Radiation detectors are devices used to identify and measure radiation levels in the environment. They can detect different types of radiation, such as alpha, beta, and gamma rays, which are emitted by radioactive materials. Common examples of radiation detectors include Geiger counters and scintillation detectors, which help ensure safety in places like hospitals, nuclear power plants, and research laboratories. These detectors play a crucial role in protecting public health and the environment. By monitoring radiation levels, they help prevent exposure to harmful radiation from sources like nuclear accidents or medical treatments. Understanding how these devices work is essential for maintaining safety in various industries.
