A small amount of vapours of a substance having low ionization potential, called as quenching gas, eg alcohol vapours, is added to gm tube, which discharges at cathode before the principle gas +ve ions which discharges at cathode in about 10^-4 seconds. So the quenching gas neutralizes itself and also the tube....

Quenching in a Geiger-Muller tube refers to the process of stopping or reducing the electrical pulse produced by the tube after it detects radiation. This is typically achieved using a quenching gas that absorbs the excess energy from the ionizing radiation, ensuring that the tube can accurately measure radiation levels without being overwhelmed by a continuous stream of pulses.

Who invented the the device for counting radiation?
The Geiger-Muller counter was invented by Hans Geiger and Walther Muller in 1928.
What is a radioactive device that causes a speaker to click when a charged particle passes through it?
This device is called a Geiger Counter, or sometimes a Geiger-Muller counter, which measures alpha particle concentration. It was developed by Hans Geiger and Walther Muller in the early 1900's.
Instrument for detecting radioactivity?
A Geiger counter is a commonly used instrument for detecting radioactivity. It measures ionizing radiation by detecting the ionization produced in the air by radioactive particles or rays. The device produces an audible clicking sound or visual display to indicate the presence of radiation.
Name the instrument used to detect radioactivity?
A Geiger-Muller counter is the instrument used to detect radioactivity by measuring ionizing radiation levels.
What is the difference between Geiger Muller counter and scintillation?
A Geiger-Muller counter detects ionizing radiation through gas ionization, while a scintillation counter detects radiation through luminescence produced in a crystal. Geiger-Muller counters are more commonly used for detecting alpha, beta, and gamma radiation, while scintillation counters are often used for gamma and X-ray detection due to their higher sensitivity and energy resolution.
What is quenching in G M counter?
stopping the ionization cascade modern geiger-muller tubes use a halogen gas for quenching
What is chemical quenching?
Chemical quenching refers to a process where a reactive species in a chemical reaction is neutralized or deactivated by the addition of a quencher molecule. This effectively stops the progression of the reaction by removing the reactive species. Chemical quenching is commonly used in various chemical and biological applications to control reaction rates or prevent unwanted side reactions.
What are some medical uses of radiation?
to detect radiation, a device such as Geiger- Muller tube is used

Principle of counting technigue geiger muller counter?
what is the principle of geiger muller counter
Why is alcohol vapor used in a Geiger counter?
it is used for quenching of the geiger-counter
Does the geiger muller tube become radioactive?
no. as with anything in a contaminated area its surfacemay become contaminated, but this can and should be washed off.
What are the applications of Geiger Muller scintillation counter to cytological studies?
geiger muller scintilation counter it is application in cytological studies
What is pulse current?
pulse of current is produced at every burst of radiation ending geiger muller tube. when this radiation hits the argon atoms; present in the tube electrons are knocked off.
In what year was the Greiger conter invented?
Geiger counter was devised by Geiger and Rutherford and later in 1928 it was improved by Geiger and Muller.
What is Geiger Muller scintillation?
Simply put, the Geiger-Müller (GM) detector or tube is the "business end" of a Geiger counter. It's the tube that the ionizing radiation "goes into" where it interacts with the gas inside to allow detection of the "count" or "pulse" of ionizing radiation.
