Since carbon is fundamental to life, occurring along with hydrogen in all organic compounds, the detection of such an isotope might form the basis for a method to establish the age of ancient materials.

Libby, a Professor of Chemistry at the University of Chicago, predicted that a radioactive isotope of carbon, known as carbon-14, would be found to occur in nature.

The ensuing atomic interactions create a steady supply of c14 that rapidly diffuses throughout the atmosphere.

Plants take up c14 along with other carbon isotopes during photosynthesis in the proportions that occur in the atmosphere; animals acquire c14 by eating the plants (or other animals).

The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.

Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.

BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.

What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?

"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.
