“…The study areas (the Stratoni and Ierissos beaches) are situated in the Ierissos Gulf in the Chalkidiki Peninsula in northern Greece (Figure 1). A description of the study area's characteristics is included in the details elsewhere [9,11]. Briefly, the city of Stratoni is located at the north part of the Ierissos Gulf, where a polymetallic mine is located.…”

“…On the other hand, Ierissos is situated in the southern part of Stratoni, and it mainly hosts tourist activities. A detailed description of the study areas can be found in the literature [9,11]. The beach sand that is located in the site of Stratoni is undergoing a remediation process due to the past mining activities.…”

“…Other studies have focused on the use of natural radionuclides in sediments as tracers for the identification of transport pathways though sediments in coastal areas [6][7][8]. In recent years, the reconstruction of past events [9][10][11] have been performed, analyzing core sediments in terms of sedimentation and accumulation rates to assess the temporal evolution of the environmental status and how is related with global environmental priorities such as climate change [12] and marine pollution studies [10,11]. 137 Cs is an artificial radionuclide with a half-life of 30.1 years.…”

“…Active mining activities located in Stratoni include the mines of Madem Lakkos, Mavres Petres, Olympias [11], the metal floatation plant in the coastal part of Stratoni town, the loading docks in Stratoni's port, and solid waste byproducts [16]. The mine tailings were dispersed directly into the nearshore of Stratoni's marine environment until 1983 [16].…”

In recent years, the environmental effects of both active and legacy mining activity have motivated many research groups worldwide through the use of a variety of methods that have been conducted among diverse environments. In this study, we measured radionuclide concentrations at two coastline locations of the Northern Aegean Sea: Stratoni and Ierissos. We deployed KATERINA II, an in situ gamma ray spectrometer. Our results indicate that the activity concentration for 238U progenies (214Bi), 232Th progenies (208Tl and 228Ac) and 40K vary by up to (33 ± 4) Bq kg−1, (19 ± 3) Bq kg−1, and (420 ± 30) Bq kg−1, respectively. The activity concentration of the 137Cs in Stratoni and Ierissos beach sands were (8.1 ± 2.2) and (3.9 ± 1.2) Bq kg−1, respectively. Lab-based measurements were also collected prior to the in situ data collection for the determination of radionuclide and metal concentrations. The lab-based data were found to be (800 ± 40) μg g−1 and (12 ± 1) μg g−1, for As, (1200 ± 60) μg g−1 and (33.3 ± 0.3) μg g−1 for Pb, (100 ± 6) μg g−1 and (6.0± 0.3) μg g−1 for Cu and (2000 ± 60) μg g−1 and (8.0 ± 0.4) μg g−1 for Zn, respectively. We used the R language and environment for statistical computing to produce radiological maps of the subject beach sands. We used the Enrichment Factor (EF) to estimate assessment indices for the target area and compared them to internationally recommended values. The in situ maps will be discussed since the beach area of the load-out pier area of Stratoni was undergoing the first phase of active remediation. We conclude that the temporal aspect of this dataset can be of significant reference value against future comparative studies after the remediation of the Stratoni beach with potentially denser spatial and temporal data coverage.
