I originally wrote this post hours before my father's death in January 2009. It was followed in the Nuclear Green sequence of posts by a notice of my father's death and then by his obituary. Of all Nuclear Green posts, this is more relevant to the current situation. in Japan. I have revised it in order to focus on my father's contention that the worst case consequences of worst possible nuclear accidents are not all that bad. The relevance of the current situation in Japan should be obvious.
