Neutron cross-section — The total neutron cross section of an isotope of a chemical element is the effective cross sectional area that an atom of that isotope presents to neutron scattering and absorption. cattering versus absorptionWhen a neutron approaches an atomic… … Wikipedia
Neutron poison — For information on biological effects of excessive ionizing radiation, see radiation poisoning. A neutron poison (also called a neutron absorber or a nuclear poison ) is a substance with a large neutron absorption cross section in applications,… … Wikipedia
Neutron Capture Therapy of Cancer — Neutron Capture Therapy (NCT) is a noninvasive therapeutic modality for treating locally invasive malignant tumors such as primary brain tumors and recurrent head and neck cancer. It is a two step procedure: first, the patient is injected with a… … Wikipedia

Neutron detection — is the effective detection of neutrons entering a well positioned detector. There are two key aspects to effective neutron detection: hardware and software. Detection hardware refers to the kind of neutron detector used (the most common today is… … Wikipedia
Neutron radiation — is a kind of ionizing radiation which consists of free neutrons. A result of nuclear fission or nuclear fusion, it consists of the release of free neutrons from atoms, and these free neutrons react with nuclei of other atoms to form new isotopes … Wikipedia
Neutron transport — is the study of the motions and interactions of neutrons with materials. Nuclear scientists and engineers often need to know where neutrons are in an apparatus, what direction they are going, and how quickly they are moving. It is commonly used… … Wikipedia
