How does a Geiger counter distinguish between radiation and cell phone radiation?

Recently, Japan released the nuclear radiation detector with fire, and some people questioned how the Geiger counter, the core equipment of the nuclear radiation detector, can distinguish between nuclear radiation and cell phone radiation. Will it affect the detection next to computers,tds meter cell phones and other electronic products?

How does the Geiger counter detect radiation?

To understand how the Geiger counter distinguishes between nuclear and cell phone radiation, it is first important to understand that they belong to different types of radiation. Radiation is usually divided into ionizing and non-ionizing radiation. Ultraviolet and infrared rays, which are common in life,dosimeter vs geiger counter as well as radiation from cell phones, are often said to belong to non-ionizing radiation, which is generally harmless to the human body.

Nuclear radiation, on the other hand, contains ionizing radiation such as alpha particles, beta particles, gamma rays, neutrons, etc. Ionizing radiation destroys the atomic economic structure of the social substance, causing it to develop into a free-trade electron or an ion, and these ionizing radiations have the ability to have a certain high level of energy, which can cause serious harm to the human body's tissues and organs by penetrating the substance.

Geiger counters have become a classic tool for measuring nuclear radiation because they are used to detect ionizing radiation such as alpha particles, beta particles and gamma rays. Therefore, when actually using a Geiger counter, you are naturally not exposed to non-ionizing radiation such as cell phone radiation or infrared radiation.

So, how does a Geiger counter detect ionizing radiation and alarm?

The geiger counter radiation detector is based on the ionizing properties of rays on gases. Its detectors (called "Geiger tubes") are usually made by filling the ends of a metal tube with a thin layer of gas, then installing a wire electrode along the axis of the tube, and applying a voltage between the wall of the tube and the wire electrode that is slightly lower than the breakdown voltage of the gas inside the tube.

In this way, under normal conditions, the gas inside the tube is not discharged. When high-speed particles are injected into the tube, the energy of the particles ionizes and conducts the gas inside the tube, and a rapid gas discharge phenomenon occurs between the filament and the wall of the tube, resulting in the output of a pulse current signal.
