Summary
Electromagnetic radiation is one of the main causes of artworks degradation, especially those made from organic materials such as paper. Its energy induces chemical and photochemical reactions which result in irreversible changes of material properties. On the other hand, thanks to the development of science during 20th cenutry, new ways in which it is used positively were found. Infrared, ultraviolet radiation and x-rays are applied in structural methods for documentation and investigation.Gamma radiation is used for disinfection and disinfestation and visible light and ultraviolet radiation for paper bleaching. These methods are non-destructive if the allowable amount of radiation is used.
