For decades after Libby performed the first radiocarbon dating experiments, the only way to measure the 14 C in a sample was to detect the radioactive decay of individual carbon atoms. Measurement of Nthe number of 14 C atoms currently in the sample, allows the calculation of tthe age of the sample, using the equation above. 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. For example, rivers that pass over limestonewhich is mostly composed of calcium carbonatewill acquire carbonate ions. A quiz will test how much we have learned. Teachers Love Study.
