What kind of measurement does an ionization chamber primarily perform?

An ionization chamber primarily performs radiation detection by measuring ionizing radiation. When radiation passes through the chamber, it ionizes the gas inside, producing charged particles (ions). The chamber is designed to collect these ions using electrodes, and the resulting electrical current is proportional to the amount of radiation present.

This method allows for the detection and quantification of various types of radiation, including alpha particles, beta particles, and gamma rays, making ionization chambers valuable tools in fields such as nuclear physics, radiation safety, and medical applications. Their sensitivity and reliability in detecting low levels of radiation are key advantages that underscore their importance in radiation measurement.
