The sediment samples were dried and ground to a fine powder. Airtight sealed samples were counted by gamma-spectrometer with 110 cm3 well-type HPGe detector for one week each. By using the isotopic analysis results, sediment accumulation rate was determined. A sedimentation rate of 0.20±0.01 cm·y-1 was determined using 210Pb method and 0.15±0.03 cm·y-1 using 137Cs isotope. Fallout peak from Chernobyl reactor accident, as well as the peaks due to nuclear tests, act as time markers.EnglishCesium 137Lead 210RadioisotopeRadium 226Age determinationChernobyl accidentGamma spectrometryIsotope analysisPowderRomaniaSeaSedimentSedimentationArticle10.1023/B:JRNC.0000015825.67418.18
