Blaming the theory of LNT on poor Fukushima emergency planning is like creationists blaming the theory of evolution on Hitler's holocaust. I tried to comment there, but I have been religiously excommunicated!
The International Atomic Energy Agency didn't blame science on the failings of Fukushima, they blamed a lack of preparedness and training.
UPDATE: The IAEA link appears to be broken. Here is a similar report from the pro-nuclear power Institute of Nuclear Power Operations (INPO). See the bottom of page 4 (using the page numbering of the document, not Adobe). They didn't blame science. Obviously.
