Non-ionizing radiation (NIR) refers to electromagnetic radiation that does not have sufficient energy to ionize (remove electrons from) atoms or molecules. <<2B0870A0C083E84E8D63B295012E9470>]>> Ionizing radiation is a form of energy that acts by removing electrons from atoms and molecules of materials that include air, water, and living tissue. NOTE: This procedure does not cover non-ionizing radiation generated during welding, cutting, or burning activities. 1. ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. UV radiation is generally classified as non-ionizing radiation; however, in Figure 9.5, it appears to be on the cusp of non-ionizing and ionizing radiation. Instead of producing charged ions when passing through matter, non-ionizing electromagnetic radiation has sufficient energy only for … Ionizing radiation can travel unseen and pass through these materials.

Ionizing radiation … Ionizing radiation directly damages the covalent bonds of your DNA, while non-ionizing radiations create hydroxyl free radicals (OH-), causing indirect damage. Gamma rays, x-rays, photons) travel through a medium or space.Radioactivity is the spontaneous nuclear transformation that results in the formation of new elements. Ionizing radiation contains enough energy to remove an electron (ionize) from an atom or molecule and to damage DNA in cells. xref International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1. +��`�gi�u����� � e�%D+�0X��S�u� v\l����C� 0000001990 00000 n Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF). The key difference between ionising and non ionising radiation is that Ionizing radiation has high energy than the non-ionizing radiation.. 0000025743 00000 n Radiation is classified as being either non-ionizing or ionizing. While most UV radiation is non-ionizing, radiation of higher frequency and higher energy is more powerful, and thus can be considered ionizing.

The use of the term non-ionizing radiation in this document is defined as meaning non-ionizing radiation produced as a result of normal equipment use and which is at such a level that is recognized as harmful to humans. 0000004037 00000 n 0000017033 00000 n <> It is the policy of the University of California at Berkeley to provide a workplace safe from the known hazards of NIR by assuring compliance with federal and state safety regulations. Abstract—Radiofrequency electromagnetic fields (EMFs) are used to enable a number of modern devices, including mobile telecom-munications infrastructure and phones, Wi-Fi, and Bluetooth. Non-ionizing radiation includes the photons with energies at, or below, the middle ultraviolet part of the electromagnetic spectrum, including visible light, infrared, microwaves, and radio waves. Unlike ionizing radiation, non-ionizing radiation does not remove electrons from atoms or molecules of materials that include air, water, and living tissue. 0000003794 00000 n X-rays are used in diagnostic imaging and in therapeutics.
