"Baker Shot", part of Operation Crossroads, a nuclear test by the United States at Bikini Atoll in 1946.

Since 2005 the lab ceased to perform radiocarbon measurement by the liquid scintillation counting technique which determined 14C activity via the measurement of beta decay.

This method required samples of greater than c. 1 g of carbon and since the changing needs of the user community have been for the analysis of progressively smaller samples, the lab now concentrates on analysis using AMS only.

It is important to note that the lab still retains the ability to analyse all large samples that would previously have been measured using the radiometric method.
