Non-ionizing radiation as possible carcinogen
International Journal of Environmental Health Research, 2020The advent of wireless technologies has revolutionized the way we communicate. The steady upsurge in the use of mobile phone all over the world in the last two decades, while triggered economic growth, has caused substantial damage to the environment, both directly and indirectly.

Proposal for dosimetry of non-ionizing radiation
Lasers in Medical Science, 1989In general “Dose” by itself as an amount of energy is not a relevant parameter for the description of penetration by non-ionizing (laser) radiation. But dosimetry should not only include the measurements of relevant parameters and its relatioships to tissue effects but also include all possibilities of measurements and relationships which help to ...

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: Fact and fiction [PDF]
Technology and Society, 1981 Public 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.

Non-ionizing Electromagnetic Radiation and Environmental Security [PDF]
, 2004 Electromagnetic radiation (ER) is an essential component of the Universe. ER is generated by stars, including Sun, all the time. From these sources, ER with the speed of light, reaches all other objects in the Universe, including Earth. All other objects in the Universe (including Earth) also generate (radiate with the intensity which depends on ...

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.

Metrological aspects of non-ionizing radiation control
Automation and Remote Control, 2011Domestic and foreign regulatory databases regarding the allowable levels of nonionizing radiation are analyzed; as the result, major requirements to measuring devices used in non-ionizing radiation control are formulated. A brief description of P3-31 electromagnetic radiation meter (which satisfies the stated requirements) is provided.

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.

Non-Ionizing Radiation measurements in hospital environments
2015 XVI Workshop on Information Processing and Control (RPIC), 2015As a first step toward the objective of the Technological Development Project called Optimization and Control of Non-Ionizing Radiation (NIR) [1] we measured-for different bands of the radio-electrical spectrum-the various levels of electric field detected at the Corrientes Institute of Cardiology.
