Rongelap Atoll

1946: United States Navy evacuates Bikini Atoll Islanders prior to nuclear weapons tests.

March 1, 1954: United States detonates 15-megaton hydrogen bomb (Castle Bravo test) allegedly unaware that fallout will reach Rongelap.[7]

March 3, 1954: US evacuates Rongelap inhabitants to Kwajalein Atoll. Islanders have vomiting, diarrhea, skin burns, and some later experience hair loss. They were suffering from acute radiation syndrome.

1955-1957: Internally displaced Rongelapese inhabitants repeatedly request permission from the US Government to return to their atoll.

1957: Atomic Energy Commission declares Rongelap safe for re-habitation. US scientists note: "The habitation of these people on the island will afford most valuable ecological radiation data on human beings."[8]

1958: Rates of Rongelap miscarriages and stillbirths twice the rate of unexposed women.[9]

1963: First thyroid tumors begin to appear.

1971: Independent Japanese medical team invited by Rongelap magistrate denied permission to visit by US citing "visa problems."

1976: Report finds 69% of Rongelap children who were under 10 in 1954 have developed thyroid tumors.

1984: Marshall Islands senator Jeton Anjain requests evacuation assistance from Greenpeace because the US denies the senator's requests for evacuation.

1985: Rainbow Warrior makes three trips to evacuate the Rongelap community to Majetto and Ebeye islands in Kwajalein Atoll.

1986: Nuclear test compensation approved, setting aside a $US150 million trust fund.

1989: United States Department of Energy determines Rongelap safe for habitation.

1994: Independent scientific study finds that depending on dietary restrictions, 25 to 75% of Rongelap population would exceed the 100 mrem maximum annual exposure limit set.

2000: Marshall Islands government submits Change of Circumstances petition asking for significantly more compensation than the $US150m.

2005: Bush Administration determines it has no legal responsibility to provide additional nuclear test compensation.

2007: The Nuclear Claims Tribunal awards Rongelap more than $1 billion as fair damages for its land damage claim, however, since the $US150m trust fund is almost completely depleted this compensation can never be paid.

2012: United States government (Barack Obama administration) reasserts its position that it has satisfactorily compensated Rongelap victims.[10]

From 1946 through 1958 the United States military conducted numerous atmospheric nuclear weapons tests, including hydrogen bomb tests, primarily at Bikini Atoll, about 120 kilometers (75 mi) from Rongelap Atoll. On March 1, 1954, the testing of the Castle Bravo hydrogen device produced an explosion that was 2½ times more powerful than predicted, and produced unexpected amounts of fallout[11] that resulted in widespread radioactive contamination.[12][13][14] The blast cloud contaminated more than 7,000 square miles (18,000 km²) of the surrounding Pacific Ocean including some of the then inhabited surrounding islands including Rongerik Atoll, Rongelap Atoll (120 kilometers (75 mi) away) and Utirik Atoll.[15]

Irradiated debris fell up to 2 centimeters (0.79 in) deep over the island. A United States military medical team visited the island with geiger counters the day after the fallout, but left without telling the islanders of the danger they had been exposed to.[16] Virtually all the inhabitants experienced severe radiation sickness, including itchiness, sore skin, vomiting, diarrhea, and fatigue. Their symptoms also included burning eyes and swelling of the neck, arms, and legs.[17] The inhabitants were forced to abandon the islands, leaving all their belongings, three days after the test. They were relocated to Kwajalein for medical treatment.[17][18] Six days after the Castle Bravo test, the U.S government set up a secret project to study the medical effects of the weapon on the residents of the Marshall Islands.[19]

The United States was subsequently accused of having used the inhabitants in medical research (without receiving consent) to study the effects of nuclear exposure.[16] Until that time, the United States Atomic Energy Commission had given little thought to the potential impact of widespread fallout contamination and health and ecological impacts beyond the formally designated boundary of the test site.

In 1957, three years later, the United States government declared the area 'clean and safe' and allowed the islanders to return,[20] though they were told to stick to canned foods and avoid the northern islets of the atoll.[16] Evidence of continued contamination mounted, however, as many residents developed thyroid-tumors,[16][17] and many children died of leukemia.[17] The magistrate of Rongelap, John Anjain, whose own son died of leukemia, appealed for international help, without significant response.

In 1984, Marshall Islands senator, Jeton Anjain approached the environmental group Greenpeace to seek their help in relocating the people of Rongelap and in 1985, 'Operation Exodus' took place. In three trips, the Rainbow Warrior moved approximately 350 people and 100 metric tons (98 long tons; 110 short tons) of building material.[16] to the islets of Mejato and Ebeye on Kwajalein atoll, approximately 180 kilometers (110 mi) away. The operation took 11 days, moving everyone from 80-year-olds to newborns, as well as their homes and belongings. Ebeye is significantly smaller than the islands of Rongelap, and joblessness, suicide, and overcrowding have proven to be problems following the resettlement.

In September 1996, the United States Department of the Interior signed a $45 million resettlement agreement with the islanders, stipulating that the islanders themselves will scrape off a few inches of Rongelap's still contaminated surface. However, this is an operation deemed impossible by some critics. In recent years, James Matayoshi, the mayor of Rongelap, claimed that the cleanup was successful and envisioned a new promising future for the inhabitants and for tourists.[21] Scientific measurements made in August 2014 verified a safe level of radiation on Rongelap.[22]

In 1991, the People of Rongelap and Jeton Anjain received the Right Livelihood Award "for their steadfast struggle against United States nuclear policy in support of their right to live on an unpolluted Rongelap island."

In 2019 Chinese investor Cary Lan leased a large part of the atoll for a proposed special economic zone, in what was seen as part of ongoing efforts by China to expand its reach into the Pacific and conduct chequebook diplomacy against Taiwan.[23]

After his arrest in Thailand in 2020, the project was abandoned. He was deported to the United States in 2022 for allegedly bribing elected officials in this case. [24]
