When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles.
The isotope decreased by a small fraction due to the combustion of fossil fuels, among other factors.
However, the quantity of Carbon-14 was nearly doubled in the ’50s and ’60s because of the atomic bomb testings in those decades.
In last Tuesday’s lecture, radiocarbon dating was covered briefly.
It is an essential technology that is heavily involved in archaeology and should be explored in greater depth.
Therefore it should come as no surprise that creationists at the Institute for Creation Research (ICR) have been trying desperately to discredit this method for years.
They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.
Though it is not without its flaws, including several not mentioned here, it is truly an incredible creation that will be used for many years to come.
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.
In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin.
Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws.
In fact, it has fluctuated a great deal over the years.
