The C14 present in the object then decays without being replenished.
So an old organic relic will have a lower percentage of C14 than a more recent one.
Some of the decays will produce high-energy electrons, either directly or indirectly.
The cosmic rays would therefore have been augmented by the presence of radiation sources from atomic tests, but this is irrelevant for carbon dating, which is not useful for objects less than 200 years old anyway.
Posted by Eileen on : There is currently a debate raging on the AOL Anthropology message board regarding Creation vs. Many of the creationists point to an event where it's claimed that someone planted a chicken bone and it was radiocarbon-dated to a ridiculous age, thus invalidating this technique.
Someone else mentioned this might be an urban legend, and I'd love to be able to say it is. Thanks Posted by Grumpy on : A clam shell would be a legitimate anomaly.
Carbon dating makes several assumptions which could only be 100% in a controlled environment.
That said, I don't beleive the chicken bone story is even partially true.
They have far higher energies and cause different decay byproducts if they are absorbed by anything, IMSC.
Posted by First of Two on : The Big Bang was 15 billion years ago, and only a few hundred entities were around to observe it. Your friend probably actually witnessed the 'bang' that accompanied the fusion ignition of the sun, roughly 4.5 billion years ago.

As I understand it, marine mollusks absorb carbon from seawater, which has a different isotopic ratio than air.
Which is why you'll see the claim that living snails appear to be thousands of years old when tested. Indeed, if the chicken bone anomaly is valid, it should probably be in the scientific literature, as it would provide a refinement of the procedure.Or it would prove radiocarbon dating inaccurate altogether, since I'm sure nobody ever thought to test a fresh sample before (and lived to report it!
