WebOct 10, 2024 · I understand that all living beings have the same proportion of carbon 12 to carbon 14 and that this is an assumption used to carry out carbon dating but I do not understand how this is possible. As isotopes are not evenly distributed, how can it be that the proportion of carbon 14 is the same in all living beings?
WebThe ratio of normal carbon (carbon-12) to carbon-14 in the air and in all living things at any given time is nearly constant. Maybe one in a trillion carbon atoms are carbon-14.
