The accident occurred when a thermonuclear device was detcnrated at Bikini in the Pacific Proving Grounds. The yield was larger than expected and since the fireball touched the ground, a large amount of incinerated coral and debris was mixed with the radioactive cleud. An unexpected shift in winds occurred high aloft and instead of the ciexd going in a northerly direction over the open sea, it veered to the est dropping radioactive fallout on several inhabited islands. The falicut exposure of the Marshallese people was different in many respects [rem the exposure of the people of Hiroshima and Nagasaki to the effects of the atom bomb detonated over Japan. in Japan the injuries were produced by direct irradiation from gamna rays and neutrons, and from physicai injuries from blasts and burns. Psychic trauma, malnourishment, and disease complicated their radiation injuries. Little or no failout vas involved. In contrast the radiation exposure of the Marshallese peopie *Research supported by the U.S. Atomic Energy Commission.
