Material with shielding properties, such as concrete or steel, used to reduce the intensity of ionizing radiation.
protection from gamma rays and Xrays by use of dense materials such as metal, concrete, or certain soils. SIGSEC-- signal security SITREP-- situation report SOP-- standing operating procedures
Material used in a radiation shield. A synonym for shield. Related to radiation shielding.
a shield of lead or concrete intended as a barrier to radiation emitted in nuclear decay
the material between a radiation source and a potentially exposed person that reduces exposure.
A protective barrier, usually a dense material, which reduces the passage of radiation from radioactive materials to the surroundings.
Barrier of attenuating material used to reduce radiation exposure.
The use of absorbing material between a source of radiation and the detector or recipient. Shielding absorbs radiation and reduces the intensity of the incident radiation. It does not change the energy of the incident radiation. Shielding is chosen on the basis of its effectiveness for a given type of radiation, its cost and other physical attributes.
Reduction of radiation by interposing a shield of absorbing material between any radioactive source and a work area or radiation-sensitive device.
Material placed between the source of radioactive material and the body to reduce external exposure.
lead or tungsten foils which minimise the radiation crosstalk from exterior
Comprises the various materials within a nuclear power plant preventing radiation from escaping into the environment. Shielding can be steel, lead, concrete or water.
an electrostatic field radiates in the area surrounding most charged objects. This field can produce an ESD event or inductively charge other objects nearby and produce undesirable results. A conductive, grounded enclosure, such as a Faraday cage, that completely surrounds an object will shield the contents within from the effects of an external electrostatic field. A metallized bag or a conductive tote box are examples of shielding.
Material used to block or absorb radiation. Often placed between sources of radiation and people or the environment.
material, such as lead or concrete, used around a nuclear reactor to prevent the escape of radiation and to protect workers and equipment.
a barrier which is placed around radioactive substances which stops the radiation from passing through it.
The act or process of protecting or supplying with a protective device or screen. An example is a screen that protects against radiation.
