Messenger Radiocarbon dating has transformed our understanding of the past 50, years. Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts. Radiocarbon dating works by comparing the three different isotopes of carbon.

Fluorine is a chemical element with symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.. Among the elements, fluorine ranks 24th in universal abundance and 13th in terrestrial.

Distinction between Relative and Absolute Dating: In the early stage of prehistoric studies, dating of any event or site was obtained tentatively. A particular event or specimen is dated in relation to other event or some reference point. By relative methods one can know whether a particular culture is younger or older than another one, and thereby arrange a series of things in a sequential time frame.

These methods were basically depending upon stratigraphic position of the site or kind of remains associated with the site. However, these methods have never been able to provide a date in terms of years, nor it can calculate the total time span involved in each cultural period. The relative chronology, in the words of Wheeler , is ” It provides the actual time spanned by a site sequence with close approximation. These methods can provide chronological sequence of even geographically isolated events or culture.

Thus, the rate of change differential development in separate areas, and the identification of the geographic sources of widespread cultural influences can be established with the help of different absolute dating. Absolute dating or chronometric dating usually demands high technology, laboratory and hence costly.
