Non-Ionizing radiation • Non-Ionizing radiation (NIR) refers to radiative energy that, instead of producing charged ions when passing through matter, has sufficient energy only for excitation. Nevertheless it is known to cause biological effects. 0000024286 00000 n
Examples of this kind of radiation are radio waves, visible light and microwaves.Ionizing radiation has so much energy it can knock electrons out of atoms, a process known as ionization. D., CHP, CLSO Bill Youngblut, MS, CIH, CSP Environmental Health & Safety Florida International University | PowerPoint PPT presentation | free to view While most UV radiation is non-ionizing, radiation of higher frequency and higher energy is more powerful, and thus can be considered ionizing. As radiofrequency EMFs at sufficiently high power levels can ad- Types of Non-Ionizing Radiation and Their Clinical Effects - Referring again to the chart above we can see that Non-Ionizing radiation comes in the forms of: 1. Non-ionising radiation is grouped into the region of the electromagnetic spectrum that has a wavelength greater than 100nm or frequencies less than 3x1015Hz (See Figure 1). Microwave ovens use microwaves to heat food, toasters use infrared waves to heat and sometimes burn our toast, and we watch television, talk on cell phones, and listen to the radio through the use of radio waves. 1.

It is termed ‗non-ionising‘ as the photon energy is insufficient to ionise (change atomic structure) of matter. �����$&��0��g�Xk`fB�䀧P&v����,�gb���=1��醕��(���L_Gɭ s�3�r��4ݽaq�R2$�o�"�R�bXs�y���P�a{�r�����

ABSTRACT Non-Ionizing radiation (NIR) refers to radiative energy that, instead of producing charged ions when passing through matter, has sufficient energy only for excitation. Ionizing Radiation Ionizing radiation is radiation with enough energy so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized.

Common names for various energies of EM radiation: Types of EM Radiation. Non-ionizing radiation has less energy than ionizing radiation; it does not possess enough energy to . ) Non-ionizing radiation is a category of radiation that does not have enough energy to ionize molecules or atoms.This inability is due to the low frequency and high wavelength of radiation waves. � �

Non-Ionizing Radiation Safety Policy 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. Ionising radiation is discussed separately.1 Within various references such as ICNIRP (2002) and SA/SNZ (2005), non-ionising radiations include electromagnetic radiations, sound and ultrasound. Non-ionizing radiation (NIR) is a generic term used to describe electromagnetic radiation that does not carry enough photon energy to ionize atoms or molecules and, as per its definition, also includes mechanical waves (infra- and ultrasound).

Non-ionizing (or non-ionising) radiation refers to any type of electromagnetic radiation that does not carry enough energy per quantum (photon energy) to ionize atoms or molecules—that is, to completely remove an electron from an atom or molecule. 12IH401, MIHS Visible Spectrum 7. 0000019569 00000 n
Non-ionizing Radiation, Types, Source, Effects. 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.
