Several radionuclides (/sup 90/Sr, /sup 137/Cs, /sup 144/Ce, /sup 155/ Eu, /sup 147/Pm, /sup 54/Mn, and /sup 226/Ra) were determined in plankton and seawater samples: their content is in relation to the radioactive fallout intensity. Particular attention was paid to /sup 90/Sr the presence of which in the plankton may be correlated with the Acantharia frequency. Such a radionuclide was determined in many marine substrata also. The same radionuclides were found in the coastal marine sediments of the Ligurian and North Adriatic Seas. The radioactivity due to their presence in the various layers was correlated with the radioactive fallout and suggested to us an hypothesis on the accumulation rate of marine sediments in the coastal zones. In 1968 the radioecological study of Taranto Gulf was begun. The value of the radioactivity measurements in such a zone has a practical importance as in future a reprocessing plant of the nuclear iuel will start to operate at Rotondella, with a consequent release of radioactive wastes in the Jonian Sea. A fresh water environment was also considered, the Lago Santo Parmense. The radioactivity measured in the various substrata (sediment, water, vegetables) is by far higher than the one of the marine environment. In particular the /sup 137/Cs contribution to the sediment radioactivity is remarkable. (auth)
