    en.wikipedia.org/wiki/Electromagnetic_shielding

    RF shielding is also used to protect medical and laboratory equipment to provide protection against interfering signals, including AM, FM, TV, emergency services, dispatch, pagers, ESMR, cellular, and PCS. It can also be used to protect the equipment at the AM, FM or TV broadcast facilities.

    en.wikipedia.org/wiki/Faraday_cage

    Faraday cages are also used to protect people and equipment against electric currents such as lightning strikes and electrostatic discharges, because the cage conducts electrical current around the outside of the enclosed space and none passes through the interior.

    EMF stands for electric and magnetic fields, which, according to the National Institute of Environmental Health and Sciences, are invisible areas of energy often referred to as radiation.

  6. 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.

  7. 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.
