Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.

Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.

When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.

Radiocarbon dating is essentially a method designed to measure residual radioactivity.

Liquid scintillation counting is another radiocarbon dating technique that was popular in the 1960s.

In this method, the sample is in liquid form and a scintillator is added.

Nov 27, 2012. Dating history. When living things die, tissue is no longer being replaced and the radioactive decay of 14C becomes apparent. Around 55,000 years later, so much 14C has decayed that what remains can no longer be measured. Radioactive decay can be used as a “clock” because it is unaffected by.… continue reading »
