Oct 18, · But that assumes that the amount of carbon in the atmosphere was constant — any variation would speed up or slow down the clock. The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the Nobel Prize in Chemistry. Jun 06, · Carbon dating accuracy called into question after major flaw discovery. When the plant or animal that consumed the foliage dies, it stops exchanging carbon with the environment and from there on in it is simply a case of measuring how much carbon 14 has been emitted, giving its age. Carbon dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50, years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

Carbon dating is normally used by archaeologists rather than geologists because it ceases to be accurate at ages over 50,, years. The half life of carbon 14 is about 5, years, so it. Jun 06, · Carbon dating accuracy called into question after major flaw discovery. When the plant or animal that consumed the foliage dies, it stops exchanging carbon with the environment and from there on in it is simply a case of measuring how much carbon 14 has been emitted, giving its age. One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon, or 14 C, or radiocarbon. Carbon is made when cosmic rays knock neutrons out of atomic nuclei in the upper atmosphere. These displaced neutrons, now moving fast, hit ordinary nitrogen (14 N) at lower altitudes, converting it into 14 C. Unlike common carbon (12 C), 14 C is unstable and slowly decays, changing .

Answers to Creationist Attacks on Carbon Dating. Other species of trees corroborate the work that Ferguson did with bristlecone pines. Before his work, the tree-ring sequence of the sequoias had been worked out back to BC. The archaeological ring sequence had been worked out back to 59 BC. The other major factor affecting the results of carbon dating is gauging the original proportion of carbon itself. Carbon dating is based on the loss of carbon, so, even if the present amount in a specimen can be detected accurately, we must still know how much carbon the organism started with. Scientists must assume how much carbon was in the organism when it died. The result is that carbon dating is accurate for only a few thousand years. Anything beyond that is questionable. This fact is born out in how carbon dating results .
