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

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

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

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...

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...

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:...

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

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...

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...

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