How Does Carbon Dating Work Carbon is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C dating is only applicable to organic and some inorganic materials not applicable to metals. Gas proportional counting, liquid scintillation counting and accelerator mass spectrometry are the three principal radiocarbon dating methods. What is Radiocarbon Dating?
Carbon Dating Gets a Reset
Unreliability of Radiometric Dating and Old Age of the Earth
From Nature magazine The carbon clock is getting reset. 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. The technique hinges on carbon, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
Antero wrote this article in response to the History Channel documentary titled, "The Jesus Strand: A Search for DNA. I sent that link to Antero and he replied, "I read it and my opinion is quite similar to yours and my paper also deals with the speculations of that documentary. English speakers can use an online translation service to read the article. Of course, several other papers have been published recently and we are including them as well.
How did Libby test his method and find out if it worked correctly? Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known. A sample of acacia wood from the tomb of the pharoah Zoser was dated for example. Zoser lived during the 3rd Dynasty in Egypt BC. The results they obtained indicated this was the case.
