Serious nuclear weapons damage human being into serious crisis from 239 plutonium type as Nagasaki atomic bomb.

　Trinity experiment using 239 plutonium same as Nagasaki atomic bomb was carried out at 5:29 am on July 16, 1945. It was burst from the zero point on the ground surface in the desert. The photograph of the fireball was taken by a super high speed camera  after 0.25 seconds after the explosion of the atomic bomb. The fireball had a diameter of about 310m at the moment. 90% of the heat rays were released from the fireball until 2 seconds. The blast  reached its maximum in about 2 seconds. A large amount of gamma ray which rapidly increases to 2 seconds was released and reacted with surrounding air to emit purple growing the mushroom gradually.

 Comparing the atomic bomb with the explosion of TNT explosion, 1) the enormous explosive power of 10 million times or more than TNT, 2) the blast with a catastrophic shock wave, 3) terrifically reaching several million degrees, 4) serious damage to the human body caused by release of radioactivity 5) Stopping the life at not only human body but also urban function by electromagnetic waves with powerful gamma rays. The atomic bomb will harm ordinary human beings into a crisis with an incomparable power on the earth.

Nagasaki Atomic Bomb was exploded by chain reactions from Plutonium 239 spherically and strongly imploded.

　　About 1200 tons of uranium ores stored in Staten Island adjacent to Manhattan in New York City were developed and manufactured for Atomic Bombs. The target of Uranium 235 contained only 0.7% of Uranium 238. A large amount of Plutonium 239 could be purified from inside the nuclear reactor with Uranium 238 absorbing the neutrons. Even though Plutonium 240 contained in Plutonium 239 spontaneously fission and releases neutrons. An atomic bomb device should be developed in which plutonium 239 could caused a nuclear fission chain reaction.

   The Plutonium type of Nagasaki atomic bomb generated neutrons from the center and were absorbed into the Plutonium 239. Furthermore, Uranium 238 mainly surrounded them, and strong bomb were scattered spherically from the outside. Plutonium 239 were strongly imploded and chain reactions of nuclear fission occurred in the central part and exploded with super- destructive energy. Implosion of Plutonium 239 were extremely difficult. It succeeded for the first time in history by the Trinity experiment on July 16, 1944.
