I've heard that the US is affected health wise for the Japan radiation...?

Question:

from a friend of mine. Is this true? And how are we affected health wise? Thank you! =)

Answer:

We are not affected yet, and it's likely that we will not be affected at all. The Chernobyl meltdown impacted people within a 300 mile radius or so. Japan is thousands of miles away. Any radiation cloud that is released will have dispersed to the point that the exposure isn't going to be dangerous.
