Scientists Will Track Fukushima Radiation To Study Ocean Currents, Forbes.com, May. 17 2011 at 8:34 am EDT:
[...] Scientists still don’t know the full content of the release that reached the ocean. The Japanese regularly test the seawater only for Iodine-131 and for two isotopes of cesium.
They have not tested for other radioactive isotopes that interest oceanographers, such as tritium and strontium, which was detected in Hawaii. Tokyo Electric Power Company conducted one seawater test for plutonium, which had been found in soil around the plant, and reported it non-detectable.
Scientists from the International Atomic Energy Agency are also interested in learning more about releases of Technetium-99, which has a half life of 210,000 years, and Iodine-129, which has a half life of 14 million years. The Japanese have released no information about those isotopes. [...]
