Thanks to Fossil Fuels, Carbon Dating Is in Jeopardy. One Scientist May Have an Easy Fix

Physical Review. Ok More Information. Ask Smithsonian. Korffthen employed at the Franklin Institute in Philadelphiathat the interaction of thermal neutrons with 14 N in the upper atmosphere would create 14 C. Since the calibration curve IntCal also reports past atmospheric 14 C concentration using this conventional age, any conventional ages calibrated against the IntCal curve will produce a correct calibrated age. Carbon 14 is thought to be mainly a product of bombardment of the atmosphere by cosmic rays, so cosmic ray intensity would affect the amount of carbon 14 in the environment at any given time. Accurate tree ring records of age are available for a period extending 9, years into the past.
