http://www.remappingdebate.org/article/will-there-be-risks-us-travelers-flying-domestically-wake-japans-nuclear-disaster-anyone-assWill there be risks to U.S. travelers flying domestically in wake of Japan's nuclear disaster? Is anyone assessing?
One might imagine that U.S. government agencies are well-versed in the physics of how, when, over what period of time, and with what consequences, radioactive particles may rise to the altitude of the jet stream, there to be transported from Japanese air space across the Pacific Ocean until some subset of those particles were circulating in the jet stream over the United States.
One might also imagine that a basic level of national security vigilance would mean that these agencies had definitive plans in place to coordinate with one another, apply established standards of radiological safety to the context of air travel in and through that jet stream, and update the public accordingly.
At least in respect to the second set of imaginings, it appears that one would be wrong.

After reflecting on the prospect of frequent travel over the next several weeks, the flight attendant had one more question for the government: are there "any contingency plans" if radioactive materials are found in the jet stream?
