Radiation-protection regulations concern ionizing radiation like α, β, γ radiation and neutrons. Separate regulations concern the handling of X rays and X-ray-generating devices. γ radiation and X rays are electromagnetic waves: they differ from visible light or microwave radiation only by their energy or, equivalently, by their frequency or wavelength.

Photonic and non-ionizing cosmic radiation
Physica, 1946Summary We extended our investigations concerning the amount of photons and particles in cosmic radiation, to the region of energies higher than 10 7 evolts. For this purpose we recorded simultaneously the ionizing particles and the non-ionizing ones which produced in a layer of lead at least one or two electrons (principle of anticoincidences).

Non-ionizing radiation safety: radiofrequency radiation, electric and magnetic fields
Physics in Medicine and Biology, 1992The static, low-frequency and radiofrequency parts of the electromagnetic spectrum are used in various areas of human activity. Equipment utilizing this energy today is to be found in industry, medicine, commerce and private homes. The author provides a short survey of the biological effects and concentrates on the principal experimental and ...

Effects of Non-Ionizing Radiations on Viruses
1957Publisher Summary This chapter discusses the effects of nonionizing radiations on specific biological activities of viruses. Both (ionizing and nonionizing) kinds of radiations are electromagnetic waves emitted in quanta and they differ from one another only in the ranges of their wavelengths.

РАДИАЦИОННАТА БЕЗОПАСНОСТ В СЪВРЕМЕННИЯ СВЯТ
The Earth's permanent magnetic field operates everywhere on the Earth's surface. It varies depending on geographical coordinates, as well as due to anomalies associated with the presence of iron ore deposits in certain geographical areas, but in the sense cited, it is a universal factor of the environment. The same applies to the electrostatic field,

Non-ionizing radiation: Fact and fiction
Technology and Society, 1981Public awareness of the “potential health hazards” of RF and microwave radiation dates from the disclosure, in 1972, of Russian irradiation of the U.S. Embassy in Moscow. Previously, so-called “death rays” had been relegated to the pages of science fiction.
