Hello Listmember,
I am relatively new to the radiogenic part of carbon isotopes and am a bit puzzled on how to estimate MRT of carbon that includes much modern (bomb) carbon (i.e. has negative DEL 14C values). My data range from 111.7% modern to 99.62% modern.

Somehow, I have difficulty finding the formula in the literature, whenever such calculations are published that include the decay of bomb carbon in estimation of MRT.

much thanks for any replies.
