nuclear gauge
1gauge particle — gauge particle, Nuclear Physics. any of a group of elementary particles whose function is to transmit forces between other particles: »When the Sun lights the earth, the energy is transmitted…by photons, the gauge particles of electromagnetism.… …
2Nuclear densometer — A nuclear densometer is a field instrument used in geotechnical engineering to determine the density of a compacted material. Also known as a soil density gauge, the device uses the interaction of gamma radiation with matter to measure density,… …
3Nuclear meltdown — Three of the reactors at Fukushima I overheated, causing core meltdowns. This was compounded by hydrogen gas explosions and the venting of contaminated steam which released large amounts of radioactive material into the air.[1] …
4Nuclear density gauge — A nuclear density gauge is a tool used in civil construction and the petroleum industry, as well as for mining and archaeology purposes. It consists of a radiation source that emits a directed beam of particles and a sensor that counts the… …
5Gauge theory — For a generally accessible and less technical introduction to the topic, see Introduction to gauge theory. In physics, a gauge theory is a type of field theory in which the Lagrangian is invariant under a continuous group of local transformations …
6Nuclear Densometer Test — A Nuclear Densometer Test is a field test used in geotechnical engineering. The test is performed on a compacted base to establish its percentage of compaction. Before field tests are performed, the technician performs a calibration on the gauge… …
7nuclear hydrogen detection meter — noun A device that contains a radioactive source to emit high velocity neutrons into a roof system. Reflecting neutrons are measured by a gauge that is used to detect hydrogen; the quantity of hydrogen detected may be linked to the pressure of… …
8Introduction to gauge theory — This article is an accessible, non technical introduction to the subject. For the main encyclopedia article, see Gauge theory. Quantum field theory …
9Simetría de gauge — En la expresión simetría de gauge, la palabra gauge significa medida , y simetría significa que algo se mantiene igual al cambiar alguna condición externa. La simetría de gauge es un principio de simetría que subyace a descripción mecánico… …
10Interacción nuclear fuerte — Cuadro explicativo de las 4 fuerzas fundamentales. La interacción nuclear fuerte es una de las cuatro interacciones fundamentales que el modelo estándar de la física de partículas establece para explicar las fuerzas entre las partículas conocidas …
