Poznan radiocarbon dating laboratory
The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.
Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
(1) Fax: The isotope with mass 14 (Carbon 14), known as radiocarbon, is one of the unstable isotopes of carbon with widespread applications in the scientific world. Measuring carbon14 levels in human tissue could help forensic scientists determine age and year of death in cases involving unidentified human remains. 8 % of all carbon atoms, carbon13 accounts for 1% of carbon atoms while 1 in every 1 billion carbon atoms is carbon14.

Measuring carbon14 levels in human tissue could help forensic scientists determine age and year of death in cases involving unidentified human remains. The Shroud of Turin, a linen cloth that tradition associates with the crucifixion and burial of Jesus, has undergone numerous scientific tests, the most notable of which is radiocarbon dating, in an attempt to determine the relics authenticity.
