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 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
Neutron monitor — A neutron monitor is a ground based detector designed to measure the number of high energy charged particles striking the Earth s atmosphere from outer space. For historical reasons the incoming particles are called cosmic rays , but in fact they … Wikipedia
Neutron reflector — A neutron reflector is any material that reflects neutrons. This refers to elastic scattering rather than to a specular reflection. The material may be graphite, beryllium, steel, and tungsten carbide, or other materials. A neutron reflector can… … Wikipedia
