thermal neutron porosity measurement

Oil & gas; Oilfield

A measurement of the slowing down and capture of neutrons between a source and one or more thermal neutron detectors. The neutron source emits high-energy neutrons that are slowed ...

thermal neutron absorber

Oil & gas; Oilfield

neutron

Weather; Meteorology

An uncharged subatomic particle. The rest mass of the neutron is slightly greater than that of the proton. Atomic nuclei are composed of protons and neutrons bound together by ...

alpha particle

Energy; Nuclear energy

A positively charged particle ejected spontaneously from the nuclei of some radioactive elements. It is identical to a helium nucleus that has a mass number of 4 and an ...

attenuation

Energy; Nuclear energy

The process by which the number of particles or photons entering a body of matter is reduced by absorption and scattered radiation.

binding energy

Energy; Nuclear energy

The minimum energy required to separate the nucleus of an atom into its component neutrons and protons.

chain reaction

Energy; Nuclear energy

A reaction that initiates its own repetition. In a fission chain reaction, a fissionable nucleus absorbs a neutron and fissions spontaneously, releasing additional neutrons. ...

condenser

Energy; Nuclear energy

A large heat exchanger designed to cool exhaust steam from a turbine below the boiling point so that it can be returned to the heat source as water. In a pressurized-water ...

annual limit on intake (ALI)

Energy; Nuclear energy
