Definition

Noun: A nuclear weapon designed to produce minimal residual radioactive fallout upon detonation. The term emphasizes the weapon's reduced long-term environmental contamination compared to conventional nuclear bombs.

Examples

• The military strategist discussed the theoretical advantages of a clean bomb in a tactical scenario.
• The article questioned whether a truly clean bomb was scientifically possible.
• The concept of a clean bomb was part of Cold War-era research into more "usable" nuclear weapons.

Advanced Usage

• The term is often used in theoretical, historical, or speculative contexts regarding nuclear weapons development, rather than describing a currently deployed weapon type.
• It can carry an ironic or critical connotation, as critics argue the term "clean" is a misleading euphemism for any nuclear weapon.

Variants and Related Words

• Neutron bomb: A specific type of enhanced radiation weapon sometimes colloquially referred to as a "clean" bomb, designed to maximize immediate radiation effects while minimizing blast damage and residual fallout.

Synonyms

• Low-fallout nuclear weapon
• Enhanced radiation weapon (in specific contexts)

Notes on Meaning

The term "clean bomb" refers specifically to the property of the bomb (leaving little contamination). It is not a general term for any non-nuclear explosive device that is "clean" (e.g., one that does not use toxic chemicals). Its meaning is intrinsically linked to nuclear fission or fusion weapons.

Noun

1. an atom bomb leaving little or no radioactive contamination
