Examples of equations of carbon dating
In other words, we have a ‘clock’ which starts ticking at the moment something dies.
Obviously this only works for things which once contained carbon—it can’t be used to date rocks and minerals, for example. We obviously need to know this to be able to work out at what point the ‘clock’ began to tick.
The age of geological specimens,which can be many millions of years old,is determined from the proportion of a natural radio nuclide (with a very long half life ) and its daughter nuclide contained in a sample of rock or mineral.
C, we find that this ratio 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.
Any of several methods for determining the age of archaeological and fossil remains,rocks,etc,by measuring some property of the organic or inorganic matter that changes with time.
This property may be dependent on some aspect of nuclear decay,such as the decay of the radiocarbon or the uranium series ,thermo luminescence ,or electron spin resonance.
Consider this—if a specimen is older than 50,000 years, it has been calculated, it would have such a small amount of C that for practical purposes it would show an ‘infinite’ radiocarbon age. Readers are referred to this article for other interesting conclusions about these dates.
