I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.They used pottery and other materials in sites to date 'relatively'.They thought that sites which had the same kinds of pots and tools would be the same age.It is called 'radio'-carbon, because it is 'radioactive'.This means that its atomic structure is not stable and there is an uneasy relationship between the particles in the nucleus of the atom itself.Carbon follows this pathway through the food chain on Earth so that all living things are using carbon, building their bodies until they die.A tiny part of the carbon on the Earth is called Carbon-14 (C14), or radiocarbon.

Libby of the University of Chicago after the end of World War 2.Eventually, a particle is emitted from the carbon 14 atom, and carbon 14 disappears.Most of the carbon on Earth exists in a slightly different atomic form, although it is chemically speaking, identical to all carbon.The carbon-14 method was developed by the American physicist Willard F. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.

Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
