he Adriatic coastline (Shëngjini bay, Lalzi bay, Durrës bay and Spille bay)
is previously investigated for the activity concentration of natural
radionuclides in sand samples by means of high-resolution gamma ray
spectrometry technique. The highest activity concentrations of 40K,
226Ra and 232Th are found to be 458 Bq/kg, 67 Bq/kg and 91 Bq/kg, respectively. This
study aims to investigate the dose rate and elemental composition of beach
sands in order to better understanding of the behaviour of radionuclides in
the coastline of the Adriatic Sea in Albania. The same sand samples are
characterized for the chemical composition by means of X-ray fluorescence
spectrometry (XRF) together with some REEs (rare earth elements). A good
correlation is found between natural radionuclide concentration and REEs in
general giving a good indication on weathering conditions in the region. In
particular, the highest concentration of REEs is measured for the same
sample showing the highest concentration of natural radionuclides.
Therefore, this area is investigated for the gamma dose rates by direct
measurements using identiFINDER® 2, a handheld instrument. Results indicate
layered deposits of showing relatively higher dose rates and confirming the
presence of heavy minerals. However, it is required to obtain further
information about geology and geochemistry of this area for investigating
the mineralogy and origin of these deposits.
