Perhaps it's a language barrier, but this comment makes no sense. The low-tech robots you speak of were uniformly useless, and the people working on the initial cleanup and containment were sent on what were essentially suicide missions. Information is easy to find; just google for stories about the Chernobyl liquidators.

Regarding the radiation, I think you've fallen victim to ignorance of basic facts about the nature of radiation and the oceans. Pretty much anywhere in the Pacific, radiation from Fukushima quickly dropped far below environmental background levels [1].

Here's a good quote from the source above: "The highest levels of cesium (10 Bq/m3) attributable to Fukushima that we have measured were found 1,500 miles north of Hawaii. Swimming every day in the ocean there would still result in a dose 1,000 time smaller than the radiation we receive with a single dental x-ray."
