X-ray fluorescence

Definition

X-ray fluorescence (XRF) is an analytical technique used to determine the elemental composition of materials by measuring the fluorescent X-rays emitted from a sample when it is excited by a primary X-ray source. This non-destructive method has become increasingly important in archaeology, especially for analyzing artifacts and materials in Greek archaeology, as it allows for detailed elemental analysis without damaging the items being studied.

5 Must Know Facts For Your Next Test

1. XRF can analyze a wide range of materials, including metals, ceramics, and glass, making it particularly useful in archaeological studies.
2. The technique provides rapid results, allowing researchers to quickly assess the elemental composition of artifacts in situ or during conservation efforts.
3. One of the key advantages of XRF is its portability; handheld devices allow for field analysis, enabling studies at excavation sites without the need for laboratory facilities.
4. XRF can help identify provenance, or the origin of materials, which is crucial for understanding trade routes and cultural interactions in ancient Greek society.
5. The data obtained from XRF can also inform restoration efforts by helping conservators understand the original materials and techniques used in artifact creation.
