Carbon 14 dating inaccurate

The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.

The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

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.

Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.

The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

Though radiocarbon dating clearly enjoys “wide public interest,” it also generates much confusion and discord among Christians, which leads to an obvious question: is Libby’s celebrated work a reliable technique for dating ancient objects?

The short answer is a resounding YES and here’s why.

Libby received the Nobel Prize in Chemistry for his work in 1960.The concept behind radiocarbon dating is rather simple.While organisms live, they incorporate radioactive carbon-14 from the atmosphere. Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.Carbon dating is used to work out the age of organic material — in effect, any living thing.

By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.
