Radiation Studies - CDC: Non-Ionizing Radiation
www.cdc.gov › nceh › radiationDec 07, 2015 · Put simply, non-ionizing radiation differs from ionizing radiation in the way it acts on materials like air, water, and living tissue. Unlike x-rays and other forms of ionizing radiation, non-ionizing radiation does not have enough energy to remove electrons from atoms and molecules. Non-ionizing radiation can heat substances.
Non-Ionizing Radiation - National Institutes of Health
ors.od.nih.gov › sr › dohsNon-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.
