Fissionable Meaning: Definition, Examples, and Translations
⚛️
fissionable
[ˈfɪʃənəbl ]
Definition
nuclear reactions
Fissionable refers to a substance that is capable of undergoing fission, which is the process of splitting an atomic nucleus into two or more smaller nuclei, along with the release of energy. This property is particularly significant in the context of nuclear reactors and weapons, where fissionable materials such as uranium-235 or plutonium-239 are utilized.
Synonyms
Examples of usage

Interesting Facts
Science
- Fissionable materials, like uranium-235 and plutonium-239, are crucial in nuclear reactors and weapons.
- When a fissionable nucleus splits, it releases a significant amount of energy and additional neutrons, which can cause further fission in nearby atoms.
History
- The discovery of nuclear fission by scientists Lise Meitner and Otto Hahn in 1938 was pivotal in the development of atomic energy.
- The first successful fission chain reaction was achieved by Enrico Fermi in 1942 at the University of Chicago, marking the start of the atomic age.
Environmental Impact
- While fissionable materials can be used for energy, they also produce radioactive waste that must be managed carefully.
- Nuclear power from fissionable substances is considered by some to be a clean energy source, as it emits no greenhouse gases during operation.
Cultural Significance
- The concept of nuclear fission has influenced a vast array of literature and films, often depicted with themes of power, fear, and ethical dilemmas.
- Movies like 'The China Syndrome' and 'Dr. Strangelove' explore the political and social ramifications of nuclear energy and weapons, showing the dual nature of scientific advancements.
Origin of 'fissionable'
Main points about word origin
- The term comes from the Latin word 'fissio', meaning 'a splitting'.
- It combines with the suffix '-able,' indicating something that can be acted upon, creating a word that means 'capable of splitting.'
The term 'fissionable' is derived from the word 'fission,' which originates from the Latin term 'fissio,' meaning 'to split.' The concept of fission was first recognized in the 1930s when scientists discovered that certain heavy nuclei, such as uranium, could be induced to split into lighter nuclei when bombarded with neutrons. This discovery paved the way for both nuclear energy and atomic bombs. The adjective 'fissionable' was introduced to describe materials that possess the ability to undergo this splitting process, and it has since become a crucial term in nuclear physics and engineering. The understanding of fissionable materials has evolved over the decades, leading to the development of advanced reactors and nuclear technologies.
