Project 4.1
In 1994, a 1953 "Castle Bravo" program prospectus was found which included reference to Project 4.1 apparently written before the "Bravo" shot had occurred. The U.S. government responded that someone had gone back into the project list after the "Bravo" test to insert Project 4.1; thus, according to the U.S. government, the acts were not premeditated. All other U.S. documents point to Project 4.1 having been established after the "Bravo" test—most sources point to its having been organized on March 7, 1954. The final Project 4.1 report began in its preface with the statement that "Operation CASTLE did not include a biomedical program" (it mentions this in discussing the ad hoc nature by which the project personnel were assembled). All official and mainstream historical accounts of the "Bravo" test indicate that its high level of fallout was a result of a miscalculation in relation to its design and was not deliberate (see the Castle Bravo article for more information on the alleged accident).
Lijon Eknilang
Eknilang traveled extensively throughout the United States and Europe to draw attention to the health problems experienced by Rongelap's residents due to Castle Bravo. She has been called an "icon in the Marshall Islands for her international advocacy on behalf of nuclear test victims." Eknilang spoke on behalf of the former residents of Rongelap before the United States Congress. She also spoke before the Advisory Proceedings on the Legality of the Threat or Use of Nuclear Weapons at the International Court of Justice in The Hague in November 1995.
