All D14C values are normalized to the base value of -25.0 per mille with respect to the standard carbonate (VPDB).D14C is calculated using: Figure 1: Decay curve for C14 showing the activity at one half-life (t/2).Beukens (1994) for instance has stated that this means the limit of the range for his Isotrace laboratory is 60 000 yr which is very similar to the conventional range.

Background samples usually consist of geological samples of infinite age such as coal, lignite, limestone, ancient carbonate, athracite, marble or swamp wood.

The Conventional Radiocarbon Age BP is calculated using the radiocarbon decay equation: Where -8033 represents the mean lifetime of 14C (Stuiver and Polach, 1977).
