The widespread application of electromagnetic radiation (EMR) in modern medicine requires healthcare professionals and undergraduates to be familiar with its physical and biological properties. The aim of this paper was to review current literature on EMR physical principles. Available literature on EMR ...
电磁波谱(Electromagnetic spectrum) 电磁波谱(Electromagnetic spectrum) What are visible light, infrared ray, ultraviolet ray, X ray and gamma ray? Analysis: in the electromagnetic radiation of solar radiation, the electromagnetic wave that can cause the human eye vision is 0.76 ~ 0.4 microns (7600...
which the eyes cannot see but whose effect is felt as pain fromsunburn. Ultraviolet light represents a kind of electromagnetic radiation that can be harmful tolife. Such is also true ofX-rays, which are important inmedicineas they allow physicians to observe the inner parts of the body but ...

X-rays are commonly used for imaging in medicine and security. X-rays are very penetrating, which means they are difficult to stop; this allows them to be used for creating images of bones. They are only absorbed by dense material like bone and metal and can easily travel through soft tis...
The millimeter waves (MMW) region of the electromagnetic spectrum, extending from 30 to 300 GHz in terms of frequency (corresponding to wavelengths from 10 mm to 1 mm), is officially used in non-invasive complementary medicine in many Eastern European countries against a variety of diseases such...
X rays: A very useful type of high-energy wave widely used in medicine and security. Find out more in our main article on X rays. Typical size: 0.1 nanometers (the width of an atom). Gamma rays: These are the most energetic and dangerous form of electromagnetic waves. Gamma rays are...
Electromagnetic radiation with very short wavelengths and high frequencies fall into the cosmic ray/gamma ray/ultraviolet radiation region. At the other end of the spectrum are the long wavelength, low frequency forms of radiation: radio, radar, and microwaves. In the middle of the range is ...

Muhammad Iqbal, in An Introduction to Solar Radiation, 1983 Publisher Summary Matter can emit electromagnetic radiation by molecular and atomic agitation. The spectrum of electromagnetic radiation encompasses γ rays, X rays, ultraviolet radiation, light, heat, radio waves, and radar waves. This chapte...
