Artifact & Archeological Elemental Analysis

Artifact & Archeological Elemental Analysis

Neutron activation analysis uses a direct measurement on archeological samples to provide a “trace element fingerprint”. This avoids the problems such as incomplete dissolution or the loss of volatile elements that are common to chemical testing techniques.
