Two RBMK-1500 reactor units operated in Lithuania in the 1987–2004 period (one of them was stopped for decommissioning in 2004). This study presents a preliminary investigation of surface deposition density levels of 55Fe and 63Ni in moss samples collected in the close vicinity of the Ignalina NPP. Non-destructive analysis by the HPGe gamma-spectrometry was followed by radiochemical separation.
Radiochemical analysis was based on anion-exchange and extraction chromatography. 55Fe and 63Ni activities were measured by liquid scintillation counting (LSC). The results indicate that the deposition values of 55Fe are generally higher than those of 60Co and 63Ni.
