Does radiocarbon dating work

For teaching and sharing purposes, readers are advised to supplement these historic articles with more up-to-date ones suggested in the Related Articles below.by Dr Carl Wieland An attempt to explain this very important method of dating and the way in which, when fully understood, it supports a ‘short’ timescale.

Until this century, relative dating was the only technique for identifying the age of a truly ancient object.Materials that originally came from living things, such as wood and natural fibres, can be dated by measuring the amount of carbon-14 they contain.For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.In fact, the whole method is a giant ‘clock’ which seems to put a very young upper limit on the age of the atmosphere.The article is in straightforward language and the non-technical reader could profitably work through it., we find that this ration is the same if we sample a leaf from a tree, or a part of your body.

Think of it like a teaspoon of cocoa mixed into a cake dough—after a while, the ‘ratio’ of cocoa to flour particles would be roughly the same no matter which part of the cake you sampled.The approximate time since the organism died can be worked out by measuring the amount of carbon-14 left in its remains compared to the amount in living organisms.Love-hungry teenagers and archaeologists agree: dating is hard.Laboratory research has shown that the radioactive decay of Carbon-14 occurs in a half-life of 5,73040 years through beta decay that causes the Carbon-14 to revert back to Nitrogen-14.magazine has been continuously published since 1978, we are publishing some of the articles from the archives for historical interest, such as this.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.
