heal.abstract	Sediment samples have been collected in the Butrint area, located in the south-west Albania to determine the radioactivity levels of K-40, (CS)-C-137, Bi-212, Pb-212, Bi-214, Pb-214, Ra-226 and Ac-228 on the bed of the lagoon and adjacent sea, using direct counting gamma spectroscopy. The concentration of Cs-137 and 40K varied from 2.8 to 37.5 Bq/kg and from 266 to 675 Bq/kg dry weight (dw), respectively (central values). The average concentrations of U-238 and Th-232 daughter products varied from 8 to 27 Bq/kg and from 13 to 40 Bq/kg dw, respectively. The measured U-235 activity ranged from 0.7 to 2.5 Bq/kg dw. Samples of different sedimentary properties, studied for the radioactivity concentration, revealed an inversely proportional relation between grain size and a linear combination of measured specific activities of Ra-226, Th-232 (Ac-228, Bi-212 and Pb-212), K-40 and (CS)-C-137.
