In a new paper published in the journal Scientific Reports,a team of researchers led by the University of Glasgow discuss how they have used carbon-14
dating to determine for the first time the age of carbon dioxide being released from peatland sites.
He said tests on the vodka showed that, following the distillation process, only "natural Carbon-14
" radioactivity was found in line with any normal spirit drink.
However, "because distilling reduces any impurities in the original grain, the only radioactivity the researchers could detect in the alcohol is natural Carbon-14
at the same level you would expect in any spirit drink," Prof.
"Paleontologists who study life from the last 50,000 years or so use a technique called carbon-14
dating to determine the age of a sample.
Radio carbon dating calculates the amount of Carbon-14
in bone and teeth samples and establishes the approximate time when an animal or plant was alive.
The fine article by Gregg Davidson and Ken Wolgemuth explains how we can have confidence in age dating, based on comparisons of independent data sets ("Testing and Verifying Old Age Evidence: Lake Suigetsu Varves, Tree Rings, and Carbon-14
," PSCF 70, no.
The study would require the use of carbon-14
, a radioactive isotope used to trace the age of an artifact, to examine the coffin and its colors.
Every organic compound has a certain amount of carbon-14
(a specific isotope of carbon) in it, and over time, this carbon-14
analysis of samples proved site dates back to 3100 BC
The analysis of carbon-14
dating on the excavated samples reveal that the sites belong to 3100 BC (Hafeet period).
