Fraction Modern is the measured deviation of the 14C/12C ratio from Modern. Modern is defined as 95% of the 14C concentration of the National Bureau of Standards Oxalic Acid I standard (SRM 4990B) normalized to d13C VPDB (-19ppm) in 1950 AD (VPDB = Vienna Pee Dee Belemnite geological standard.

Report the D14C value as defined in Stuiver and Pollach (1977) as the relative difference between the absolute international standard (base year 1950) and sample activity corrected for age and d13C. The D14C is age corrected to account for decay that took place between collection (or death) and the time of measurement so that two measurements of the same sample made years apart will produce the same calculated D14C result. Collection year must be specified in order for D14C results to be calculated.
