Radionuclides Assessment for the Romanian
Black Sea Shelf

Abstract Radionuclides within the environment are not always a point of concern,
in some cases they can be used to trace and identify incidents even long after they
occurred. This reports performs a high resolution spectrometry analyses for several
samples taken from the Black Sea containing seawater and sediments. The results
give us the opportunity to use traceable radionuclides like
137 Cs or
40 K as tracers for
the human activities within the western Black Sea area. Although the presence of
such radioisotopes can be related to the Chernobyl event, results can be differentiated using other radioisotopes associated to the same event but having a specific
timespan since them as the case for
241 Am. Using such tracers one can isolate
events from 30 years ago from the more recent ones.
