Abstract

Both the specific activity of tritium and the concentration of several ions(Na^＋, K⁺, Mg^2＋, Ca^2＋, Cl^－, NO₃^－, SO₄^2－) in precipitation at typhoons in Niigata city, Japan were measured, and the following matters were found as to precipitation at typhoon. (1)Specific activities of tritium at typhoons were under the average of the activities in precipitation in the same month. (2)The specific activity of tritium depends on that whether the precipitation was sampled after the several days from the last rain, or not so long. (3)Movements of these ion concentrations in precipitation are similar to each other except nitrate ion. (4)Each ion concentration ratio in precipitation at a typhoon became to be similar to that in sea with time. (5)Using relative compositional ratio of sampled water to sea water defined in this research, the effect of sea water on precipitation can be revealed.
