Geiger counter is a device used to detect and measure ionizing radiation. It operates by detecting the emission of radioactive particles or radiation and producing an audible clicking sound or visual display to indicate its presence and intensity.
When a Geiger counter is exposed to ionizing radiation, such as alpha, beta, or gamma particles, it detects the radiation and registers it as a count. The clicks or other indicators become more frequent and intense as the radiation levels increase. Geiger counters are commonly used in various fields, including radiation monitoring, nuclear power plants, medical facilities, and environmental research, to ensure safety and measure radiation levels.
By providing real-time measurements, Geiger counters help assess potential radiation hazards, identify contaminated areas, and monitor radiation exposure for safety purposes.
