Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis.
Background radiocarbon activity is measured, and the values obtained are deducted from the sample’s radiocarbon dating results.
Accelerator mass spectrometry (AMS) is a modern radiocarbon dating method that is considered to be the more efficient way to measure radiocarbon content of a sample.
In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present.
The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.
