NEUTRON EMISSION Meaning and
Definition
-
Neutron emission is a nuclear phenomenon in which a nucleus emits one or more neutrons. Neutrons are subatomic particles with no electric charge, and they exist in the atomic nucleus along with protons. Neutron emission can occur spontaneously in radioactive elements during radioactive decay, such as in certain isotopes of uranium, plutonium, and radium.
During neutron emission, a nucleus undergoes a transformation, resulting in the release of one or more neutrons. This process often happens when a nucleus becomes unstable due to excess neutrons or protons. The emission of a neutron reduces the number of particles in the nucleus and helps it achieve a more stable state. Neutron emission can lead to the formation of a different isotope of the same element or even a completely different element altogether.
Neutron emission is a significant process in the field of nuclear physics and has various applications. It is utilized in nuclear reactors for the controlled release of neutrons as part of the fission process to sustain a chain reaction. Neutron emission is also exploited in medical treatments, particularly in neutron therapy, where neutron beams are used to treat certain types of cancers.
While neutron emission has valuable applications, it can also create potential hazards. Neutrons are highly penetrative and can damage living cells, leading to radiation sickness and other health risks. Therefore, appropriate safety measures and shielding techniques are necessary when dealing with neutron-emitting sources or radiation.
Etymology of NEUTRON EMISSION
The word "neutron" originated from the Latin word "neutron", which means "neutral". "Neutron" was coined by Sir James Chadwick in 1932 when he discovered the particle.
The word "emission" comes from the Latin word "emissus", the past participle of "emittere", which means "send out" or "release". "Emission" refers to the act of emitting or releasing something.
Therefore, when combined, "neutron emission" refers to the release or emission of neutrons, often occurring during nuclear reactions or radioactive decay.
