First, a dilute acid is used to remove the carbonate fraction of the bone, which accounts for about 75% of its entire mass.

Studies have shown this material is unreliable for radiocarbon dating.

Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.

The lab is based in Miami, Florida, and is the world leader in carbon-14 analyses since 1979.

The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.

It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.

I’ve taken the theory of Carbon Dating – that science reaches further with a little comedy – and applied it to live programming with a new 501(c)(3) called SCIENCE RIOT, INC.

Dating the Amesbury Archer was an important part of the overall archaeological research programme.

Then, the collagen fraction is isolated and purified using filters.

The application of Accelerator Mass Spectrometry (AMS) for radiocarbon dating in the late 1970s was also a major achievement.

Compared to conventional radiocarbon techniques such as Libby's solid carbon counting, the gas counting method popular in the mid-1950s, or liquid scintillation (LS) counting, AMS permitted the dating of much smaller sized samples with even greater precision.

Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials.

In contrast to relative dating techniques whereby artifacts were simply designated as "older" or "younger" than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.

Before drilling the exterior of the bone is carefully cleaned and then about 500 milligrams is drilled.

The bone powder is pretreated and cleaned over about 4 days.
