电磁辐射危害人体的机理主要是热效应、非热效应和累积效应等。 1．热效应：人体70%以上是水，水分子受到电磁波辐射后相互摩擦，引起机体升温，从而影响到体内器官的正常工作。 2．非热效应：人体的器官和组织都存在微弱的电磁场，它们是稳定和有序的，一旦受到外界电磁场的干扰，处于平衡状态的微弱电磁场即将遭到破坏，人体也会遭受损伤。 3．累积效应：热效应和非热效应作用于人体后，对人体的伤害尚未来得及自我修复之前（通常所说的人体承受力---内抗力），再次受到电磁波辐射的话，其伤害程度就会发生累积，久之会成为永久性病态，危及生命。对于长期接触电磁波辐射的群体，即使功率很小，频率很低，也可能会诱发想不到的病变，应引起警惕。多种频率电磁波特别是高频波和较强的电磁场作用人体的直接后果是在不知不觉中导致人的精力和体力减退，容易产生白内障、白血病、脑肿瘤，心血管疾病、大脑机能障碍以及妇女流产和不孕等，甚至导致人类免疫机能的低下，从而引起癌症等病变。<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">到<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体"><a href="http://www.emcgarden.net/">电磁兼容(EMC)和电磁干扰(EMI)学习园地</a>( <a href="http://www.emcgarden.net/">http://www.emcgarden.net</a> )<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">学习各种电磁兼容<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体">(EMC)<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">设计整改经验知识以及各种电磁干扰<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体">(EMI)<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">解决措施，到<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体"><a href="http://www.studyemc.net/">电磁兼容(EMC)和电磁干扰(EMI)下载园地</a>( <a href="http://www.studyemc.net/">http://www.studyemc.net</a> )<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">下载各种<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体">EMC<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">标准和<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体">EMC<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">资料以及安规防雷静电放电<span lang="EN-US" style="FONT-SIZE: 10.5pt; FONT-FAMILY: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体">ESD<span style="FONT-SIZE: 10.5pt; FONT-FAMILY: 宋体; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA; mso-bidi-font-size: 12.0pt; mso-ascii-font-family: "Times New Roman"; mso-hansi-font-family: "Times New Roman"; mso-font-kerning: 1.0pt">等资料。 权威统计数字表明：经常在显示器前工作的人群中，上述疾病的发病率明显高于普通人群。电磁辐射是主要原因之一。

这么厉害，我天天使用电脑手机后果不是太可怕了！

生活中，电脑对你的干扰只是一个很小的部分。

热效应不就是微波炉原理吗
