need expert on nuclear fallout to interview

[Liberty Belle]

With 3 core meltdowns occurring in Japan, what are the odds of a cloud of radiation that could reach Hawaii, the west coast of the US, China, etc? How long would it take? Could it already be on the way? Could it cause deaths, cancer, radiation poisoning this far away?

Should anyone outside of Japan be trying to get hold of iodine--and by the way where do you get it?

Journalist wants to know. Please state credentials and pm me besides whatever you post here, if you have expertise and are available for an interview. Thanks.
