non-ionizing radiation

Electromagnetic radiation, the photons of which lack the energy required to ionize atoms or induce ion formation; NIR includes sound, ultraviolet, visible, and infrared light, microwaves, and radiowaves. Cf Ionizing radiation.

Non-ionizing radiation

Rays of energy that move in long, slow wave patterns and do not penetrate cells.t

Millimeter wave technology (i.e., terahertz nonionizing submillimeter microwave radiation) can see through clothing and provides a fuzzy image of a fully exposed body, enabling a correctional professional to detect potentially dangerous items without touching the inmate.
They benefit from two advantages: firstly, some high frequency electromagnetic waves, such as millimeter waves (MMW) and terahertz waves (THz) can penetrate clothing or packages; secondly, microwaves are nonionizing and, therefore, microwave imaging systems are easily accepted by the public.
Radiologists can advise on the risks and benefits of CT scans, as well as the use of nonionizing imaging methods.
(42,43) Patients can be informed that according to the Safety Committee of the Society for Magnetic Resonance Imaging, MRI is reasonable when other nonionizing forms of radiation are inadequate, or when the study would provide information that would otherwise require exposure to ionizing radiation.
* identifying and removing both ionizing and nonionizing radiation exposure where feasible.
No less than the World Health Organization (WHO) has clarified that radio signals emitted for cell phone services are classified nonionizing radiation, which is relatively harmless like those coming from AM-FM radios or baby monitors, compared to ionizing radiation from x-ray machines, which are deemed to carry higher health risks.
Interaction of incoming particles with matter results in two major effects: ionization energy loss and nonionizing energy loss (NIEL).
This is mainly due to two factors: firstly, the radiation in the MMW band (30-300 GHz) is nonionizing and safe to use and secondly it is able to penetrate through most dielectric materials as well as poor weather conditions such as smoke and fog [1].
Nonionizing radiation--lower-energy radiofrequency waves such as those emitted by microwave ovens and cell phones--doesn't break chemical bonds.
(2) Aside from FAST's advantages of speed, ease of use, portability, noninvasive and nonionizing nature, ultrasound is excellent at detecting intra-abdominal fluid.
These plots show the distributions of ionizing events (commensurate to the Cooper-pair dissociations) and nonionizing events (phononic excitations and atomic displacements) within In[O.sub.x] films.
Independent researchers have documented harmful biological effects of this nonionizing radiation; but returning to a less technological, less connected world isn't plausible.
