Medical Uses of Electromagnetic Radiation
Electromagnetic radiation or EM radiation is "combination of oscillating electric and magnetic fields perpendicular to each other, moving through space as a wave, effectively transporting energy and momentum" (Electromagnetic pp).
EM radiation is quantized as particles called photons, and the physics of electromagnetic radiation is electrodynamics, a sub-field of electromagnetism (Electromagnetic pp). Generally, EM radiation is classified by wavelength into electrical energy, radio, microwave, infrared, the visible region, ultraviolet, X-rays and gamma rays (Electromagnetic pp).
Radiology is the branch of medicine that specializes in the use of X-rays, gamma rays, radioactive isotopes, and other forms of radiation used in the diagnosis and treatment of disease (Radiology pp). X-ray machines...
The computerized axial tomography, or CAT, scan uses computer technology to focus X-rays on precise sections of the body, while, magnetic resonance imaging, MRI, uses "supercooled" magnets to focus radiation on very small areas of the body, rendering sharp detail (Radiology pp). "Radioactive isotopes are also employed in diagnosis, e.g. iodine-131 is used to confirm cases of suspected thyroid disorder. In radiotherapy, X rays, gamma rays, and other radiation sources are used in the treatment of cancer and related diseases" (Radiology pp).
Vitamin D is produced by the action of ultraviolet radiation on ergosterol, a substance present in the human skin and in some lower organisms, and treatment or…
