As soon as it dies, however, the C ration gets smaller.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.Radioactive elements were incorporated into the Earth when the Solar System formed.All rocks and minerals contain tiny amounts of these radioactive elements.
The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.
Of all the carbon in the world only a very small amount is radioactive.
Plants are designed to absorb carbon dioxide (what you and I breathe out --.
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.
