||The Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) has updated the previous opinion on ”Possible effects of Electromagnetic Fields (EMF), Radio Frequency Fields (RF) and Microwave Radiation on human health” by the Scientific Committee on Toxicity, Ecotoxicity and the Environment (CSTEE) from 2001, with respect to whether or not exposure to electromagnetic fields (EMF) is a cause of disease or other health effects. The opinion is primarily based on scientific articles, published in English language peer-reviewed scientific journals. Only studies that are considered relevant for the task are cited and commented upon in the opinion. The opinion is divided into frequency (f) bands, namely: radio frequency (RF) (100 kHz < f ≤ 300 GHz),intermediate frequency (IF) (300 Hz < f ≤ 100 kHz), extremely low frequency (ELF)(0< f ≤ 300 Hz), and static (0 Hz) (only static magnetic fields are considered in this opinion). There is a separate section for environmental effects.
