NEUTRON RADIATION Meaning and
Definition
-
Neutron radiation refers to the emission of free neutrons from a radioactive source or as a result of nuclear reactions. Neutrons are subatomic particles that are electrically neutral and have a mass slightly greater than that of protons. In the context of radiation, neutron radiation can be categorized into two types: slow and fast neutrons.
Slow neutrons are typically emitted in nuclear fission reactions or during the decay of certain isotopes. They have significantly reduced kinetic energy and are more efficient in causing nuclear reactions in materials, hence their importance in nuclear reactors and nuclear weapons. Fast neutrons, on the other hand, possess greater kinetic energy and are often produced during the interaction of cosmic rays with the Earth's atmosphere.
Neutron radiation possesses unique properties that differentiate it from other forms of ionizing radiation, such as gamma rays or alpha particles. Neutrons can penetrate deeply into various materials, including dense metals, without being deflected or losing considerable energy. This ability makes them hazardous as they have the potential to damage living tissues and induce nuclear reactions in certain substances. Furthermore, they can transform stable isotopes into radioactive ones, leading to the creation of radioactive sources.
Neutron radiation is commonly measured using specialized instruments like neutron detectors or dosimeters, which quantify the number of neutrons present in a given area or the dose received by an individual. Shielding is often required to protect against neutron radiation. Common materials used for shielding include hydrogen-containing substances like water or concrete, as neutrons can interact with hydrogen nuclei through a process known as scattering.
In summary, neutron radiation refers to the emission of neutrons from radioactive sources or nuclear processes, possessing unique properties that distinguish it from other forms of radiation. Its ability to penetrate materials deeply and induce nuclear reactions makes it both a useful tool in various fields

Etymology of NEUTRON RADIATION
The word "neutron" originated from the Latin word "neutron" meaning "neuter" or "neutral". The term was first coined by Ernest Rutherford in 1921 to describe the neutral subatomic particle discovered by James Chadwick.
The word "radiation" comes from the Latin word "radiare" meaning "to emit rays or beams". It was later adopted into English and refers to the emission or transmission of energy in the form of electromagnetic waves or particles.
Therefore, the term "neutron radiation" combines the word "neutron" with "radiation" to describe the emission of neutrons, which are electrically neutral particles, often associated with nuclear reactions or radioactive decay.
