Carbon dating nuclear
It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.
Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon-14" or any other material containing artificial Carbon-14 to eliminate the risk of cross-contamination.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.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.

American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.
