Majuro, March 1,

Fifty years after the United States tested its biggest-ever hydrogen bomb at Bikini Atoll, flags flew at half-mast here today in honor of national Nuclear Survivors Remembrance Day.

As the legacy of the radioactive fallout spewed out by the Bravo bomb across the Marshall Islands continues, President Kessai Note and representatives of nuclear-affected islands repeatedly called on the United States to meet its responsibility to the survivors.Bikini itself can now be visited for limited periods of time but its food crops still cannot be eaten as they remain tainted by radioactivity. "For our people, for the Marshall Islands, March 1, 1954 is the defining moment in world history," said Rongelap Island Mayor James Matayoshi, whose atoll was engulfed in a blizzard of fallout following Bravo.
