At least to the uninitiated, carbon dating is generally assumed to be a sure-fire way to predict the age of any organism that once lived on our planet.

Without understanding the mechanics of it, we put our blind faith in the words of scientists, who assure us that carbon dating is a reliable method of determining the ages of almost everything around us.

Carbon dating is somewhat accurate because we are able to determine what the ratio was in the unobservable past to a certain extent.

By taking a carboniferous specimen of known age (that is, a specimen which we are able to date with reasonable certainty through some archaeological means), scientists are able to determine what the ratio was during a specimen's lifetime.

Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so - a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.

Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30,000 years ago, or nearly half as long as was hitherto thought.

For example, a steel spearhead cannot be carbon dated, so archaeologists might perform testing on the wooden shaft it was attached to.

This provides good information, but it only indicates how long ago that piece of wood was cut from a living tree.

For over 50 years, scientists and researchers have relied on carbon dating to find the exact age of organic matter.They are then able to calibrate the carbon dating method to produce fairly accurate results.Carbon dating is thus accurate within the timeframe set by other archaeological dating techniques.Carbon dating is reliable within certain parameters but certainly not infallible.When testing an object using radiocarbon dating, several factors have to be considered: First, carbon dating only works on matter that was once alive, and it only determines the approximate date of death for that sample.
