Examples inaccurate carbon dating
The level of atmospheric Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.A favorite tactic of Young-Earthers involves citing studies which show trace amounts of Indeed, this results from a unique decay mode known as "cluster decay" where a given isotope emits a particle heavier than an alpha particle (radium-226 is an example.) This fact is extremely inconvenient and creationist literature, accordingly, usually does not mention it.
As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.
Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.
In the presentation speech for the 1960 Nobel Prize in Chemistry, one scientist described the work by honoree Willard Libby with these words: “Seldom has a single discovery in chemistry had such an impact on the thinking of so many fields of human endeavour.
Seldom has a single discovery generated such wide public interest.” Libby’s research demonstrated the usefulness of carbon-14 in dating samples thousands of years old.
The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.
Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.
Furthermore, if a sample has been contaminated, scientists will know about it.
Ironically, given how supposedly useless carbon dating is claimed to be, Creation Ministries International rests part of their "101 Evidences" on carbon dating being a useful method for within several thousand years.
By measuring the ratio of carbon-14 to stable carbon-12, scientists can then determine when the organism in question died.
When Libby developed the radiocarbon dating technique, he validated the method by comparing measured carbon ratios (carbon-14/carbon-12) from artifacts of known age with predictions of the ratio expected by assuming the decay rate.
The ratio of C-12 to C-14 is approximately 1 billion to one in today’s atmosphere.
