Radiocarbon dating artifacts

26 Dec

Radiocarbon or C14 dating employs complex systems of measuring the unstable isotopes in once living matter.There are three forms of carbon that naturally occur forming the building blocks of all plant and animal life.Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).

This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old). Faced with a date for Qeiyafa that confirms the traditional high Bible chronology, the low chronology “minimalists” now desperately argue that Qeiyafa was a Philistine fort tied to the kingdom of Gath, not a border fortress of the early Judahite state. There’s been a lot of debate around the issue of Bible chronology, which more specifically relates to the era of the reigns of David and Solomon.Is radiocarbon dating accuracy indeed more reliable to determine Bible chronology than traditional dating methods that rely on archaeological evidence that looks at strata context? The material’s period of growth might be many decades from the era in which it was used or reused, say, in building construction.The resulting release of carbon dioxide is fed to an accelerator mass spectrometer, which measures the decay of radioactive carbon 14the more the carbon 14 has decayed, the older the object is.Over the past 20 years, chemist Marvin Rowe of Texas A&M University has developed a nondestructive method for carbon dioxide extraction.
