Anotations

Scope note:

A technique of elemental analysis in which a small area on a surface is bombarded with charged particles (non-electrons, usually protons) to produce fluorescent X-rays specific to an element. The method is used in conservation science, archaeology, and geology to obtain an elemental map which may guide research regarding dating, provenance and authenticity.
