Acuracy of carbon dating Perveted sex chat
Why was carbon chosen for the dating method, out of all the radioactive elements?One reason is the fact that it has a radioactive isotope and second reason is that life is based on carbon compounds.The impact of this technique on the world of science, led to Libby being awarded the Nobel prize in chemistry, in 1960.This dating method is based on comparison of ratios of two carbon isotopes, which are C-12 and C-14. Isotopes are elements with the same atomic number, but different atomic mass numbers. By comparing the amount of radioactive carbon present now, with the amount at the beginning, an age estimate can be made, based on laws of radioactive decay.The fact that scientific methods like these, fail beyond a certain domain of approximation, doesn't make them redundant.It only means that these need to be used with caution and with a knowledge of the limits of their accuracy.Hence, the ages are specified as 3400 BP (3400 years BP). The flaw in this method is that it assumes that the carbon-14/carbon-12 ratio has been the same till 1950, which is not the case in reality.
Contamination disturbs the ratio of carbon isotopes found in situ, in the sample.It is doubted due to certain perceived flaws in its fundamental assumptions and ambiguous results.Carbon dating is a technique to determine the age of archeological objects, fossils, or any remnant from the past. This was developed by Willard Libby and his associates, in 1949.Still, this changing ratio of carbon isotopes, does make a minuscule dent in the calculation accuracy.There is another possibility, which may affect the accuracy of this dating method.
