Shield, английский
- Bouclier;écran de protection
- A design carved or chipped out on the slabs of breton tombs. it is a highly version of an antropomorphic figure
- Any barrier to the passage of interference causing electrostatic or electromagnetic fields, formed by a conductive layer surrounding a cable core. it is usually fabricated from a metallic braid, foil or wire serving.
- Sylvania high intelligence electronic defense
- A double rivet with an ornamental head joining both rivets, normally used to attach hinges or other components to a frame.
- A metallic layer that surrounds insulated conductors in a shielded cable; may be the metallic sheath of the cable or a metallic layer inside a nonmetallic sheath; especially effective in providing protection against electrostatic interference.
- Функциональный экран
- Щит; экран; защита || защищать; экранировать
- A conductive enclosure (usually metallic) around one or more signal conductors, used to keep out electrostatic fields that can cause hum, buzz, or other noise.
- A metal frame used to maintain the opening as the tunnel boring progresses. as forward progress is made, the liner is constructed behind the shield, and the shield is jacked or moved forward.
- A layer or mass of material used to reduce the passage of ionizing radiation.

Shield coverage, английский
The amount of cable core surface area which is covered by a shield. it is expressed as a percentage of the cable core's total surface area. it is also called braid coverage when applied to a braided shield.

- A tab within the exchange administration center (eac) that contains anti-virus/anti spam, and data loss protection.
- The process of protecting data from loss or corruption by centrally creating and maintaining replicas and shadow copies of the data. dpm is designed to provide short-term disk-based backup, to support rapid and reliable recovery of data.
- In a specialised sense, used for the rules governing the protection given to a train which stops in an unusual location or becomes derailed, to stop another train hitting it.

Sieverts, английский
The sievert (sv) is the si unit of equivalent dose & effective dose . the equivalent older unit is the rem where 1sv = 100 rem.
Scintillation, английский
- With respect to radiation protection , scintillation is the process where by a material will emit light photons when exposed to ionising radiation . the light photons can be measured with a photo-multiplier tube which will multiply the events to produce a
- This term is used to describe the rapid changes in irradiance levels in a cross section of a laser beam produced by atmospheric turbulence.
- The mirrorlike reflections a diamond’s facets make when it is turned while being exposed to light.
- Scintillation is the intense sparkle that comes from a diamond when it moves. black and white sparkles of scintillation show well in flood lit or office lighting environments where fire can be totally absent. under pin point or spot lights fire also adds to scintillation.
- Emission of light of specific frequencies after the absorption of electromagnetic radiation, such as x-rays or gamma rays.
