It Work?
Geiger counter is mainly and specifically use to detect radioactive emissions which includes beta particles and also gamma rays. Therefore, this Geiger counter is composed of a tube and it is filled with some inert gas version.
Furthermore, when that inert gas is reacted by a high energy and high-speed particle, then the inert gas becomes and turns out to be conductive of electricity.
As soon the Geiger counter is exposed to some sort of ionizing radiation, then the particles penetrate completely into the tube and eventually make a collision with the gas.
This process then automatically releases more electrons. Moreover, positive ions start to exit from the tube. And all the negatively charged electrons get attracted to that high voltage middle wire.
Electric current is then created when electrons reach a threshold level. Lastly, to detect more of the radiations, the counter has to be restored to its original and actual state.
What is the Difference Between a Dosimeter and a Geiger Counter?
Geiger Counters measures an exposure rate or you can say the intensity of radiation at a specific and particular location. They mainly and commonly make use of a Geiger tube rather than making use of an ion chamber.
Most importantly, they measure and estimate low levels of radiation. It is in the radioactivity detection field that Geiger counters play an important role.
On the other hand, the dosimeter is a device which is used and availed to measure an absorbed dose kind of ionizing radiation. They usually come and manufactured in the form of a sticker, badge.
Geiger Counter also come in pen/tube type versions or even in a digital readout model format. They measure and generally estimate the accumulated amount of radiation in totality.
Is Geiger Counter Dangerous?
As Geiger Counters are used to detect potentially harmful kind of radiations, that is why one has to remain cautious and careful while using this device. It is in alpha, beta and gamma form that these radiations appear!
Most noteworthy, alpha particles are usually slow. And beta particles can only travel a bit further. It is just these gamma radiations which are harmful and risky of all.
It is the dangerous version of ionizing radiation. And it can even penetrate into your body. For the reason, professionals who use Geiger counters, they must keep themselves safe and sound while encountering and exposing themselves with these harmful radiations.
Most of the time, workers experience a high dose of radiations at the nuclear accident sites and thus experience radiation sickness.
How Much do Geiger Counters Cost?
The cost of Geiger counters varies and differ a lot from one brand to another. You may buy this device in between the price range of a few hundred dollars to xxx dollars. Professionals prefer to use digital Geiger counters as they give more accurate results.
Such digital counters manage to obtain and extract an exact count of detected radioactive particles. The cost of a Geiger counter also depends on what purpose you are using it! As an example, Geiger counters use to check and detect the radiation danger in any kind of emergency situations, such devices are usually expensive.
Besides, counters used to detect environmental levels and scales of radioactivity, their price varies and differ as well. Lastly, quality, guarantee aspect, ease of usage, accuracy aspect differs the price range of Geiger counters at the same time.
