Posted September 16, 2013 ACGIH® Presents Non-Ionizing Radiation and Fields 3 kHz–300 GHz Webinar — November 20, 2013      Electromagnetic radiation (EMR) is a physical agent, but is not homogeneous. The physics, health effects and assessment methods differ over different regions of the EMR spectrum in the occupational environment. It's up to occupational health professionals to determine how to control exposure in the day-to-day setting. This webinar will provide the attendee with a practical understanding of non-ionizing radiation, health effects, current guidelines for exposure, and ways to control and/or prevent exposure in the occupational setting with emphasis on the sub-radiofrequency, radiofrequency and microwave regions of the electromagnetic spectrum. It will also provide basic information to assist in the development of workplace prevention programs. For more information and to register for this exciting event, click here.
