Is carbon dating reliable
So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.
Carbon from these sources is very low in C-14 because these sources are so old and have not been mixed with fresh carbon from the air.This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles.The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.Thus, a freshly killed mussel has far less C-14 than a freshly killed something else, which is why the C-14 dating method makes freshwater mussels seem older than they really are.
When dating wood there is no such problem because wood gets its carbon straight from the air, complete with a full dose of C-14.
The creationists who quote Kieth and Anderson never tell you this, however.
They believe that neutron radiation caused by an earthquake could have induced the image of a crucified man -- which many people believe to be that of Jesus -- onto the length of linen cloth, and caused Paul Carlsson, a paleometagenomicist working to establish his own career after an abusive childhood at the hands of his scientist father, has never known a world that wasn't 5,800 years old--a figure that, according to his father, had been proven by the Shroud of Turin, the magic bullet and the Kennedy assassination, Romanov bones and DNA matches, Hitler's skull, tracking the killer virus of 1918, testing the Titanic rivets, and identifying Osama bin Laden.
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.
Therefore it should come as no surprise that creationists at the Institute for Creation Research (ICR) have been trying desperately to discredit this method for years.
They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.
