I read that it takes about trash from Japan takes about a year to get into the garbage patch (it didn't state exactly which one of the 5, but I'd assume the 'eastern' one which is somewhat ironically in the western pacific.) So I'd say more than likely we would see at least some of it caught up in there.

I'm curious if anyone's taken a Geiger counter out that way.

Thank you, it's much appreciated!

What scientist goes anywhere with out their handy pocket Geiger counter?
