Archaeologists also use non-invasive techniques to survey sites known as remote sensing.
An aspect of a site that is only horizontal, such as a road, is not a feature.
There are essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.
The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.
After archaeologists have thoroughly surveyed the site they begin excavation. Then archaeologists excavate the site using trowels, shovels, and various other tools.
They start by setting up a grid and connecting the grid to a datum. They carefully remove dirt and note the precise location of any artifacts found.
There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).
