Abstract

Seawater is a solution of compounds consisting mainly of oxygen and hydrogen (96.5 %). Eleven elements with concentrations of more than 1 mg / liter (Cl, Na, Mg, S, Ca, K, Br, C, Sr, B, F) dominate in the salt composition of seawater (99.98 %) (Vernadsky 1926; Vinogradov 1967). The natural radioactivity of seawater is dominated by the radionuclide 40K. The contribution of other radionuclides (e.g. 232U, 226Ra and others) is small, totaling about 1 % of the 40K content.
