电磁辐射,是以电磁波的形式并以光速在空中(或其他介质中)传播能量的物理现象。在我国的中学物理教科书以及相关的教学参考资料中,几十年来一直都在介绍电磁辐射的产生、传播、发射、接收以及如何应用电磁辐射造福人类的美好前景。一般并未提及电磁辐射的危害问题。然而,近年来国内外媒体对电磁辐射有害却屡有报道。与此同时,高强度电磁辐射所造成的健康方面的负面影响日益被医学界所重视。本文就电磁辐射的危害及
Electromagnetic radiation is a physical phenomenon that propagates energy in the air (or other medium) in the form of electromagnetic waves and at the speed of light. In China’s secondary school physics textbooks and related teaching reference materials, the good prospect of generating, transmitting, transmitting, receiving and using electromagnetic radiation for the benefit of mankind has been introduced for decades. There is generally no mention of the dangers of electromagnetic radiation. However, in recent years, domestic and foreign media have been reported to be harmful to electromagnetic radiation. In the meantime, the negative health effects caused by high-intensity electromagnetic radiation are increasingly valued by the medical community. This article on the dangers of electromagnetic radiation and
