Do we need to change how we recount the Lucky Dragon incident?

In “Beyond the Lucky Dragon,” Linda M. Richards and I make the case that we need to tell the story of thermonuclear testing a bit differently than in the past. The essay focuses on the influence of Japanese scientists upon a few key Americans in the aftermath of the 1954 Bravo shot (an American hydrogen bomb test), which famously blanketed a Japanese fishing boat (the Lucky Dragon) with radioactive dust.  The premise of the essay is that focusing narrowly on the victims on the boat, while important, actually removes several important voices from story — including Japanese scientists who made claims about contamination over time and space, and who questioned anyone’s right to expose others.

Writing this essay was the first time I have collaborated with another author, and the process was a fascinating journey of mutual influences.  In addition, Linda and I circulated drafts via email among our Japanese colleagues who were writing on closely-related subjects (the essay is part of a special issue on radiation studies and Japanese scientists in the 1950s, and it appeared in Historia Scientiarum, the premier history of science Journal in Japan). I learned a tremendous amount, and was especially grateful for the opportunity to work with Masakatsu Yamazaki, Hiroshi Ichikawa, and Toshihiro Higuchi!

Abstract: In the history of the 1950s fallout controversy, associated with the first hydrogen bomb tests, scholars often focus on the plight of the Japanese crew of the Fukuryū Maru, or as it was called in English-language newspapers, the Lucky Dragon. Doing so silences the Japanese who tried to show that fallout was not simply about one ship, one part of the ocean, or even one generation of humans. In this essay we show how Japanese perspectives influenced several American scientists to think differently about the implications of nuclear tests for humans and the natural environment. We propose three fundamental conceptual points about fallout that already were present in Japanese scientific discourse in the mid-1950s. One was spatial; one was temporal; one was legal. The Japanese ideas, from a range of scientists, informed the views of American scientists during the fallout controversy of the 1950s, not just providing data but shaping both scientific and political discourse in the West.
