Thanks for being a really decent counterweight.
As title really good to see some constructive counter argument from someone who is at least a reasonably informed person.
I do think that perhaps you are leaning a little far to the "There is absolutely no risk" category - lets face it we have had only a small handful of incidents like this so I would argue that there is still the Things We Don't Know We Don't Know. Is it possible radioactive particles are being carried through the water overflowing from the pools down into the sea for example.
What it has been great to be reminded of though is that there is absolutely no risk of massive loss of life from this incident. Japan has a disaster to recover from and loss of power production is going to be a big part of it as has been pointed out by others. The media has a lot to answer for creating the fear that their mis-informed sensationalist reporting has resulted in. Japan needs to be mourning taking stock and then cracking on with getting their country back on it's feet - not being paralyzed by fear and looking over their shoulders for a boogey man that just does not exist.
