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). Non-ionizing radiation is produced by electricity, cell phones, microwaves, WiFi and Bluetooth signals, infrared scanners, and communications devices. 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 • The NIR spectrum is divided into two main regions, … Common names for various energies of EM radiation: Types of EM Radiation. Here we are concerned with only one type of radiation, ionizing radiation, which occurs in two forms - waves or particles. 0000021716 00000 n Source: Data are from World Health Organization, International Agency for Research on Cancer, Ionizing Radiation, Part 1: X- and Gamma (γ)-Radiation, and Neutrons, IARC Monographs, 2000, vol. 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. Non Ionizing Radiation Safety and Chemical Safety - Non Ionizing Radiation Safety and Chemical Safety SK Dua, Ph. 0000028340 00000 n Ionizing radiation can remove electrons from the atoms, i.e. You can change your ad preferences anytime. 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. Instead of producing charged ions when passing through matter, non-ionizing electromagnetic radiation has sufficient energy only for … 0000027098 00000 n 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. 0000024286 00000 n 0000001226 00000 n 0000001757 00000 n H�b```�S� 0000002125 00000 n Microwave Frequencies 4. 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. 3.1 Non-ionizing radiation . Non-ionizing radiation, Part II: Radiofrequency electromagnetic fields / IARC Working Group on the Evaluation of Carcinogenic Risks to Humans (2011: Lyon, France) (IARC monographs on the evaluation of carcinogenic risks to humans ; v. 102) 1. 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. ´�����W�(�f�L�:��8���
