ON THE VARIABILITY OF RADIOACTIVE BACKGRO UND IN THE OCEAN

Variability of radioactive background in the ocean causing inconstancy of the potassium-chlorine ratio have been considered. Double-diffusiv e convection in ''diffusive'' form is examined to evaluate possible de partures from constancy of ion-chlorine ratios. The equations for diff usion of major ions of seawater over the density interface have been d eveloped. Dissipation of double-layers structure increases potassium-c hlorine ratio in the upper layer by 0.34% and by 0.79% if thermodiffus ion is taken into account and not taken into account accordingly.
