Fissile: meaning, definitions and examples

Etymology

• The word originates from the Latin word 'fissilis', meaning 'capable of being split'.
• It was first used in the early 20th century, particularly in the context of nuclear physics.

Science

• Fissile materials are critical in nuclear reactions, particularly for creating nuclear energy or weapons.
• Common fissile elements include uranium-235 and plutonium-239, both of which can sustain a chain reaction.
• In a nuclear reactor, controlled fission of these materials generates heat, which is converted into electricity.

Safety and Regulation

• Fissile materials are heavily regulated due to their potential for use in nuclear weapons.
• International treaties, like the Treaty on the Non-Proliferation of Nuclear Weapons, govern the use and distribution of fissile materials.

Pop Culture

• Fissile materials and their implications have featured in various films and books, often highlighting the ethical dilemmas of nuclear power.
• The term has been referenced frequently in discussions about energy crises and nuclear disasters in media.

Historical Context

• The discovery of nuclear fission in 1938 was pivotal, leading to the development of nuclear power and weaponry.
• The Manhattan Project during World War II focused on creating a bomb using fissile materials, drastically changing global politics.
