The
Hiroshima atomic bomb caused a nuclear fission chain reaction by
colliding neutron with uranium 235 within a barrel type when the
critical amount was exceeded. At the moment of the nuclear fission chain
reaction of one-millionth per a second, super-nuclear explosion energy
was released by about 700 g within about 50 kg of uranium 235. Ultra
high temperature of several million degrees, hundreds thousands of
atmospheric pressure, gamma ray, electromagnetic wave, neutron diffused
terrifically from the atomic bomb. While colliding with the surrounding
atmosphere they erupted while bursting hot rays and shock waves. The
energy of fission approximately composed of 5% initial radiation, 30%
heat rays, 50% blast winds, and 10% violating residual radiation.
The
phenomenon had been taken with ultrahigh speed camera at the first
Trinity experiment in human history. 1) At 1 millionth per a second, the
shock wave had bursted from the explosion point of the fireball by the
atomic bomb. 2) At 2 millionth per a second, the shock waves had
diffused concentrically from the earth's surface. 3) The blast had
rolled up the desert. From
this process, the atomic bomb had exploded at one millionth per a
second and a fireball appeared, and the surroundings emitted pale
fireball from explosion, heat ray, and radiation.
