Web16 sep. 1987 · The electromagnetic spectrum (EMS) includes wavelengths of EM radiation ranging from short-wavelength (high-frequency) gamma rays to long-wavelength (low-frequency) radio waves. We focus on the region of the spectrum starting in the ultraviolet and continuing through the microwave wavelengths. Optical sensors are used … WebParts of the electromagnetic spectrum of thermal radiation may be ionizing, if the object emitting the radiation is hot enough (has a high enough temperature). A common example of such radiation is sunlight, which is thermal radiation from the Sun's photosphere and which contains enough ultraviolet light to cause ionization in many molecules and atoms.
Ionizing radiation - Wikipedia
Web3 mrt. 2024 · There are four basic types of ionizing radiation--alpha, beta, gamma, and neutron--and each has unique properties. Alpha radiation happens when the unstable atom emits two protons and two neutrons—basically a helium nucleus. The original atom, with fewer protons and neutrons, becomes a different element. WebSome representative diagnostic procedures are endoscopy (based on conventional light illumination of internal organs and tissues via physical body cavities), spectroscopy (based on non-ionizing electromagnetic waves), ultrasound imaging (based on high-frequency sound waves) and magnetic resonance imaging (based on strong magnetic fields, … how to send photo to email address
