Energy deposition refers to the process by which energy is transferred from radiation to a material, leading to ionization, excitation, or heating of the material. This concept is crucial in fields like medical physics, nuclear engineering, and radiation protection, where understanding the interaction between radiation and matter is essential for applications such as cancer treatment and nuclear reactor design.

Ionization is the process in which an atom or molecule acquires a negative or positive charge by gaining or losing electrons, often in response to energy input. This process is fundamental to various fields such as chemistry, physics, and environmental science, influencing phenomena like conductivity, chemical reactivity, and atmospheric dynamics.

ionization

Excitation refers to the process by which an electron or other particle is raised to a higher energy level within an atom or molecule, often through the absorption of energy. This process is fundamental in various scientific fields, including physics, chemistry, and biology, as it underpins phenomena such as fluorescence, phosphorescence, and the operation of lasers.
