There are about 5 factors of destruction and destruction of nuclear weapons
1. Optical Radiation: The light and heat radiated by the flash and fireball during nuclear explosions
2. Shockwave: Nuclear The high-velocity, high-pressure air wave generated by the explosion;
3. Early nuclear radiation: gamma rays and nuclear electromagnetic radiation; impulse: The instantaneous electric field generated during the nuclear explosion is emitted outward. High intensity electromagnetic signals;
5. Radioactive Contamination: Radioactive materials produced by nuclear explosions contaminate soil, water, air, and various types of pollution.
Radioactive pollution will therefore be serious. Pollution of the sea near the explosion point! But judging by the nuclear leaks from Hiroshima and Russia. Nature is quite capable of repairing it.
