Fukushima nuclear pollution more concentrated as it approaches U.S. West Coast

The "Science China" (anyone know if it's a reputable journal?) article that this article uses as its primary source[1] is behind a fairly expensive pay wall, but based on the abstract I think it's pretty clear that this effect is not alarming at all.

I'm sort of confused by the language but it sounds like they are saying that some small fraction (1%?) of radioactive Cesium will be reaching the coastline of the US in greater concentrations at first and then lesser concentrations.

No where, I think (but I'm not super clear on it - read for yourself!), does the abstract indicate that the concentration of Cesium reaching the US will be environmentally damaging. My guess is that we'll be talking about very small trace amounts of Cesium emitting nearly undetectable amounts of radiation.

But I am not a nuclear physicist or any other related sort of scientist!

I keep hearing this rumor, and while IANAE, I'm pretty sure the pacific current doesn't just go straight east to west... http://en.wikipedia.org/wiki/File:Corrientes-oceanicas.gif
