This atom will then disintegrate by producing chain reactions. These reactions are not controlled, it will therefore cause an explosion. 01:45 While a nuclear fission bomb exploses, a radioactive isotope of uranium is used. It may desintegrate in one atom of iodine 131 and one of ruthenium 103 and produce two neutrons. 02:05 And some hours, or a day, after the bombing, people and animals were allowed to go out. But the lagoon was contaminated once again, fish too, coconuts too... 02:20 Thus, all the basic food of the inhabitants of the area was contaminated. 02:28 Having nothing else to eat, they ate these foods exposed to radioactivity. 02:36 Iodine 131, which results of the uranium's desintegration, penetrates into the body of the people. 02:44 The thyroid is a butterfly-shaped gland at the base of the neck. This is called an endocrine gland. It ...
