    C ratio of 1.12372%. [2] A related standard is the use of wood, which has a δ 13 C of -25‰, as the material for which radiocarbon ages are calibrated. Since different materials have different δ 13 C values, it is possible for two samples of different materials, of the same age, to have different levels of radioactivity and different 14 C ...
