During the lifetime of an organism, the amount of c14 in the tissues remains at an equilibrium since the loss (through radioactive decay) is balanced by the gain (through uptake via photosynthesis or consumption of organically fixed carbon).However, when the organism dies, the amount of c14 declines such that the longer the time since death the lower the levels of c14 in organic tissue.So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living.Accessed 2013 Jul 2" href="#footnote2_bu6j0pd" Both the carbon-14 dating results and the discovery of soft tissue in incompletely fossilized dinosaur bones share the common theme of being indicators of much younger ages for dinosaurs than evolution claims.Compared to the conventional theory of dinosaurs’ being at minimum 65 million years old, the time it would take soft tissue to degrade and the Each of the two thousand meeting participants was given a disc which included the abstract of the carbon-14 dating report.Following death, however, no new carbon is consumed.

In contrast, methane made from petroleum products had no measurable radioactivity.Although, organic materials as old as 100,000 years potentially can be dated with AMS, dates older than 60,000 years are still rare.Paleoanthropologists and archaeologists must always be aware of possible radiocarbon sample contamination that could result in inaccurate dates.This discovery meant that there are three naturally occurring isotopes of carbon: Whereas carbon-12 and carbon-13 are stable isotopes, carbon-14 is unstable or radioactive.Carbon-14 is produced in the upper atmosphere when cosmic rays bombard nitrogen atoms.
