Ive had a number of questions recently about ‘Radio carbon dating at Stonehenge’ Here is a comprehensive anwser: Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object.
A man called Willard F Libby pioneered it at the University of Chicago in the 50’s. This is now the most widely used method of age estimation in the field of archaeology.

Others have argued that the monument was a shrine to worship ancestors, or a calendar to mark the solstices.
A documentary following the progress of the recent dig has been recorded by the BBC Timewatch series. Date demand For centuries, archaeologists have marvelled at the construction of Stonehenge, which lies on Salisbury Plain, Wiltshire.
The dating is the major finding from an excavation inside the henge by Profs Tim Darvill and Geoff Wainwright.
The duo found evidence suggesting Stonehenge was a centre of healing.
Half of the available atoms will change in a given period of time, known as the half-life.By counting how many carbon-14 atoms in any object with carbon in it, we can work out how old the object is – or how long ago it died.So we only have to know two things, the half-life of carbon-14 and how many carbon-14 atoms the object had before it died. However knowing how many carbon-14 atoms something had before it died can only be guessed at.Ocean sediment C-14 data The Lamont-Doherty Earth Observatory of Columbia University has compiled 974 C-14 dates from 309 ocean sediments cores, covering the period from 40,000 years BP to the present worldwide. The USGS Bear Lake Project aims to create records of past climate change for the Bear Lake region,including changes in precipitation patterns during the last 10,000 years and how the size of Bear Lake has varied in the past, to assess the possibility of future flooding and drought.Archaeologists are closer to discovering how and why the mysterious edifice known as Stonehenge was built after having pinpointed its construction to 2300BC.
