Daigo Fukuryū Maru

Daigo Fukuryū Maru (第五福龍丸, F/V Lucky Dragon 5) was a Japanese tuna fishing boat with a crew of 23 men which was contaminated by nuclear fallout from the United States Castle Bravo thermonuclear weapon test at Bikini Atoll on March 1, 1954. The crew suffered acute radiation syndrome (ARS) for a number of weeks after the Bravo test in March. All recovered except for Kuboyama Aikichi, the boat's chief radioman, who died on September 23, 1954 from complications of radiation sickness.[1] Kuboyama is considered the first victim of the hydrogen bomb and of test shot Castle Bravo.[2]
