About 19 percent of airborne fallout from the Fukushima nuclear
disaster was deposited in Japan, and only about 2 percent made it to
other land areas in Asia and North America, according to a study
published this week by the European Geosciences Union. The bulk was
absorbed by the Pacific Ocean.

China has reported that the radioactive contamination in the Pacific Ocean from the Fukushima nuclear power plant is far wider than the areas released by the Japanese government.
China has discovered 100,000 square miles of Pacific Ocean waters, at distances up to 800 kilometers from Fukushima, with Cesium radiation levels up to 300 times normal and Strontium radiation levels up to 100 times normal.

6/25/2011 Radiation measured in the waters and air (Fukushima Plant)

In the event the seawater contains more than two nuclides, the density of each nuclide is scaled against its allowable limit. Thereafter the sum of the scaled densities of all nuclides is gauged against 1.
Let's assume the scaled density of I-131 is 0.20 times the limit and that of Cs-134 is 0.70 times the limit and that of Cs-137 is 0.60 times the limit, for example. In this case, the sum of the scaled densities of I-131 and Cs-134 and Cs-137 becomes 1.50 times the limit. This means the radioactive material in the seawater exceeds the allowable limit.
