But that is more from the water circulation than air. The reason, ejecta right now is not reaching the wind stream. We haven't had an explosion again. It did after the initial explosion and we did have a cloud of hot shit come over us, starting seven days into the incident. (Ironically that is when a bunch of Geiger counters went off line, coincidence? I don't believe in them)
Right now some particles might be rising that high, unlikely but benefit of doubt and all that...sure, minimal at best. So most of the crap reaching North America is coming with the water and high level predators, like tuna. As is, whatever is escaping in the steam hardly is reaching 30k feet, but is falling on the water, and reaching NA that way. We are in a closed system, so it's gotta go somewhere.
The longer this continues, the higher concentrations in the life systems, and the more effects on the environment. Japan will see much higher rates of cancer, and we will see just higher rates in the West Coast as well.
Due to distance the rates in NA will be lower than in Japan, but in the measurable range. The children who were playing out when the hot cloud came over will be the ones with the highest spikes just from the Chernobyl experience.
Japan was lucky that prevailing winds took most of that crap to sea, but it's rates will be much higher due to how close.
My true nightmare is if we have another explosion or two due to criticality. The steam is getting generated. TEPCO does have that from time to time, so if this becomes a daily occurrence, or we have another killer quake. I don't want to start counting the ways that could go wrong.
