Knowra Neutron radiation Neutron radiation Neutron radiation consists of free neutrons moving through matter. It can penetrate deeply, interact with atomic nuclei, and induce radioactivity in some materials.
Neutron cross section : A measure of the probability that a neutron will undergo a specified interaction with a nucleus. Cross sections determine how likely scattering, capture, or other nuclear reactions are.
Nuclear reactor : A system that sustains a controlled nuclear fission chain reaction to produce heat or other useful outputs. Reactor cores produce neutron fields that drive fission and isotope production.
Neutron : A neutral subatomic particle found in atomic nuclei and, when free, unstable outside them. Free neutrons are the particles that constitute this radiation.
Gamma ray : A high-energy photon emitted in nuclear transitions or other energetic processes. Gamma rays interact chiefly with electrons and nuclei, unlike neutral neutrons, which can trigger nuclear reactions.
Neutron dosimetry : The measurement and assessment of absorbed dose or radiation risk from neutron exposure. Neutron dose assessment must account for energy-dependent interactions and biological effectiveness.
Neutron moderation : The reduction of neutron energy through collisions, especially with light nuclei. Moderation changes neutron energies and often increases the chance of nuclear capture.
Neutron scattering : A family of techniques that uses neutron interactions to investigate material structure and dynamics. Researchers exploit neutron penetration and nuclear and magnetic interactions to probe materials.
Ionizing radiation : Radiation energetic enough to remove electrons from atoms or molecules. Neutron radiation belongs to this broad category, though it ionizes matter indirectly.
X-ray : A high-energy electromagnetic photon produced by electron interactions or energetic transitions. X-rays and neutrons penetrate and interact differently, shaping shielding and imaging choices.
Neutron shielding : Materials and structures used to reduce neutron exposure through scattering, absorption, or both. Effective protection often slows neutrons before absorbing them.
