Wikipedia carbon 14 dating
There are many sports restricted to players of a certain age (e.g.
16 and under, 18 and under, etc.) What if a person is older and fakes his birth certificate to say that he is younger? Can we determine such a person's age by radiocarbon dating methods or other means? That doesn't mean we can't make a decent guess by other methods.
That’s because some cells are born after you are, sometimes many many years after, but we’re not really sure which ones, or when — it’s not as if there are cellular birthday parties, marked by balloons and cake.
So the question of age remained relatively unanswered until the early aughts, when scientist While Mary Webster has a very interesting analysis of tissue age, she is apparently unaware of the natural production of C-14 by cosmic rays in the upper atmosphere.
, and is so rare that only one-in-a-trillion carbon atoms are carbon-14.
With a half-life of just over 5,000 years, any Carbon-14 atoms that were created in stars, billions of years ago, have long since decayed away into nitrogen atoms.
I understand that the method can provide dating up to ca.
I have read that this difficulty in the young-sample range is due to the fact that not enough material has been depleted to calculate accurately. Or more precisely, how old are your cells..cells in your liver, or your spleen, or your brain?It's a question that's harder to answer than you think.I am a paintings conservator and have been requested to examine a panel painting from approximately 1550 A.D., and I have dendrochronological evidence which supports this date.
About 1.1% of all carbon is Carbon-13, with one extra neutron.
