Gamma-ray spectrometers

The aim of the marine radioecology project is:- to study the natural and artificial radioactivity in the marine ecosystem in the Eastern Mediterranean (Aegean, Cyprus, Ionian and Adriatic Seas) and the Black Sea,- to provide a chartography of natural and man made radiation levels in abiotic materials and biota of the marine environment,- to assess the radionuclide transfer through the different trophic links of the marine food chain,- to evaluate the exposure doses received by the Greek population from the consumption of marine foodstuffs and- to evaluate the effects of ionizing radiation on natural aquatic populations in terms of acute and chronic irradiation.The period covered is 1984-2000 for sea water and sediments, (1999-2000) for Cyprus Sea) and 1984-1998 for marine biota. The measured radionuclides are 137Cs (134Cs for 1986 also) and the natural radionuclides of uranium-radium and thorium decay series and 40K as well.
