Pros and cons of dating objects with carbon 14
When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age.
Scientists now realize that production of carbon-14 has not been constant over the last 10,000 years, but has changed as the radiation from the sun has changed.
Stuart Piggott, a British archaeologist, excavating near Durington Walls in England, received a radiocarbon date for his site.
The radiocarbon test on a piece of charcoal suggested that Piggott's site was 1000 years older than it actually was.
Conclusive data from the site proved that the radiocarbon test was grossly in error.
Nuclear tests, nuclear reactors and the use of nuclear weapons have also changed the composition of radioisotopes in the air over the last few decades.
First round is for acceptance, no arguments posted here please.
We will have one round to debate, so its pistols at 10 paces.
Scientists check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.
Other methods scientists use include counting rock layers and tree rings.
