Although relative dating can work well in certain areas, several problems arise.
This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. The short half-life of carbon-14 means its cannot be used to date extremely old fossils.All radioactive atoms eventually decay into something more stable, and carbon-14 decays into nitrogen.For a rare event it happens pretty damn often — one million carbon-14 atoms in your body decay into nitrogen every minute!The Muslims count the Prophet’s departure from Mecca, or the Hegira, as their beginning at AD 662.The Mayan calendar used 3114 BC as their reference.When these neutrons collide with nitrogen-14 in the atmosphere carbon-14 can be created.
Nitrogen normally occurs in a seven proton, seven nuetron, nitrogen-14 state. Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old. Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.When it comes to dating archaeological samples, several timescale problems arise.Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharohs among other things. 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 remains undecayed).
