Forbe documented the presence of cesium from Fukushima sources in Vermont here:

The distance between Vermont and Japan is 6,528 mi.
There’s no report of a giant fish kill in Vermont. Undoubtedly the radiation from Fukushima spread far and wide. But radiation is detectable at very low levels. I was just saying that the claim that radioactivity floated around in the ocean (being diluted) for 5 years and suddenly came ashore at such a strength to kill lots of fish, when no such thing had happened much closer in time and distance, doesn’t make any sense.
