Definition of radiocarbon dating for kids

From these records a “calibration curve” can be built (see figure 2, below).

A huge amount of work is currently underway to extend and improve the calibration curve.

This method requires less than 1g of bone, but few countries can afford more than one or two AMSs, which cost more than A0,000.

Australian National University provides funding as a member of The Conversation AU.

In 2008 we could only calibrate radiocarbon dates until 26,000 years.

Now the curve extends (tentatively) to 50,000 years.

The calibrated date is also presented, either in BC or AD or with the unit cal BP (calibrated before present - before 1950).
