Research on carbon dating

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? Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.

Laboratory images Three isotopes of carbon are found in nature; carbon, carbon and carbon Hereafter these isotopes will be referred to as 12C, 13C, and 14C. The half-life is the time taken for an amount of a radioactive isotope to decay to half its original value. A unique characteristic of 14C is that it is constantly formed in the atmosphere. Production and decay 14C atoms are produced in the upper atmosphere where neutrons from cosmic rays knock a proton from nitrogen atoms. Photosynthesis incorporates 14C into plants and therefore animals that eat the plants. From there it is incorporated into shell, corals and other marine organisms.

Use of 14C dating to determine feeding behaviour of enchytraeids There is a lack of information about the trophic position of enchytraeid species, and it is unknown whether their vertical distribution in the soil corresponds to different feeding strategies. This study, for the first time, employs This study, for the first time, employs radiocarbon techniques to investigate the in situ feeding behaviour of enchytraeids.
