Abstract
Despite their simple basic principle, gas ionization detectors are still used frequently for the detection of ionizing radiation emitted from both radioactive substances and artificial radiation sources. On passing through a gas, ionizing radiation creates positive ions and electrons. If an electric field is applied, the positive ions start to migrate to the electrode of the opposite charge, where they are collected. By the detection of this electric charge using a suitable electric circuit, an indication of the presence of ionizing radiation is given. Gas ionization detectors can be categorized into three large groups, namely ion chambers, proportional counters, and Geiger-Müller counters. These detector types show different characteristics and detection principles, which are presented and discussed in this chapter. Furthermore, current detector developments and special detector types are reviewed. Possible applications of gas ionization detectors in environmental and life sciences, particle and nuclear physics, dosimetry and health physics, and many more are discussed on the basis of selected examples.
