An ionisation area, or ionisation region, refers to a volume of space where the presence of ions is significant or intentionally created. This can occur naturally or through artificial means. In natural phenomena, ionisation areas are often associated with high-energy events. For example, the Earth's ionosphere is a region of the upper atmosphere that is ionised by solar and cosmic radiation. This ionisation plays a crucial role in radio wave propagation. Lightning strikes also create temporary, intensely ionised channels within the atmosphere.

Artificially created ionisation areas are found in various technological applications. Particle accelerators generate high-energy beams that ionise gases, enabling the study of fundamental physics. Plasma torches create extremely hot, ionised gases used for cutting, welding, and material processing. In medical imaging, ionisation chambers are used to measure radiation doses, essentially detecting the ionisation caused by X-rays or gamma rays. Ionisation areas are fundamental to understanding and manipulating charged particles in both natural and engineered systems. The properties of an ionisation area depend heavily on the density of ions, the type of ions present, and the presence of neutral particles and electromagnetic fields.
