Ultraviolet rays are germicidal in nature and destroy bacteria, viruses and moulds from various surfaces, air or water. In comparison with both mechanics and optics, however, the science of electricity was slow to develop. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. The waves that are used in this way are radio waves, microwaves, infrared radiation and light. 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). The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.. As EM energy travels through the space, it behaves either longitudinal or transverse waves and it contains both components of electric and magnetic fields. This chapter contains new simulation results concerning the physical foundations of how microwave tubes operate based on Cherenkov’s mechanism of radiation (interaction with slow electromagnetic wave) and some experimental results connected with improving the output characteristics of the magnetrons (a mm band surface wave magnetron and a magnetron with two RF … Fortunately, a few simple lifestyle adjustments can reduce the health risks. Electromagnetic radiation is used for communications and transmission of information. A discussion of the various methods used to detect electromagnetic energy is beyond the scope of this TRAMAN. Electromagnetic waves are free to radiate without the help of moving charges that produce them as they have enough distance. Solar electromagnetic radiation is generated by the extremely hot plasma of the Sun, and this thermal radiation heats the Earth by the reverse process of absorption, generating kinetic, thermal energy in electrons and atomic nuclei. 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. However, we must emphasize the importance of remaining alert to the danger of overexposure to electromagnetic radiation. The electromagnetic rays and radiations emitted by these elements is also of immense importance both medically and industrially. Examples of non-ionizing radiations are: • Static electromagnetic fields from direct current (0 Hz) • Low-frequency waves from electric power (50-60 Hz) • Extremely Low Frequency (ELF) All electromagnetic waves move at the speed of light, including light itself. Unfortunately, all of today’s technology emits Electromagnetic Radiation, or Electromagnetic Field (EMF) radiation, which can cause health problems over time which include fertility issues, DNA damage, electromagnetic hypersensitivity, and many other health concerns. 7 Regions of the Electromagnetic Spectrum 769 Words | 4 Pages. Electromagnetic radiation - Electromagnetic radiation - Relation between electricity and magnetism: As early as 1760 the Swiss-born mathematician Leonhard Euler suggested that the same ether that propagates light is responsible for electrical phenomena. 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 radiation having many hazardous effects on human beings and other living forms has the other side of having disease curing effect. 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. The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. Electromagnetic radiation: The Electromagnetic radiation are considered as a waves of the energy. The idea of using a signal lamp to communicate was used in the 19th century. For GCSE physics revision. EMR Impairments To Immune System – The immune system is impaired in the presence of Electromagnetic radiation is a form of energy that is emitted and absorbed by charged particles known as electrons. Electromagnetic radiation above 2500 × 10 6 MHz is mostly referred to as ionizing radiation. 10 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. (There are 1 million micrometers in one meter.) Radiation is energy in the form of waves or particles that comes from a source and travels through space or through a medium. Electromagnetic waves are produced by the motion of electrically charged particles. Infrared radiation is very close to optical light, and therefore very similar techniques are … in various activities within the electromagnetic environment. 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. Some traditional applications that use electromagnetic radiation include the entire family of therapies known as electrophysical agents. Since thermal radiation is electromagnetic radiation, the properties of the propagation of electromagnetic waves can be applied. These waves are also called electromagnetic radiation because they radiate from the electrically charged particles. 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 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. Electromagnetic (EM) radiation occurs both naturally (e.g., sunlight) and from man-made sources (e.g., wireless devices). Electromagnetic field produce electromagnetic radiation also referred to as EM radiation. 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. In this piece of article, we will discuss electromagnetic radiation and its properties. The Earth also emits thermal radiation, but at a much lower intensity because it is cooler. The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. 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. Sources: Dr. Neal Cherry (2000), Burch et al. Researchers Create an Electromagnetic "Black Hole" the Size of a Salad Plate. 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. Uranium is a very radioactive element that occurs in several parts of the globe and can be used in the production of nuclear weapons whose destructive effects is … This method of long distance communication … HEAT Solar electromagnetic radiation is generated by the extremely hot plasma of the Sun, and this thermal radiation heats the Earth by the reverse process of absorption, generating kinetic, thermal energy in electrons and atomic nuclei. They travel through empty space as well as through air and other substances. 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. The Earth also emits thermal radiation, but at a much lower intensity because it is cooler. 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. OR.
