Neutron radiation is a form of ionizing radiation that presents as free neutrons. Typical phenomena are nuclear fission or nuclear fusion causing the release...

A neutron bomb, officially defined as a type of enhanced radiation weapon (ERW), is a low-yield thermonuclear weapon designed to maximize lethal neutron...

particle radiation consists of particles of non-zero rest energy, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation acoustic...

newly formed neutron stars typically rotate at up to several hundred times per second. Some neutron stars emit beams of electromagnetic radiation that make...

photons always have enough energy to qualify as ionizing radiation. Neutron radiation, alpha radiation, and extremely energetic gamma (> ~20 MeV) can cause...

much neutron reflection was required to approach supercriticality. On August 21, 1945, the plutonium core produced a burst of neutron radiation that resulted...

Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming...

not stop fission neutrons produced by plutonium sources, however. As a result, radiation detectors usually combine gamma and neutron detectors, making...

the enormous amounts of radiation released, also feature on occasion. Neutronium, the degenerate matter that makes up neutron stars, often turns up as...

Neutron scattering is practiced at research reactors and spallation neutron sources that provide neutron radiation of varying intensities. Neutron diffraction...

Neutron detection is the effective detection of neutrons entering a well-positioned detector. There are two key aspects to effective neutron detection:...

disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three...

A neutron howitzer is a neutron source that emits neutrons in a single direction. It was discovered in the 1930s that alpha radiation that strikes the...

radiological warfare agents are produced through neutron capture by the salting materials of the neutron radiation emitted by the nuclear weapon. This avoids...

Neutron capture therapy (NCT) is a type of radiotherapy for treating locally invasive malignant tumors such as primary brain tumors, recurrent cancers...

The discovery of the neutron and its properties was central to the extraordinary developments in atomic physics in the first half of the 20th century...

Occasionally, when an atom of 238U is exposed to neutron radiation, its nucleus will capture a neutron, changing it to 239U. This happens more often with...

properties, neutrons and X-rays provide complementary information: X-Rays are suited for superficial analysis, strong x-rays from synchrotron radiation are suited...

A neutron source is any device that emits neutrons, irrespective of the mechanism used to produce the neutrons. Neutron sources are used in physics, engineering...

would greatly reduce problems associated with neutron radiation such as damaging ionizing radiation, neutron activation, reactor maintenance, and requirements...
