There were radiation tests done on other islands after the WWII. Don't know where though. A neighbour from years ago was part of it. He died from leukemia in his 50's.
There is also a conspiracy that the Tsunami near there in 2004, was artificially created by a 'Tsunami Bomb'.
Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together. All things connect.
