Electrons in orbitals with high penetration can shield the nucleus from less penetrating electrons. Because they are closer to the nucleus on average, they repel those farther away and lessen the effe [..]

Protection facility around radioactive sources and nuclear installations to reduce their radiation to the outside according to the requirements. (See 'shield, biological', 'shield, ther [..]

protective material or device.

Any material or obstruction that absorbs radiation and thus tends to protect personnel or materials from the effects of ionizing radiation.

See shield.

Any material or obstruction that absorbs radiation and thus tends to protect personnel or materials from the effects of ionizing radiation.

A protective barrier, usually a dense material, which reduces the passage of radiation from radioactive materials to the surroundings.

Shieldling is a major protection principle for reducing exposure to Ionising Radiation (the two other related principles being Time and Distance ). See Lead for a shielding example.

Any material or obstruction that absorbs radiation and thus tends to protect personnel or materials from the effects of ionizing radiation.

(Animation) (Illustration) the material between a radiation source and a potentially exposed person that reduces exposure.

(n) the act of shielding from harm(n) a shield of lead or concrete intended as a barrier to radiation emitted in nuclear decay(n) shield consisting of an arrangement of metal mesh or plates designed t [..]

Imposing a metallic barrier to reduce the coupling of undesirable signals.

An opaque material that blocks the transmission of light.

In the context of NMR spectroscopy shielding is the effect of the electron shells of the observed and the neighbouring nuclei on the external magnetic field. The external field induces circulations in the electron cloud. The resulting magnetic moment is oriented in the opposite direction to the external field, so that the local field at the central [..]

Also called "Screening"; the ball carrier protects the ball from an opponent by positioning himself between his opponent and the ball.

An opaque material that blocks the transmission of light.

keeping possession and control of the ball by using the body to come between the ball and the opponent

The tactic of a ball carrier putting his body between the ball and the defender.  

The process of applying a conducting barrier between a potentially disturbing noise source and electronic circuitry. Shielding may be accomplished by the use of metal barriers, enclosures, or wrapping [..]

A Common protection method against psychic attack, and being fed upon. Succubus

Blocking an electric or magnetic field with a metallic substance. The incident field induces currents in the metallic substance, and these currents induce a field that opposes the incident field. Shielding reduces radiated electromagnetic waves. Electronic components, wires, lamps, and devices can all be shielded.

a radiation-absorbing material that is used to decrease radiation leakage from nuclear reactors

Also called “Screening”; the ball carrier protects the ball from an opponent by positioning himself between his opponent and the ball.

A metallic covering used to prevent magnetic or electromagnetic fields from affecting an object. Technique designed to minimize internal and external interference. Shielding is required in electrical [..]

The process of shielding pieces of apparatus from the effect of electrostatic fields which are external to the apparatus itself. *shielding protective coating that helps eliminate electromagnetic and radio frequency interference.

The practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials.
