Professor Waldron added: 'Using carbon-14
dating like this could give conservationists and land managers a deeper understanding of the effect that development work is having on peatlands.
The above carbon-14
old-age dating is also consistent for very old ages as are obtained from U/Pb radiometric age dating that has been applied to glacial tillites that occur in the recent Ice Age, in the Paleozoic Era, and then farther and farther back in the Precambrian to very old ages.
The fundamental importance of these discoveries was recognized in 1946 with the foundation of the first nuclear reactor at Oak Ridge National Laboratory enabling commercial production of carbon-14
for clinical applications.
It works because of (https://www.britannica.com/science/carbon-14-dating) how carbon-14
decays over time - scientists understand the steady rate at which it disintegrates, so they can measure the element in a tusk to test how long the elephant has been dead.
In the time that follows, the carbon-14
isotope will show up in the subject's DNA, blood, urine or tissue.
isotope ratio of the wine alcohol can therefore be used to determine the vintage of a wine.

Plants and animals absorb trace amounts of radioactive carbon-14
from carbon dioxide (CO2) in the atmosphere while they are alive but stop doing so when they die.
Radiocarbon dating, also known as carbon-14
dating, is a technique that can accurately determine the age of organic material.
produced by above-ground nuclear testing in the 1950s and 1960s has helped researchers from Lawrence Livermore (Calif.) National Laboratory determine that the number of fat cells in the human's body--whether the individual is lean or obese--firmly is established during the teenage years.
There is a different ratio of carbon-14
and carbon-12 in steroid hormones that are made from plant sources compared with animal sources.
