Calibration is then done to convert BP years into calendar years.This information is then related to true historical dates.Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.Before deciding on using carbon dating as an analytical method, an archaeologist must first make sure that the results of radiocarbon dating after calibration can provide the needed answers to the archaeological questions asked.

Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.

Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences.

But archaeology’s aim to understand mankind is a noble endeavor that goes beyond uncovering buried treasures, gathering information, and dating events.

Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.

Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.
