    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

    en.wikipedia.org/wiki/Radiation_protection

    Radiation exposure can be managed by a combination of these factors: Time: Reducing the time of an exposure reduces the effective dose proportionally. An example of reducing radiation doses by reducing the time of exposures might be improving operator training to reduce the time they take to handle a radioactive source.

    Making a ton of primary aluminum consumes at least 12,500 kW-hr, and most plants consume 14,500 to 15,000 kW-hr per ton of primary aluminum. [18] Secondary production of a given unit of aluminum requires about 10% of the electricity of primary production. The United States mined production of bauxite for primary aluminum production is ...
