Therefore, any expression of “before present” will mean “before 1950”.

date of organic material - but an approximate age, usually within a range of a few years either way.

Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.

Stone and metal cannot be dated but pottery may be dated through surviving residue such as food particles or paint that uses organic material (8).

By applying magnetic and electrical fields, the mass of these ions is measured and the accelerator is used to remove ions that might contaminate the dating.

The sample passes through several accelerators in order to remove as many atoms as possible until the C pass into the detector.

As a test, the team took samples of acacia wood from two Egyptian Pharaohs and dated them; the results came back to within what was then a reasonable range: 2800BC /- 250 years whereas the earlier independent dates (largely the dendrochronology records) were 2625 /- 75 years (3), (5).
