Retrospective study of 14C concentration in the vicinity of NPP Jaslovské Bohunice using tree rings and the AMS technique.

Atmospheric radiocarbon has been monitored around the Nuclear Power Plant (NPP) Jaslovské Bohunice (Slovakia) using CO 2 absorption in NaOH solution since 1969. In 2012, tree ring samples were collected from Tilia cordata using an increment borer at Žlkovce monitoring station situated close to the Bohunice NPP. Each tree ring was identified and graphite targets were produced for 14 C analysis by accelerator mass spectrometry. The 14 C concentrations obtained from the tree-ring samples have been in a reasonable agreement with the averaged annual 14 C concentrations in atmospheric CO 2 . [ABSTRACT FROM AUTHOR]
