Atolls - Bikini Atoll
The Bikini area is famous for being (as part of the Pacific Proving Grounds) the site of more than 20 nuclear weapons tests between 1946 and 1958.
The natives were relocated in 194 and remained in exile on other islands.
Today, the islands are safe to visit, and radiation levels are now lower than they were in the past.
But the soil still contains dangerous levels of radioactive material.
The fish were not affected by the radiation, and are abundant due to the lack of fishing in this area.
Most visitors travel to the atoll to dive and search for shipwrecks from the 1946 tests.
