Determination of radioactivity levels for sea water, sediment and some macroalgae in Black Sea coast

In this work, radioactivity levels have been measured for sea water, sediment and some macroalgaes in Black Sea Coast. Also heavy metal analysis carried out for these samples. Maximum values of 238U, 232Th, 137Cs and 40K activity was foud for sea water samples, 0,025 Bq/L, 0,027 Bq/L, 0,012 mBq/L ve 2,9 Bq/L, respectaculary. Maximum values of 226Ra, 238U, 232Th, 137Cs ve 40K activity was found for sediment samples, 35,6 Bq/kg, 44,1 Bq/kg, 35,3 Bq/kg, 29,1 Bq/kg, respectaculary. Maximum values of 946,0 Bq/kg, 226Ra, 238U, 232Th, 137Cs ve 40K activity was found for macroalgae samples, 111,7 Bq/kg, 43,3 Bq/kg, 39,2 Bq/kg, 4,9 Bq/kg ve 2003,0 Bq/kg, respectaculary. Amount of Cr, Mn, Fe, Cu, Zn, Cd, Pb, Co ve Ni in sea water, sediment and macroalgae have been measured by heavy metal analysis. Relation between all measured data with samples have been compared with Kruskal Wallis and One Way Anova Statistics.
