Ultimately, radiocarbon dating accuracy for calculating Iron Age dates, and consequentially Bible chronology has varied from researcher to researcher.
When it comes to Bible chronology the difference between a “high” and “low” chronology is a matter of mere decades not centuries. Other opinions place the transition somewhere between the two—in about 950 B. The date is important because the date you choose will determine whether David and Solomon reigned in the archaeologically poor and archaeologically poorly documented Iron I or in the comparatively rich and richly documented Iron IIa.
Radiocarbon dating uses the naturally occurring isotope Carbon-14 to approximate the age of organic materials. Often, archaeologists use graves and plant remains to date sites.
Since its conception by Willard Libby in 1949, it has been invaluable to the discipline.
It was while working in the Kent Laboratory building in the 1940s that researchers developed radiocarbon dating—an innovative method to measure the age of organic materials.For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.Because it reacts identically to C-12 and C-13, C-14 becomes attached to complex organic molecules through photosynthesis in plants and becomes part of their molecular makeup.Animals eating those plants in turn absorb Carbon-14 as well as the stable isotopes.
