This study aims to evaluate the activity concentrationsof  238 U,  226 Ra,  232 Th,  228 Th and  40 K along thebeaches of Kavala being adjacent to the rock-types of theKavala pluton. These ranged from 14–940, 16–1710, 26–4547, 27–4488 and 194–1307 Bq/kg respectively, representingthe highest values of natural radioactivity measuredin sediments of Greece. The (%wt.) heavy magnetic (HM)(allanite, amphibole, mica, clinopyroxene, magnetite andhematite) fraction, the heavy non-magnetic (HNM) (monazite,zircon, titanite and apatite) fraction and the totalheavy fraction (TH), were correlated with the concentrationsof the measured radionuclides in the bulk samples.The heavy fractions seem to control the activity concentrationsof  238 U and 232Th of all the samples, showingsome local differences in the main  238 U and  232 Th mineralcarrier. The measured radionuclides in the beach sandswere normalized to the respective values measured in thegranitic rocks, which are their most probable parentalrocks, so as to provide data upon their enrichment or depletion.The annual equivalent dose varies between 0.01and 0.35 mSv y −1  for tourists and from 0.03 to 1.48 mSv y −1 for local people working on the beach.
