Before deciding on using carbon dating as an analytical method, an archaeologist must first make sure that the results of radiocarbon dating after calibration can provide the needed answers to the archaeological questions asked.
Why is carbon 14 used for dating organic materials
Samples that have been radiocarbon dated since the inception of the method include charcoalwoodtwigs, seedsbonesshellsleather, peatlake mud, soilhair, potterypollenwall paintings, corals, blood residues, fabricspaper or parchment, resins, and wateramong others. Around 55, years later, so much 14 C has decayed that what remains can no longer be measured. Radiocarbon Dating and Quaternary History in Britain". There are three principal techniques used to measure carbon 14 content of any given sample— gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry. This means that radiocarbon dates on wood samples can be older than the date at which the tree was felled. Back to Landmarks Main Page.
