Nuclear Weapons

How the principles of nuclear physics have been used to unleash massive destruction. How do fission bombs and thermonuclear bombs work, and what are the differences between the two? Physics - Energy And Radioactivity - Learning Points. The fission/atomic bomb was developed in the 1940s. Fission bombs use radioactive elements, such as uranium or plutonium. Thermonuclear/hydrogen bombs produce a devastating amount of energy from fission chain reactions and nuclear fusion. Nuclear bombs cause instant death and poisoning, as well as long-term hazards.
