Where is Bikini Atoll located?
Bikini Atoll is in the Ralik (western) chain of the Marshall Islands in the central Pacific Ocean. It is north of the Equator, 225 miles (360 km) northwest of Kwajalein Atoll and 190 miles (305 km) east of Enewetak. The atoll consists of about 20 small coral islands that average around 7 feet (2.1 meters) above low tide.

What is Bikini Atoll?
Bikini Atoll, situated in the Ralik chain of the Marshall Islands, is a ring of about 20 small coral islands. The islands surround an oval lagoon that is approximately 25 miles long and 15 miles wide.
Between 1946 and 1958, the United States used the atoll for atomic explosions. The tests caused serious radioactive contamination. The native Micronesians were relocated to other islands, including Kili Island. Although cleanup projects have occurred, radiation levels remain too high for permanent resettlement. Today, Bikini Atoll is open for tourism, including scuba diving among the sunken warships in the lagoon.

Who lives on or has lived on Bikini Atoll?
Bikini Atoll was originally inhabited by Micronesians. However, in 1946, the U.S. Navy relocated the atoll's 166 native Micronesians to Rongerik and Kili island to conduct atomic weapons testing.
Some islanders began returning to Bikini in the late 1960s, but had to be moved back to Kili in 1978 because radiation levels were too high. As of now, Bikini and Enewetak remain contaminated with radiation, making them unsafe for habitation and consumption of locally grown food.

Why is Bikini Atoll famous?
Bikini Atoll is famous because the United States used the area for peacetime atomic explosions for experimental purposes from 1946 to 1958. In 1946, the U.S. relocated Bikini's Micronesian population to other islands and conducted the worldâs first peacetime atomic-weapons test at Bikini. Over twelve years, the U.S. conducted 67 nuclear tests, including the first hydrogen bomb dropped from a U.S. airplane in 1956. The atoll suffered serious radioactive contamination from these tests, and though cleanup projects have occurred, radiation levels remain too high to allow resettlement.

What happened during the nuclear tests at Bikini Atoll?
Between 1946 and 1958, the United States conducted 67 nuclear tests at Bikini Atoll in the Marshall Islands. These tests, performed in the air, on ships, and underwater, were intended to assess the effects of atomic bombs on naval vessels and to further develop nuclear weaponry.
The first test, part of Operation Crossroads, occurred on July 1, 1946, when a 20-kiloton atomic bomb was dropped over a fleet of obsolete World War II ships. The second test was the worldâs first underwater atomic explosion, which created a column of radioactive water. The most devastating test, Castle Bravo in 1954, had a yield of 15 megatons, vaporizing three islands and spreading radioactive debris over a vast area.

How have the nuclear tests affected Bikini Atoll and its people today?
Between 1946 and 1958, the U.S. military conducted nuclear tests at Bikini Atoll, part of the Marshall Islands, resulting in serious radioactive contamination. The native Micronesians were relocated, and some returned in the late 1960s, but had to be moved again in 1978 due to dangerously high radioactivity levels.
The tests, including the devastating Castle Bravo, had far-reaching consequences, vaporizing islands and scattering radioactive debris. Neighboring atolls experienced radioactive fallout, leading to severe health problems, including radiation sickness, burns, miscarriages, stunted growth, and thyroid illnesses. Studies have identified at least 25 medical conditions in the region resulting from radiation exposure.
As of now, Bikini and Enewetak remain contaminated, making it unsafe to consume anything grown on the land or to inhabit the atolls.

Bikini, atoll in the Ralik (western) chain of the Marshall Islands in the central Pacific Ocean. The atoll was used for peacetime atomic explosions conducted for experimental purposes by the United States between 1946 and 1958.
Lying north of the Equator, Bikini is 225 miles (360 km) northwest of Kwajalein Atoll and 190 miles (305 km) east of Enewetak. It consists of a ring of about 20 small coral islands whose average elevation is only some 7 feet (2.1 metres) above low tide level. The area of the group amounts to little more than 2 square miles (5 square km) of dry land, distributed about the edges of an oval lagoon 25 miles (40 km) long and 15 miles (24 km) wide. The largest islands are Bikini and Enyu (or Eneu). The atoll was known before World War II as Escholtz Atoll. It was administered by the United States from 1947 as part of the Trust Territory of the Pacific Islands under a United Nations trusteeship until it became part of the Republic of the Marshall Islands in 1979.
After Japan had been driven from the Marshall Islands in 1944, the islands and atolls, Bikini among them, came under the administration of the U.S. Navy. In 1946 Bikini became the site of Operation Crossroads, a vast military-scientific experiment to determine the impact of atomic bombs on naval vessels. The tests made it necessary to first relocate the atollâs 166 native Micronesians to Rongerik and then to Kili island, about 500 miles (800 km) southeast of Bikini. The worldâs first peacetime atomic-weapons test was conducted at Bikini on July 1, 1946. A 20-kiloton atomic bomb was dropped from an airplane and exploded in the air over a fleet of about 80 obsolete World War II naval vessels, among them battleships and aircraft carriers, all of them unmanned. The second test, on July 25, was the worldâs first underwater atomic explosion; it raised an enormous column of radioactive water that sank nine ships. Further tests, some of them thermonuclear, were conducted from 1954 to 1958, when Bikini, together with Enewetak Atoll, constituted the Pacific Proving Ground of the United States Atomic Energy Commission. In 1956 Bikini was the test site of the first hydrogen bomb dropped by a U.S. airplane.
The atoll suffered serious radioactive contamination from these tests. In 1969 the U.S. government began work on a long-range project to reclaim the land and, ultimately, to repatriate the Bikinian population. Some native islanders began returning to Bikini in the late 1960s, but they had to be moved back to Kili in 1978 when it became clear that radioactivity levels at Bikini were still dangerously high. In 1985, in response to a lawsuit filed by Bikini islanders, the U.S. government agreed to fund a cleanup of the island chain. Work began in 1991, and the first cleanup project was completed in 1998. However, radiation levels were still considered too high to allow resettlement, although they were deemed low enough to permit tourism on the atoll. In 1996 it was opened for scuba diving among the lagoonâs sunken warships, and sport fishing began two years later.
