However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.

Radiocarbon dating is especially good for determining the age of sites occupied within the last 26,000 years or so (but has the potential for sites over 50,000), can be used on carbon-based materials (organic or inorganic), and can be accurate to within ±30-50 years.

After koranic, followed by primary and secondary French-school studies in Senegal, Cheikh Anta DIOP will be endowed with a double higher training in Human Sciences and in Natural Sciences in Paris, France.

Working partnership were then established between IFAN and CEA/CNRS (French National Center for Scientific Research) with the vital collaboration of Jean Le Run (who implemented the first whole radiocarbon dating system at the CNRS Gif-sur-Yvette, in France), Jacques Labeyrie, Director of the CFR (Centre des Failbles Radioactivités or Center for Weak Radioactivity) at Gif-sur-Yvette and Georgette Delibrias, Director of the radiocarbon laboratory of the CFR.

A quantity discount of 10% will be applied to submissions of 10 or more samples.

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.

The Shroud of Turin , which many people believe was used to wrap Christ's body, bears detailed front and back images of a man who appears to have suffered whipping and crucifixion.

It was first displayed at Lirey in France in the 1350s and subsequently passed into the hands of the Dukes of Savoy.

By a notification on April 17, 1963, Theodore Monod formalizes the existence of the radiocarbon dating laboratory (within the Department of Archeology and Prehistory of IFAN)and nominated Cheikh Anta DIOP at its head.

In 1966, the laboratory became fully functional with the installation of the complete "RA14" radioactivity measurement setup from Intertechnique, thanks to the Atomic Energy Commission (CEA) from Saclay, in France.

As Controls, three samples whose ages had been determined independently were also dated.

The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.

After returning to Senegal, he was appointed at IFAN (French Institute of Black Africa initially, and Fundamental Institute of Black Africa a few years later), which was then managed by Theodore Monod.
