  2. Lead shielding - Wikipedia

    en.wikipedia.org/wiki/Lead_shielding

    Lead shielding refers to the use of lead as a form of radiation protection to shield people or objects from radiation so as to reduce the effective dose. Lead can effectively attenuate certain kinds of radiation because of its high density and high atomic number; principally, it is effective at stopping gamma rays and x-rays.

  3. Radiation protection - Wikipedia

    en.wikipedia.org/wiki/Radiation_protection

    Personal shielding against more energetic radiation such as gamma radiation is very difficult to achieve as the large mass of shielding material required to properly protect the entire body would make functional movement nearly impossible. For this, partial body shielding of radio-sensitive internal organs is the most viable protection strategy.

  4. Lead castle - Wikipedia

    en.wikipedia.org/wiki/Lead_castle

    A lead castle built to shield a radioactive sample in a lab. The bricks are flat-sided Example of chevron lead bricks used to prevent shine paths. A lead castle, also called a lead cave or a lead housing, is a structure composed of lead to provide shielding against gamma radiation in a variety of applications in the nuclear industry and other activities which use ionizing radiation.

  5. Gamma ray - Wikipedia

    en.wikipedia.org/wiki/Gamma_ray

    In astrophysics, gamma rays are conventionally defined as having photon energies above 100 keV and are the subject of gamma-ray astronomy, while radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy. Gamma rays are ionizing radiation and are thus hazardous to life.

  6. Radiation hardening - Wikipedia

    en.wikipedia.org/wiki/Radiation_hardening

    Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), [1] especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear ...

  7. Ionizing radiation - Wikipedia

    en.wikipedia.org/wiki/Ionizing_radiation

    Barriers of lead, concrete, or water are often used to give effective protection from more penetrating forms of ionizing radiation such as gamma rays and neutrons. Some radioactive materials are stored or handled underwater or by remote control in rooms constructed of thick concrete or lined with lead.

  8. Beta particle - Wikipedia

    en.wikipedia.org/wiki/Beta_particle

    Beta radiation, consisting of electrons or positrons, is stopped by a thin aluminum plate, but gamma radiation requires shielding by dense material such as lead or concrete. [ 1 ] A beta particle , also called beta ray or beta radiation (symbol β ), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic ...

  9. Faraday cage - Wikipedia

    en.wikipedia.org/wiki/Faraday_cage

    Faraday cages cannot block stable or slowly varying magnetic fields, such as the Earth's magnetic field (a compass will still work inside one). To a large degree, however, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the
