第五福竜丸
The fallout from the March 1954 "Bravo" test in the Pacific Ocean had "scientific, political and social implications that have continued for more than 40 years". The multi-megaton test caused fallout to occur on the islands of the Rongerik and Rongelap atolls, and a Japanese fishing boat known as the "Daigo Fukuryū Maru" (Lucky Dragon). Prior to this test, there was "insufficient" appreciation of the dangers of fallout.
