From Thermonuclear Tests at Bikini Atoll to the Movement to Ban Nuclear Bombs In 1954, an atmospheric nuclear test on Bikini Atoll in the Pacific dispersed nuclear fallout that reached the Japanese crew of a tuna-fishing boat, the Fifth Fukuryu Maru. The consequent radiation sickness of crew members was widely reported, including the death of Aikichi Kubohama, the radio officer. This event energized campaigns to ban nuclear weapons, including a petition in Japan that gathered more than 30 million signatures.
