Summary:Strontium 90, cesium 137, and plutonium 239 and 240 concentration surface water time series in the Pacific and Indian Oceans were analyzed under the IAEA Worldwide Marine Radioactivity Studies. The oceans were divided into 17 latitudinal boxes as a function of global fallout patterns, ocean circulation, and location of nuclear weapons test sites. Current levels and time trends in radioactivity in surface water for each box were examined. The estimated average super(90)Sr, super(137)Cs, and super(239,240)Pu concentrations in surface waters were in the 0.1-1.5 mBq/l, 0.1-2.8 mBq/l, and 0.1-5.2 mu Bq/l ranges, respectively, for 2000.
