Using complete sentences, investigate the effects of nuclear testing on the pacific islands. consider which countries tested weapons, the long-term results, and what changes resulted from the south pacific nuclear free zone agreement.

The first hydrogen bomb, named code Mike, was tested on the Enewetak atoll in the Marshall Islands, on November 1, 1952, also by the United States. The most powerful nuclear detonation in history was made by the Soviet Union: the "Czar's Bomb", or "Tsar Bomba", with a yield of approximately 50 Mt.

On August 5, 1963, a treaty was signed to limit the amount of nuclear tests. The treaty allowed only underground tests, although atmospheric detonations continued. France continued its atmospheric nuclear tests until 1974, while China continued until 1980. The last nuclear detonation carried out by the United States (underground) took place in 1992.

As a consequence I can say: In general, the radioactive fallout has not caused serious consequences to humans, except for the bombs dropped on Hiroshima and Nagasaki and the Castle Bravo test. After these two nuclear attacks, two detonations were carried out during Operation Crossroads (where about 20% of the nuclear weapons arsenal of the time was used) that took place in the Bikini Atoll. The United States made a total of six detonations before the Soviet Union detonated its first nuclear bomb, Joe-1, on August 29, 1949. The radiation also affected inhabited islands, where, although the population was evacuated, it was recorded a long exposure to radioactive fallout, and possibly over time increased cancer cases in the inhabitants of this area of ​​the Pacific.

The Treaty of Rarotonga (whose official name is the Treaty of the South Pacific as a Nuclear-Weapon-Free Zone) is an international agreement that prohibits the use, testing and possession of nuclear weapons within the geographical limits of this zone.1 Geographical area , recognized by the UN General Assembly, declared free of nuclear weapons by agreement of several states. These states agree on the total absence of nuclear weapons and the establishment of a control and verification system to guarantee compliance.
