Neutron radiation

Neutron radiation is a form of radiation that consists of free neutrons. This type of radiation is highly penetrating and can be hazardous to living organisms. It is produced in nuclear reactions, high-energy reactions of cosmic radiation with the atmosphere, and by accelerators.

Production

Neutron radiation is produced in nuclear reactions, such as those that occur in nuclear reactors and nuclear bombs. In a nuclear reactor, neutrons are produced by the fission of heavy elements such as uranium or plutonium. In a nuclear bomb, neutrons are produced by the fusion of light elements such as deuterium and tritium.

Properties

Neutron radiation is highly penetrating and can travel great distances in air. It can also penetrate most materials, including metals and concrete. This makes it difficult to shield against. Neutron radiation can also ionize atoms indirectly, through a process called neutron scattering.

Biological effects

Neutron radiation can be highly damaging to living tissue. It can cause radiation sickness, genetic mutations, and cancer. The severity of these effects depends on the dose of radiation received and the duration of exposure.

Protection

Protection against neutron radiation involves shielding and distance. Shielding materials that are rich in hydrogen, such as water and concrete, are effective at absorbing neutrons. Increasing the distance from the source of radiation also reduces the dose of radiation received.
