This technique will not help us if we want to know is still in his life, such as friends talked us through the Internet that claim to 25 years. Determination of age using radiocarbon dating techniques (radiocarbon dating) is useful to determine the remaining life of plant or animal that died about five hundred to fifty thousand years ago.
Since the discovery by a professor of chemistry University of Chicago, Willard F. Libby (1908-1980) around 1950s (he received the Nobel Prize for the discovery in 1960), radiocarbon dating techniques have become very powerful tools in archaeological research, oceanography, and several other disciplines.
For radiocarbon dating techniques to tell the age of an object, that object must contain organic carbon, namely carbon which had been part of the body of plants or animals. Radiocarbon dating methods tell us how long ago the plant or animal life, or more precisely, how long ago the plant or animal dies.
Radiocarbon test can be conducted on materials such as wood, bone, charcoal from the hearth of ancient camp or cave, or even a linen cloth used to wrap mummies, because the linen cloth made from flax plant fibers.
Carbon is a chemical element that was conceived by every living creature in the form of various biochemical substances, in proteins, carbohydrates, lipids, hormones, enzymes, etc.. Indeed, the study of chemistry of carbon-based chemicals called "organic chemistry" because once people believe that the only place for these chemicals are living creatures.
Now, people know that we can make all kinds of carbon-based organic chemicals from petroleum without having to take of plant or animal.
However, carbon in living things differ in one important case of carbon in the materials are not living things such as coal, petroleum, and minerals. Carbon "live" carbon atmospheres containing small amounts of certain types called carbon-14, while the carbon "dead" only contain atoms of carbon-12 and carbon-13.
The three kinds of different carbon atoms are called isotopes of carbon, they all behave the same chemically, but have a different weight, or more precisely, have different masses.
What is unique about the carbon-14, in addition to its mass, is because they are radioactive. Namely, they are unstable and tend to become weak, fragmented firing subatomic particles: particles called beta.
Thus all living things actually are radioactive, although few, that is because it has a carbon-14. Yes, including you and me, we are all radioactive. People with a weight of 68 kg contains about a million billion atoms of carbon-14 that fired a 200 000 beta particles every minute!
