High radioactivity levels coming straight from Japan over the US right now.

Um...no. There's a huge difference between detectible radiation, above background radiation, and high radiation levels. Just because someone is detecting higher than normal background radiation levels does not mean they are detecting 'High' radiation levels. It is often the case at some nuc plants that radiation alarms can be set off by changes in naturally occurring background radiation from outside the plant.

BTW...heavier radioactive elements, such as U-235, from Fukushima are just that...heavy...they are too heavy to make it up to the jet stream.

Also...anything that does make it that far up into the atmosphere will be so diluted and spread apart by the time it transits the ocean so as to pose almost no significant exposure threat downstream.

Calm down...take a deep breath...far more people will die of the stress caused by over-hype than will ever die of exposure to contamination from Fukushima.

Exactly

So we should just ignore all high readings ? That would be stupid considering we have 3 completely melted reactors and 4 spent fuel pools with problems located up stream from the readings.
