Do you really want to walk around with an increased radioactivity level for that long??

Of course a small fraction of the carbon atoms in your body are carbon 14 so you are already radioactive!!

The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.

The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.

...prehistoric archaeology occurred in 1948, when Willard F.

Libby, at the University of Chicago, developed the process of radioactive carbon dating.

Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.

The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

Another isotope, carbon-14, is useful in studying abnormalities of metabolism that underlie diabetes, gout, anemia, and acromegaly.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.Various scanning devices and techniques have been developed, including tomography...P) have been valuable in identifying the intermediate compounds formed during carbon assimilation.Work, so they are dating useful eager to share this new platform with.
