High readings compared to what? You can find radiation almost any where you look...just because you can detect something, does not make it a high radiation level.

And again, anything that would be blown up to the jet stream and across the ocean, thousands of miles, would be so dispersed as to represent virtually no risk of significant exposure downstream.

It is from a radiation network that has been monitoring for many months. They know what false readings are. They have had them in the past. This one looks legit, which is why the POTR blog released the alert.
