Carbon 14 dating is reliable for rocks that are
But that's not really how it is when scientists are working in their labs.To understand how the C-14 clock works and what processes are involved, let us consider the egg-timer.One also assumes that all the sand is in the bottom of the glass when one turns it over. He must look for something in the bone which disappears over time, as the sand disappeared from the top chamber of the egg timer.The disappearance must take place at a known and measurable rate.
This method, which received widespread attention in connection with the Dead Sea Scrolls, relies on the fact that all living things take in carbon, some of which is very slightly radioactive. To hear some people tell it, scientists have nearly absolute confidence in the dating methods they use.Such raw ages can be calibrated to give calendar dates.One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites.Why are there discrepancies in results when using this method?- by Mike Snavely A question I am often asked at seminars relates to the radiocarbon method of dating old things.
