ABSTRACT
This chapter reviews the safety standard for electromagnetic radiation with some focus placed on the near-field aspects as well as the set standards for handheld devices. The general public is very much aware that people cook food and heat meat in microwave ovens and having handheld devices near the human head is certainly discomforting and a cause of serious concern. From the antenna engineering point of view, this area of human body interactions with antennas is intriguing and represents divergence from standard procedures for designing antennas for wireless communications. Determination of exposure standards and safety levels of radio frequency radiation has been a research area of significant interest for over three decades and, in particular, since 1966 with the publication of a safety standard by the United States of America Standards Association, currently known as the American National Standards Institute.
