Countering the constant bombardment of radiation ever present in the 21st century. Although people can try to block electromagnetic radiation, that is almost impossible unless they live in a Faraday cage. However, there are various devices that mimic natural radiation to counter the effects of manmade radiation. See
electromagnetic hypersensitivity and
Faraday cage.
Blushield EMF Protection
Devices such as this stationary unit from Blushield Global emit natural radiation that overpowers manmade radiation. Portable units are also available. According to the website, the devices emit waveforms that never stimulate the body twice with the same combination of frequencies at the same amplitude. (Image courtesy of Blushield Global USA.)
