There are two main categories of dating methods in archaeology: indirect or relative dating and absolute dating.
In fact, it has fluctuated a great deal over the years.
This variation is caused by both natural processes and human activity.
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.
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.
This is because radiocarbon dating gives the date when the tree ceased its intake of Carbon-14—not when it was being used for weapons and other instruments!
This magnificent technology is the most important innovation in archaeological history.
Archaeologists have the most accurate readings they are likely to ever receive!
Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities.
Though it’s biggest, the calibration problem is not the only flaw of radiocarbon dating.
It consists in comparing and matching two or more series of ring widths measured on different trees.
