This
study is an evaluation of radioactivity the waters of the Çanakkale Strait. The
total alpha- and total beta-radioactivity counts (Berthold, LB770-PC 10-Channel
Low-Level Planchet Counter) were calculated for seawater samples taken from
eight different regions of the Çanakkale Strait (Şevketiye, Seddülbahir,
Lapseki, Kumkale, Burhanlı, Dereliman, Eceabat and Gelibolu). In the samples,
the total alpha-radiation ranged between 0.064 and 0.046 Bq/L and the total
beta-radiation ranged between 14.325 and 10.532 Bq/L. The highest total alpha-radiation
concentration was measured at Gelibolu (0.064 Bq/L) while the lowest (0.046 Bq/L)
was measured at Şevketiye. The highest value for total beta-radiation concentration
(14.325 Bq/L) was measured in Seddülbahir and the lowest value (10.532 Bq/L)
was measured in Dereliman. The total alpha-radiation concentrations measured by
the Turkish Atomic Energy Authority in Çanakkale’s drinking and utility water
ranged between 0.05 and 0.400 Bq/L, and the highest values (0.300 to 0.400 Bq/L)
were found in the Ezine county. Total beta-radiation concentrations ranged from
0.05 to 0.500 Bq/L, and the highest values (from 0.400 to 0.500 Bq/L) were recorded
in Lapseki province. The total beta-radiation concentrations in both the sample
results and TAEK data were determined to be high in Lapseki and its vicinity.
Comparing the mean total beta- and alpha-radiation concentration values of the
Çanakkale Strait with the Bosphorus, the Sea of Marmara and the Black Sea, beta-radiation
values in the study area were very high. Total alpha-radiation results were low
in the study area compared to other areas. Evaluating the results against the
legal limit threshold, the results were above the legal limit for total beta-radiation.
This result indicates that the water is affected by the rocks through which it
passes.
