Non-ionising radiation (NIR) is the term used to describe the part of the electromagnetic spectrum covering two main regions. Firstly, optical radiation (ultraviolet (UV), visible and infrared) and ...

Non-Ionizing radiation is a radiation on the electromagnetic spectrum with the inability to remove an electron from an atom (Ionize). The University of Massachusetts Lowell has a non-ionizing ...

In contrast, non-ionizing radiation does not have enough energy to alter the electron structure; however, it may be harmful depending on the amount of exposure. See ion and electromagnetic ...

UV radiation is invisible to the eye and it is non-ionizing form of radiation in the 100 nm to 400 nm wavelength region of the electromagnetic spectrum. UV radiation is arbitrarily divided into UV-A ...

Terahertz waves, known as non-ionizing radiation ... Lying between the microwave and infrared regions of the electromagnetic spectrum, the terahertz (1 THz = 10¹² Hz) gap is being rapidly ...

with a particular bias towards ionising and non-ionising electromagnetic radiation and its diagnostic role in medicine. The module begins with the generation and behaviour of electromagnetic waves and ...
