TEPCO is pretty much confirming that it is dumping contamination into the pacific from what once nuclear reactor cores sinking into the ground below their plant. That material entering the Pacific is not a "dilution strategy" it is a thorough contamination strategy. Some daughter isotopes: cesium, iodine, strontium, "heavy hydrogen", etc... are biologically active. Some are "concentrated up the food chain" and affect top predators like ourselves more than vegetarians, and vegetarians more than the vegetables. But even tiny amounts of radioactive substances and radioactive poisons cause illness, cancer and death. And the statistics can hide the effects, but this is demonstrated science and even has it's own term "stochastic disease." Potassium iodide might help with the uptake of radioactive cesium and iodine but there are a whole host of radioactive substances coming "downwind" and downstream of fukushima that are harder to avoid. Arnie Gunderson recently noted during an interview on "Coast To Coast" at WFLA:
"Gundersen concurred on the direness of the Fukushima situation-- in contrast to Chernobyl and Three Mile Island, the "spigot" isn't turned off yet, and radiation continues to leak into the Pacific Ocean. Fish are picking up extraordinarily high levels of radioactive materials, and Gundersen said he would not eat fish that comes from the West Coast. In Japan, "the epidemiological data that will develop over the next 30 years [will show that] somewhere between 100,000 and 1 million new cancers will develop as a result of this," but the nuclear industry can hide behind the fact that a high percentage of people get cancer anyway, he pointed out. Gunderson stressed the importance of stopping the groundwater contamination, and suggested building a trench of zeolite to absorb the radiation surrounding the plant."

Enews published this picture from the Embassy of Japan illustrating the problem Gunderson alludes to:
So far there is little effort that Japan is even taking this seriously. It may be that much of the material was scattered during the explosions and fires that occurred at the beginning of this disaster and that there is not that much left to contain. Who knows? But they could at least be doing something here.
