Radio carbon dating for dummies

Because Libby believed that the Earth was millions of years old, he assumed that there had been plenty of time for the system to be in equilibrium.

This means that he thought that C was entering the atmosphere as fast as it was leaving—calculations show that this should take place in about 30,000 years, and of course the Earth was much older than that, said the geologists.

The model of radiocarbon dating which Libby developed, using his incorrect ‘uniform’ assumption, must therefore be corrected to fit the facts about C to start with, so they have an even greater error.

In other words, the further you go back, the more you have to shrink the radiocarbon dates to make them fit the facts.

Imagine the same tank, this time it is not yet full and the top tap is flowing more quickly than the bottom one is leaking out—this gives you a way of measuring how long ago the whole system was ‘switched on’ and it also tells you that that can’t have been too long ago (see diagram above).

In other words, we have a ‘clock’ which starts ticking at the moment something dies.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 fact that the C doesn’t matter in a living thing—because it is constantly exchanging carbon with its surroundings, the ‘mixture’ will be the same as in the atmosphere and in all living things.Imagine a tank with water flowing in at a certain rate, and flowing out again at the same rate (see diagram below). If you saw it for the first time, you wouldn’t be able to work out how old it was—how long it had been since it was ‘switched on’.

was entering the system some 12-20% faster than it was leaving.
