Carbon isotopic composition (δ13C and 14C activity) of plant samples in the vicinity of the Slovene nuclear power plant

δ13C values of various plants (apples, wheat, and maize) collected in the vicinity of the Krško Nuclear Power Plant (Slovenia) during 2008 and 2009 were determined. By measuring dried samples and their carbonized counterparts we showed that no significant isotopic fractionation occurs during the carbonization phase of the sample preparation process in the laboratory. The measured δ13C values of the plants were used for δ13C correction of their measured 14C activities.

► Actual δ13C values of plant samples were determined for dried and carbonized samples.
► No significant isotopic fractionation occurred during carbonization process.
► Measured δ13C values were applied for correction of 14C activities.
