Abstract

EMF (Electromagnetic Field) is a valuable resource for living in a knowledge-based information society. The EMF is used in home appliances that make our lives easy and convenient, and in telecommunication devices such as mobile phones, personal computers, medical devices and broadcasting towers. However, the biological hazards associated with EMF exposure are also increasing in signal from telecommunication devices. Studies of the effects of EMF exposure on humans have been conducted for a long time, but it has not yet been demonstrated whether the EMF effect is harmful. In this paper, we examine the electromagnetic field emitted from various electronic devices around living and its effect.

EMF (전자기장)는 지식 기반 정보 사회에서 살기위한 귀중한 자원 중 하나다. EMF는 우리의 삶을 쉽고 편리하게 만들어주는 가전제품과 휴대 전화, 개인용 컴퓨터, 의료 기기 및 방송 타워 등의 정보 통신 기기에 사용된다. 그러나 EMF 노출과 관련된 생물학적 유해성은 전기 통신 장치로부터의 신호도 증가하고 있다. 인체에 대한 EMF 노출의 영향에 대한 연구가 오랫동안 수행되었지만 EMF 효과가 유해한 지 여부는 아직 증명되지 않았다. 본 논문에서는 생활주변의 각종 전자기기로부터 방출 되는 전자장과 그 영향에 대해서 고찰한다.
