The Age Of Any Remains From A Once Living Organism Can Be Determined By Radiocarbon Dating A Procedure That Works By De 1 (35.85 KiB) Viewed 14 times

The age of any remains from a once-living organism can be determined by radiocarbon dating, a procedure that works by determining the concentration of radioactive C in the remains. All living organisms contain an equilibrium concentration of radioactive C that gives rise to an average of 15.3 mg of carbon. (These nuclear decay events are used as concentrations for any calculations.) At death, however, no additional 4C is taken in, so the concentration slowly drops as radioactive decay occurs. A bone fragment has been found on the planet's surface and shows an average of 2.3 mg of carbon. If the half-life for the radioactive decay of C is 5715 years how old is the bone fragment?
