nonionizing radiation

[-ī′ənī′zing]
Etymology: L, non + Gk, ion, going, izein, to cause
radiation for which the mechanism of action in tissue does not directly ionize atomic or molecular systems through a single interaction.

nonionizing radiation

Abbreviation: NIR
Electromagnetic radiation that does not readily ionize atoms such as that in visible light, ultraviolet light, infrared light, microwaves, ultrasound, and radiofrequency emissions.

Interestingly, the inert properties of asbestos, mentioned earlier, may compound the effects of nonionizing radiation, since both interfere with cell signaling by different mechanisms.
Nonionizing radiation exposure can be measured and usually minimized, which is prudent, given the suggestive results of ongoing research and how much we don't yet know.
The environmental risk factors we discuss in this article include some of the more researched and controversial topics including ionizing and nonionizing radiation, chemicals such as hydrocarbons and pesticides, alcohol, tobacco use, and illicit drug use.

The overarching clinical message is that nonionizing radiation can encroach on health in often subtle ways.
nonionizing radiation exposures: homes, schools, and workplaces
Public concerns about the potential health effects of exposure to RF nonionizing radiation stem partly from the pervasiveness of these exposures.
Several publicly accessible areas closest to these towers have exceeded the general public nonionizing radiation standard (200 [micro]W/[cm.
As the debate regarding the health implications of exposure to nonionizing radiation continues, an increased effort must be made to evaluate factors that predict exposure to RF fields.
We should work for more research to determine risk factors and cause, better tools and tests to assess risk, research on more accurate and nonionizing radiation imaging techniques for screening, laboratory testing for markers of breast cancer, and more aggressive risk-reduction strategies.
Conversely, UV and visible light that do not cause ionization are called nonionizing radiations.
