An ionization chamber is a device used to measure ionizing radiation, such as alpha, beta, and gamma rays. It consists of a gas-filled chamber with electrodes that detect charged particles produced when radiation interacts with the gas. When radiation passes through the chamber, it ionizes the gas, creating positive ions and free electrons, which can be collected to produce an electrical signal. These chambers are commonly used in various fields, including radiation protection, medical imaging, and nuclear industry. They provide accurate measurements of radiation levels, helping ensure safety and compliance with regulations. Ionization chambers are essential tools for monitoring and studying radiation exposure.
