Carbon dating maximum age
All dating methods rely on the principle that a parent element decays into a daughter element, for example, uranium to lead.
Scientists know the rate of decay so they use that to estimate age.
The C14 technique has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.
Libby of the University of Chicago in immediate post-WW2 years.
Carbon dating can only measure the age of things that were once alive, like bone, wood, etc. Therefore, the maximum age that carbon dating can measure is about 80,000 years...
no where near the millions of years needed to prove very old ages.
These isotopes are present in the following amounts C12 - 98.89%, C13 - 1.11% and C14 - 0.00000000010%.
Thus, one carbon 14 atom exists in nature for every 1,000,000,000,000 C12 atoms in living material.
