Denise, you seem to have been successfully fed the hysterical line regarding Fukushima that I'm afraid almost all western mass media has been peddling since the earthquake.
The fact is that tens of thousands of people have been killed, more than half a million rendered homeless as entire towns were annihilated, and yet what do our media drone endlessly on and on about?- an awful mess at a nuclear power plant which has survived one of the most severe earthquakes ever recorded and being hit by a 10 metre high tidal wave and which, at worst, is going to be very expensive for the power company to clean up and a an inconvenience to those nearby. The sheer level of pig ignorance about radiation being spouted by the majority of our media is as disgusting (for ignoring the real problems and suffering) as it is absurd (for in many cases being just a pack of lies mixed with deliberate misinformation).
Just about the only succinct rational article about the whole situation I have found is
HERE. If you make a real effort and search for scientific blogs you will find much more detail, but all along the same lines. Chernobyl this isn't, and couldn't be.
If you really are scared of the level of radiation around Fukushima, I strongly advise you steer clear of the banana display in your supermarket. You will then know why nuclear engineers refer to the BED - Banana Equivalent Dose - of radioactivity. As for taking a flight anywhere, that's tantamount to suicide, apparently.
