AbstractAbstract
[en] Samples of marine surface sediments of different grain sizes collected in Goekova, a small bay on the Aegean Turkish Coast, have been examined to measure alpha- and gamma-radioactivity. The purpose of this research is to define a baseline study of man-made radionuclides on sediments along Goekova Bay, using a combination of direct gamma-spectrometry, radiochemical separation and alpha spectrometry. The analysis of these samples revealed measurable quantities of some artificial radionuclides namely: 239+240Pu (from 0.13 ± 0.017 to 0.85 ± 0.15 Bq x kg-1). 137Cs, 241Am and 238Pu were identified at a very low level. Concentration ratios of 238Pu to 239+240Pu obtained seem to confirm that this artificial radioactivity is due mainly to Chernobyl accident. (author)
