Standard calibration curves are now used for more accurate readings.These curves indicate the changes in Carbon-14 throughout the years and modifies the end result of the tests to reflect that.

Unfortunately, the amount of Carbon-14 in the atmosphere has not been steady throughout history.Despite its overuse and misrepresentation in the media, it is nonetheless extremely valuable.This process has seriously assisted archaeologists in their research, excavations, and scholarly studies.They risk seriously altering the result of the test.The “Old Wood Problem” is the last flaw of radiocarbon dating that will be elaborated upon here.It consists in comparing and matching two or more series of ring widths measured on different trees.

The partial overlap of sets of trees that died at different times allows the construction of average chronological sequences (courtesy Groupe de recherche en dendrochronologie historique; illustration C.

Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.

Crossdating is an important principle in dendrochronology.

If an archaeologist wanted to date a dead tree to see when humans used it to build tools, their readings would be significantly thrown off.

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!

Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities.
