| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
An elementary particle with 0 charge and mass about equal to a proton; enters into the structure of the atomic nucleus
Classified under:
Nouns denoting natural objects (not man-made)
Hypernyms ("neutron" is a kind of...):
nucleon (a constituent (proton or neutron) of an atomic nucleus)
Context examples:
Atoms of different elements contain different numbers of protons, neutrons, and electrons.
(Atom, NCI Dictionary)
The amount of energy from any type of ionizing radiation (e.g., alpha, beta, gamma, neutrons, etc.) deposited in any medium (e.g. water, tissue, air).
(Absorbed Radiation Dose, NCI Thesaurus)
A substance used in a type of radiation therapy called boron neutron capture therapy.
(Boron phenylalanine, NCI Dictionary)
Oxygen atoms having the same atomic number (protons) but different mass numbers (and different numbers of neutrons).
(Oxygen isotopes, NOAA Paleoclimate Glossary)
The use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors.
(Irradiation, NCI Dictionary)
A type of radiation therapy that uses tiny particles called neutrons made by a machine called a cyclotron.
(Fast-neutron beam radiation, NCI Dictionary)
The neutrons react with the boron in BPA-F, producing radioactive particles that kill the tumor cells without harming normal cells.
(BPA-F, NCI Dictionary)
Dawn's gamma ray and neutron (GRaND) detector observed evidence that Ceres had accelerated electrons from the solar wind to very high energies over a period of about six days.
(Ceres' Geological Activity, Ice Revealed in New Research, NASA)
When exposed to neutron irradiation, boronophenylalanine absorbs neutrons and self-destructs releasing short-range alpha radiation and 'recoil' lithium in tumor cells, resulting in alpha radiation-induced tumor cell death.
(Boronophenylalanine-fructose complex, NCI Thesaurus)
The neutrons react with the boron in boronophenylalanine-fructose complex, producing radioactive particles that kill the tumor cells without harming normal cells.
