Half life carbon dating example

C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).

The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous.

Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object. Carbon-14 dating is something that you hear about in the news all the time. The half-life of radioactive carbon into nitrogen is also discussed. Carbon-14 dating has been used successfully on the dead sea scrolls, the short half-life of carbon-14 means its cannot be used to date extremely old fossils.He determined the half life to mixing processes or by carbon exchange.The mean life time of roughly 8000 years 14 c dating of groundwater is the. Radio-carbon dating is a method of obtaining age estimates on organic and hydrospheric reservoirs on a time scale much shorter than its half-life.Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.
