Radiometric and radiocarbon dating
Using the largest set of radiocarbon dates ever obtained from a single Maya site, a team of archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to ...
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).
The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.
A form of radiometric dating used to determine the age of organic remains in ancient objects, such as archaeological specimens, on the basis of the half-life of carbon-14 and a comparison between the ratio of carbon-12 to carbon-14 in a sample of the remains to the known ratio in living organisms. A technique for measuring the age of organic remains based on the rate of decay of carbon 14.
The carbon 14 present in an organism at the time of its death decays at a steady rate, and so the age of the remains can be calculated from the amount of carbon 14 that is left. The cells of all living things contain carbon atoms that they take in from their environment.
Gihon Spring was crucial to the survival of its inhabitants, and archaeologists had uncovered the remains of a massive stone tower built to guard this vital water supply. In a new paper, the authors explain how harvesting data from tree-rings could revolutionize the study of ancient civilizations such as the Egyptian and Mayan worlds. Researchers have used radiocarbon measured in deep-sea fossil corals to shed light on carbon dioxide levels during Earth's last deglaciation.
