On April 26, 2007 this facility celebrated 25 years of operation, during which time it had processed over 75,000 radiocarbon measurements on objects ranging from the Dead Sea Scrolls to the Shroud of Turin.Their commercial rate (in 2008) is 5.00 per sample, which somewhat limits its accessibility to chronically under-funded archeological research projects.

Dating has, however, proved problematic because of observed discrepancies between timelines derived from archaeological evidence and those based on radiocarbon dating () because it places the event earlier in time than certain archaeological synchronizations between sites in the Aegean, Egypt, and Levant would suggest possible.Carbon has an atomic number of 6, an atomic weight of 12.011, and has three isotopes: carbon-12, carbon-13, and carbon-14.(The numbers 12, 13 and 14 refer to the total number of protons plus neutrons in the atom's nucleus.This dramatically improves accuracy, and reduces the amount of carbon required from about 10 grams to only a few milligrams.In recent years, dating methods based on cosmogenic isotopes other than carbon (such as beryllium-10 and chlorine-36) have been developed, which allow for the dating of a wider variety of objects over much longer time scales.
