The Geiger–Müller counter is a device capable of detecting and counting the charged particles that pass through it. As seen in Figure 1, the Geiger counter is made up of a sturdy metal tube (cathode), hermetically closed at the ends. It contains rarefied gas at a reduced pressure of approximately 0.1 atmospheres. A mixture of argon and ...

What is the point of Geiger counter calibration?
12k 2 22 58. Add a comment. 0. The point of a geiger counter calibration is for confirming the correct detector response and linearity at high and low counts rates. At much higher count rates, the dead time of your detector circuitry comes into effect and the result has to be compensated for counts that are missed.

Geiger Counter Buyer's Guide
Geiger Counters are instruments that can detect and measure radioactivity using a Geiger Mueller tube. Geiger Mueller tubes are commonly referred to as a GM tube tube. The original design of the g-m tube by Hans Geiger and E.W. Mueller in 1928 hasn't changed much and the tube's sensor function remains the same.

In addition to the answer by dmckee, your question about how much radiation a Geiger counter can detect thru 3 brick walls should really be stated as how much radiation can penetrate 3 brick walls. This depends on the energy and intensity of the radiation. The Geiger counter will be sensitive to this radiation.
