Sample collection

It is important that there is a connection between the event dated with 14C ('time of death') and the historic or environmental event wished to be dated. Thus short lived materials are preferred over long lived materials which may have a considerable own age.

Equally important the sample material should ideally be chosen such that the carbon originates directly from atmospheric CO2. Hence terrestrial materials are preferred over marine materials.
