Radiation Chemistry
When nuclear reactions occur, energy is released in several forms:
electromagnetic energy is emitted in the form of gamma-rays, x-rays,
ultraviolet radiation and visible light; energy is also released as energetic
(translationally fast or internally excited) nuclei, electrons and
other subatomic particles, and energetic atoms. All of these photons and
particles may react further with their surroundings and induce subsequent
chemistry. The field of radiation chemistry seeks to define how this excess
energy is absorbed and the course of reactions thereby induced. It is
closely related to other fields such as photochemistry, which considers the
consequences of absorption of ultraviolet, visible, and infrared radiation;
radiobiology, which is concerned with absorption of ionizing radiation by
living systems, and radiochemistry, in which chemical reactions are probed
using detection of reactant and product concentrations with radioactively
labeled compounds.
