Radiocarbon dating of fossils taken from

It is not independent of time; it is dependent on geographical location; it is species dependent; the generation activity is changing, and it is subject to contamination.

There have been a number of “correction factors” proposed in attempts to normalize C14 dating.

He first noted that the cells of all living things contain atoms taken in from the organism's environment, including carbon; all organic compounds contain carbon.

Most carbon consists of the isotopes carbon 12 and carbon 13, which are very stable.

Because atmospheric carbon 14 arises at about the same rate that the atom decays, Earth's levels of carbon 14 have remained fairly constant.

Once an organism is dead, however, no new carbon is actively absorbed by its tissues, and its carbon 14 gradually decays.

How much this effects the real date is questionable because of the other variables in the system.

This brief summary of the C14 dating problem shows that the assumptions on which the process was originally established need to be reconsidered.

In a stable environment, the amount of C14 is in equilibrium; that is, the amount of decay equals the amount of new C14 taken in. 17), the magnetic field is decaying as a first order exponential with a half life of 1,400 years, a number much less than the 5,700 year half life of C14.

Archaeologists, anthropologists and others involved in researching things of the past have used the tools of radiocarbon (C14) dating as a supposedly accurate measurement of time in past history by which they could correlate activities from remote parts of the world.
