Datarea cu radiocarbon a unei probe de lemn provenite de la Cetatea Giurgiu
Accelerator Mass Spectrometry (AMS) is today the most sensitive isotopic analysis method known.The AMS sensitivity can reach 10-15 scarce isotope (14C)/ abundant isotope (12C), in other words, AMS allows determination of the existence of a single atom in a torrent of one million billion other foreign atoms. So, AMS is an analytical technique for measuring low levels of long-lived radionuclides.Due to its exceptional sensitivity, this method has opened a very wide range of applications in various fields: medicine, archaeology, geology, atmospheric physics, paleoclimatology, astrophysics, nuclear physics, nuclear pollution tracking, etc.The isotope with mass 14, known as radiocarbon, is one of the unstable isotopes of carbon with widespread applications in the scientific world. The use of 14C as a „clock” for estimating the age of various historical and pre-historical samples is one of its most important applications.
