Radioactive Isotopes Expected to Reach U.S. Coast In One To Two Years Woods Hole Institute To Send Research Vessel To Japan
Oceanographers know that the Kuroshio current sweeps west from Japan to the Central Pacific and then toward the U.S. West Coast, but theyre less certain how it behaves after it branches toward Alaska and California.
Radiation still leaking into the sea from the damaged Fukushima nuclear power plant will help them document the oceans circulatory system.
By the time that current reaches the Central Pacific, there are branches heading more towards Alaska and the Souththat gets harder to predict, said Ken Buesseler, a senior scientist with the Woods Hole Oceanographic Institute.
But thats one of the things that several people hope to do by measuring these isotopes even at levels when theyre not harmful. We could actually track those ocean currents and better understand the circulation pattern in the Pacific.
Woods Hole is preparing a research cruise to study waters off of Japan, Beuesseler told me yesterday via email. His comments also derive from a recent interview on WGBH.
Scientists have predicted that Fukushimas longer living isotopessuch as cesium-137, with a half-life of 30 yearswill reach Hawaii in about a year and the coast of California in two to three years. By that time, the isotopes should be significantly diluted from mixing with ocean water.

Radioactive iodine from Fukushima is already showing up in milk in Hawai’i. That and the currents in the Pacific make about four to seven knots so any seaborne radioactive material first made it to the Pacific coast sometime last month.
This must be why the Nuclear Regulatory Commission ceased 24 monitoring saying the conditions at Fukushima have been slowly stabilizing and that they’ve had ‘continuing improvement’....
You ALMOST owed me a KEYBOARD!!!! But I needed the laugh...
“Radioactive iodine from Fukushima is already showing up in milk in Hawaii.”
Not that it is any kind of health threat, and further the concentration is cut in half every eight days...
In late April, EPA milk samples in Hawaii show radiation in milk at 800% above limits for C-134, 633% above limits for C-137 and 600% above EPA maximum for I-131 for a total of 2033%, or 20.33 times, above the federal drinking water limits. Also, I’ve read a few times now that Iodine 131 has an 8 day half-life outside the body and a 100 day half life inside the body.
Note that this comparison between milk and water uses the guidelines for water rather than milk. The FDAs Derived Intervention Level for iodine-131 in milk is 4700 picoCuries per liter. The EPAs MCL for iodine-131 is 3 picoCuries per liter.
Good article about EPA and FDA limits here: http://blogs.forbes.com/jeffmcmahon/2011/04/10/epa-new-radiation-highs-in-little-rock-milk-philadelphia-drinking-water/
This is the money quote: “Another reason for FDAs more relaxed standard is a higher tolerance for mortality.”
