It may be correlation but not causation, but it is interesting to mention and think about. Could the ever ongoing Fukushima nightmare in Japan be worse than people think? The short answer: yes. But is the face 92% of Japanese having health programs in 2011 proof of that? I don't know.. It seems that the Fukushima Diary website is reporting it as though there is a connection, and we can only assume that there could be, but without proof I dare say we just don't know at this point.
We do know, however, that a pile of radiated wreckage is on a path to hit Hawaii and the West Coast. We also know that tuna and shrimp, along with other sea creatures, have been found with high levels of radiation. And we also know that butterflies have experienced mutations in the third generations in Japan.
So if 92% of people in Japan have health problems but the number was lower in the past? I can make an assumption that there is a connection. But assumptions do what assumptions do.. So I will not jump to that assumption yet.
