Geiger Counter Principle

The full name of the Geiger tube is the Geiger-Miller tube (G-M tube), which was invented in 1908 and improved in 1928. Since then, the design of the Geiger tube has been largely unimproved. Nuclear radiation includes three types of radiation: alpha particle streams, beta particle streams, tds meter and gamma rays, and the Geiger tube can detect one or more of these, depending on the specific model.

1, Geiger counter, mainly by a hollow structure of metal as well as cylindrical c and a metal conductor w is composed of, w and c electrically insulated and parallel to its axis. c is equipped with a low pressure of about 50 torr of argon (about 1/15 atmospheric pressure), plus the appropriate amount of potential difference to c and w between, making w in a higher potential than c, but still not enough to make through the argon gas as a discharge. At this time the enterprise if there is a particle or some other rays by a very thin window a into, will make the teaching cylindrical cylinder in the argon gas conditions of ionization, the free electronic information will be positively charged wire w attracted.

As the electron accelerates toward w, it collides with other argon atoms and ejects more electrons, which in turn causes more electrons to flow toward w, producing a very short pulse of current, and with the proper amplifier G, dosimeter vs geiger counter these pulses of current can either produce a familiar echo or drive a counter to count the number of particles that have entered C. The counter will be used to count the number of particles that have entered the cylinder.

Function of the Geiger Counter

The purpose of the Geiger counter is to detect and study changes in the background and radiation counts from the surface of the Earth to detect M-class and X-class solar X-ray flares. The background counts of the different radiations are induced by cosmic rays and by the radioactive materials of the Earth's crust, the cosmic rays are coming from the deep space of China and from solar flares on the Sun,geiger counter radiation detector and in order for us to measure and analyze the background information for this enterprise project we need to analyze the background information of the Earth's outer shell of the Earth every hour with the Geiger counter. Geiger counter detection technology background information radiation counting information then made the social background environment radiation counting and derived M-class and X-class solar X-ray flare chart.

Geiger counter circuit for radiation detection

The high voltage generator (IC1, IC2, Q1, T1 and related parts) supplies current to the G-M tube.The pulse generated by the GM tube passes through Q2 and IC1 to reach the pulse generator IC3, which drives the loudspeaker to sound.
