Even more troubling.. There's a similar generation nuclear reactor about 40 miles from NYC. Just imagine the cost if Manhattan was in an exclusion zone.
There are areas over 100km away that are still in the closed zone. They found hotspots of >100 curies/sq km up to 300km from the reactors. It's not like there's a safe little 30km concentric circle.
If NYC were upwind from Indian Point, I woudln't be "fear-mongering" but an event like Chernobyl would very likely impact NYC.
