The technique the scientists use is known as radiocarbon dating and is more commonly used by archaeologists to date ancient fragments of bone and wood. ❋ Unknown (2009)
Carbon dating (aka radiocarbon dating) is pretty reliable, when the samples are good, up to 30 or 40 thousand years ago, and in some cases the method can be extended to just over 100 thousand years ago. ❋ Unknown (2008)
Everyone assumes that dates that follow the word "radiocarbon" are accurate, precise and sure. ❋ Unknown (2010)
The process has a huge advantage over standard methods such as radiocarbon dating, which is plagued by large error ranges, Kirch said. ❋ Unknown (2010)
Scholars have cast doubt on the Shroud of Turin's authenticity, citing scientific evidence such as radiocarbon testing that date it to medieval times. ❋ Unknown (2009)
'Traditional methods of dating the pigments, such as radiocarbon, are destructive to the paintings, and the samples are prone to contamination. ❋ Unknown (2008)
Now the Monroe County Medical Examiner's office said the results of radiocarbon dating tests are in and the bones are much older -- about 2,400 years -- placing them in the time period of 200-440 B.C. ❋ The Huffington Post News Editors (2011)
It is the stuff of coal, soot, diamonds, radiocarbon dating, pencils, climate change, graphite lubricants, charcoal – and a startling number of Nobel prizes. ❋ Robin McKie (2010)
In one case, a recent project that used high-resolution radiocarbon dating of remains found in the West Kennet barrow – an ancient burial chamber in Wiltshire that was constructed around 3500BC – led to a dramatic re-evaluation of its contents. ❋ Robin McKie (2010)
The radiocarbon assay of charcoal from one of these fire pits gave an age of 1580 +/- 40 B.P. Deryl noticed two other fire pit areas a few hundred feet farther back from the river on the north slope of the ridge. ❋ Annie Proulx (2011)
During the homily, the Pope revealed that a special minuscule probe has been inserted into the sarcophagus of St. Paul, which has never been opened, and a radiocarbon examination of a very small piece of bone retrieved in this way, along with traces of precious vesmtents and incense, has shown that the bones belong to a person who lived between the first and second century. ❋ Unknown (2009)
Once state archaeologists were called in, 101 canoes or partial canoes were found and studied, their positions mapped and samples of their wood radiocarbon dated. ❋ Stuart Ferguson (2011)
A sample of bone from the body was sent to a lab for radiocarbon dating, yielding the same age. ❋ Unknown (2011)
But in their fourth year of field work, they obtained radiocarbon dates from Anakena Beach, thought to be the island's oldest settlement. ❋ Charles C. Mann (2011)
