File:Castle Bravo fish contamination map.png

Radioactive contamination of water and fish in the western Pacific Ocean by the 1954 Castle Bravo nuclear weapon test at Bikini Atoll.

This drawing was produced in 1955 by Y. Nishiwaki for a Japanese government study and reprinted, somewhat simplified, in S. Sevitt, "The Bombs," The Lancet, July 23, 1955, pp. 199-201. It is probably public domain due to origin and age, and its author is unlikely to still be contactable. In any event, I think it qualifies for fair use because it is uniquely informative and its publication 54 years ago in The Lancet gives it authenticity.
