Shock wave is the overpressure of huge airflow produced after nuclear explosion. After the explosion of the 30,000-ton atomic bomb, the velocity of the shock wave can reach 200 m/s at a distance of 800 m from the explosion center. For a nuclear explosion with an equivalent of 20,000 tons, the overpressure value within 650 meters of the projection point of the explosion center is greater than 1000g/cm2. It can completely destroy all buildings and people in the area.
Early nuclear radiation is a stream of neutrons and gamma rays released in the first few seconds of a nuclear explosion. After the 1 atomic bomb with an equivalent of 20,000 tons explodes, people within the range of 1 100 meters of the explosion center can be extremely killed. /kloc-After the 0/000t neutron bomb explodes, people within this range will die within a few weeks, and people within 200 meters will die immediately.
The electric field intensity of electromagnetic pulse can reach 1 0,000 to 1 0,000 volts within several kilometers, which can not only seriously damage the components of electronic equipment, but also break down insulation, burn down circuits, cancel computer memory, and invalidate all radio command, control and communication equipment. 150 million-ton atomic bomb explosion, the damage radius can reach 190 km. Radioactive pollution is the smoke and dust falling after mushroom-shaped smoke clouds disperse, which can cause radiation or skin burns and even death to human body. 1954 On February 28th, the150,000-ton hydrogen bomb tested by the United States in Bikini Island exploded 6 hours later, and the polluted area was 257 kilometers long and 64 kilometers wide. All the creatures in this range die slowly or become disabled for life because of pollution.
