Carbon dating and chemistry

A portion of the carbon is the radioactive isotope carbon-14.

At death, the exchange stops, and the carbon-14 then decays with a known half-life, which enables scientists to calculate the time of death.

Based at the University of Wales Trinity St David, he has devoted his career to studying the Quaternary period – the last 2.6 million years and the so-called ‘age of humans’.The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology, and even biomedicine.
