The present investigation conducted in Čepkeliai peatland (south-eastern Lithuania) deals with two radioisotope methods – carbon-14 (14C) and tritium (3H). 14C was applied to peatland chronology and sedimentation rate estimation and 3H to peat water dynamics characterization. According to 14C data, peatland development began since 12650-11350 years cal BP and peat accumulation since 10550-9700 years cal BP with peat accumulation rate of 0.27-0.79 mm/year in the central part of the peatland. The peat water mean residence time and basic groundwater flow was estimated to be respectively about 27 ± 6 years and 62 ± 15 mm based on 3H data. The obtained data showed relatively undisturbed natural condition of Čepkeliai peatland in the studied sites.
