This article addresses health issues related to the electric and magnetic fields of VDTs. It was developed by the Committee on Man and Radiation (COMAR) of the Institute of Electrical and Electronics Engineers, Inc. (IEEE), and represents the considered judgment of an international group with expertise in the subject area. It updates an earlier statement on this topic that was issued in August 1990. The topics discussed include: characteristics and typical strengths of VDT electric and magnetic fields; comparisons with occupational and public exposure guidelines; biophysical factors of static, ELF and VLF fields; health studies in human populations; VDTs and pregnancy; VDTs and electrosensitivity; information from biological experimentation; other reviews of VDT effects; and recommendations for users of CRT-based devices.
