The Earth also emits thermal radiation, but at a much lower intensity because it is cooler. Indeed, studies have linked low-level electromagnetic radiation (EMR) exposure from cellphones to an 8 percent reduction in sperm motility and a 9 percent reduction in sperm viability. The electromagnetic rays and radiations emitted by these elements is also of immense importance both medically and industrially. The uses of electromagnetic waves, this section describes some of the qualities and uses of different waves on the electromagnetic spectrum. Electromagnetic waves are produced by the motion of electrically charged particles. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an … Electromagnetic waves are free to radiate without the help of moving charges that produce them as they have enough distance. Electromagnetic Radiation and Life: Bioelementological Point of View 195 influence of millimeter wave radiation there is observed increased accumulation of a number of trace elements from the environmen t: selenium, chromium, zinc, copper, lithium, etc., with dramatic change in elemental composition of the algal cells (Tambiev et al., 2000-2011). It was known from Maxwell’s equations that this radiation traveled at the speed of light and from this it was realized that light itself, and the closely related infrared heat radiation, were actually electromagnetic waves. For this purpose, some measurements were carried out with Narda EMR-300 radiation meter which has a capability of measuring total electromagnetic radiation level from 100 kHz to 3 GHz frequency. The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. The ionizing radiation source could be an electron beam, x-rays (machine generated), or gamma rays (from Cobalt-60 or Cesium-137), and the energy of a gamma ray is above 2 × 10 −14 J. The waves that are used in this way are radio waves, microwaves, infrared radiation and light. These are discussed in more detail later in this section but generally are used with the purpose of reducing pain, muscle spasms, inflammation, and/or improving superficial/deep circulation status and subsequent healing potential. 8, 9 Wi-Fi equipped laptop computers have also been linked to decreased sperm motility and an increase in sperm DNA fragmentation after just four hours of use. These equations state that electromagnetic radiation consists of quantized, traveling fluctuations in the electromagnetic field. Electromagnetic Radiation (EMR) • is radiated by atomic particles at the source (the Sun), • propagates through the vacuum of space at the speed of light, • interacts with the Earth's atmosphere, • interacts with the Earth's surface, • interacts with the Earth's atmosphere once again, and In comparison with both mechanics and optics, however, the science of electricity was slow to develop. Electromagnetic Radiation (EMR), with energy levels below that required for effects at the atomic level. Radiation: Here, Radiation is defined broadly to include charged particles such as alpha α and beta β radiation. Infrared radiation is very close to optical light, and therefore very similar techniques are … Fortunately, a few simple lifestyle adjustments can reduce the health risks. However, we must emphasize the importance of remaining alert to the danger of overexposure to electromagnetic radiation. in various activities within the electromagnetic environment. The most relevant ones are the frequency v and the wavelength λ, which are related through λ = c/v, where c is the speed of light in the medium. They travel through empty space as well as through air and other substances. Sources: Dr. Neal Cherry (2000), Burch et al. Ultraviolet rays are germicidal in nature and destroy bacteria, viruses and moulds from various surfaces, air or water. The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. Many people think that electromagnetic radiation is not dangerous, while there are others in the scientific community who are still doing studies on this subject. Electromagnetic radiation exists across a wide range of frequencies and can be organized on a frequency spectrum as follows: radio waves, infrared waves, visible light, ultraviolet rays, x-rays, and gamma rays. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. OR. Radiation is energy in the form of waves or particles that comes from a source and travels through space or through a medium. For this reason, experts refer to electromagnetic radiation as the ‘far-field.’ 4. All EM waves are made up of photons that travel through space until they interact with matter; some waves are absorbed and others are reflected. Electromagnetic Radiation in Quantum Mechanics In this piece of article, we will discuss electromagnetic radiation and its properties. The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi. Electromagnetic radiation is a form of energy that is emitted and absorbed by charged particles known as electrons. Melatonin Reduction – Electromagnetic Radiation reduce the levels of melatonin in the human body. All electromagnetic waves move at the speed of light, including light itself. EMR Impairments To Immune System – The immune system is impaired in the presence of (There are 1 million micrometers in one meter.) Electromagnetic radiation is the foundation for working of radar which in turn is used for guiding and remote sensing the study of our planet Earth. Electromagnetic radiation consists of waves of electric and magnetic energy moving together (i.e., radiating) through space at the speed of light. Electromagnetic radiation, the larger family of wave-like phenomena to which visible light belongs (also known as radiant energy), is the primary vehicle transporting energy through the vast reaches of the universe. The electromagnetic spectrum includes radio and TV waves, microwaves, infrared, visible light, ultraviolet, x-rays, g-rays, and cosmic rays, as shown in the figure above. This method of long distance communication … The Earth also emits thermal radiation, but at a much lower intensity because it is cooler. For GCSE physics revision.
