What is non-ionising radiation? | ARPANSA
Non-ionising radiation is found at the long wavelength end of the spectrum and may have enough energy to excite molecules and atoms causing then to vibrate faster. This is very obvious in a microwave oven where the radiation causes water molecules to vibrate faster creating heat. Non ionising radiation ranges from extremely low frequency ...
Radiobiological effects and medical applications of non-ionizing radiation
The biological effects of UV radiation depend on the wavelengths involved. The wavelength of the non-ionizing UV spectrum is shorter than that of visible light but longer than an X-ray (100 nm [nm] to 400 nm). It is classified according to intensity: UV-A (315–400 nm), UV-B (280–315 nm) and UV-C (100280 nm) ( Kim et al., 2016 ).
Types of Radiation
Non-ionizing radiation is the term given to radiation that has insufficient energy to cause ionisation. These kinds of radiation contradict ionising radiation like x-rays, gamma rays, and alpha particles, which are on the other end of the spectrum and are unstable and reactive. Non-ionizing radiation can produce heat, which is how food is ...

Infra-red rays are used for the rapid mass ...
3.2.3: Ionizing Radiation and Non-Ionizing Radiation
The greater the likelihood that damage will occur by an interaction is the ionizing power of the radiation. Ionizing radiation could affect either the whole body (somatic damage) and/or eggs and sperm (genetic damage).

The Effects of Ionising and Non-Ionising Electromagnetic Radiation …
In the case of non-ionising radiation, exposure of skin to ultraviolet radiation (UVR), for example, may be beneficial, as a consequence of vitamin D production, or detrimental, due photoageing and/or photocarcinogenesis . UVR is considered non-ionising as it is, in general, not sufficiently energetic to remove electrons from biomolecules.
Non-Ionizing Radiation
Non-ionizing radiation (NIR) permeates the world around us and exists in many forms on the electromagnetic spectrum, from radio waves to near-ultraviolet radiation. Fortunately, in contrast to ionizing radiation, NIR lacks sufficient energy to remove electrons from atoms and molecules and is generally perceived as less harmful.
Ionizing Radiation
Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation. The table below contains estimates of the energies of various kinds of radiation. Radio waves, microwaves, infrared radiation, and visible light are all forms of non-ionizing radiation.
