在对一般环境的电磁辐射分析中，应主要选用《环境电磁波卫生标准》主要选用《环境电磁波卫生标准》(GB9175-88)，根据辐射源的主要辐射频率，参照表2，找到其辐射强度限值。注意掌握三个标准限值，一般我们把居民居住的环境按一级安全区处理，则其标准限值为：在长、中、短波，电场强度应小于10V/m；在超短波段，电场强度应小于5V/m；在微波波段，其辐射功率密度应小于10μW/cm2。考虑到对在电磁辐射环境内工作人员的保护，我们建议在职业安全卫生领域，采用《电磁辐射防护规定》(GB8702-88)的相应限值。 将测试结果与国标对照后，如果发现测试结果超过国标限值，应考虑采取防护措施。首先应该考虑在辐射源的设备上采取措施，尽可能将其辐射值降低至国标限值之下。如果因为条件所限，无法降低辐射源周围的电磁场强度，而作业人员又必须在此环境下工作，或其它人员必须在此环境下生活，则对这些人员应该采取个体防护措施。 2．<a name="根据测试结果选用电磁个体防护设备">根据测试结果选用电磁个体防护设备</a>    随着人们物质文化水平的不断提高，各种家用电器：彩电、录像机、VCD、家用电脑、微波炉、电磁炉、无绳电话、手机等相继进入千家万户，这些家用电器和电子设备在使用过程中都会向环境空间发射与漏泄一定强度的电磁波，电磁辐射已成为继水污染、大气污染、噪声污染之后当今人们生活中的第四大污染。因此，许多研究机构和生产厂家都在相继研究开发防电磁辐射的民用产品，以减少电磁辐射对人类健康的危害。现在看来，穿着防电磁辐射的服装是比较方便有效的方法。到<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> )学习各种电磁兼容(EMC)设计整改经验知识以及各种电磁干扰(EMI)解决措施，到<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> )下载各种EMC标准和EMC资料以及安规防雷静电放电ESD等资料。一般来说，作业人员所处环境的电磁场强度超过国标限值或者作业人员所处环境的电磁场强度未超过国标限值，但与此限值比较接近，而作业人员又需要长时间在此环境工作时，都应考虑采用辐射防护用品。选用个体防护产品时，应首先确定电磁辐射的衰减度，然后，参照各种产品说明中对电磁波的衰减参数，确定使用何种形式的防护用品。降低电磁辐射方面的个体防护用品主要包括防护服装、防护眼镜及辐射防护屏。目前国内已经开发出多种面料的防护服装。防护服装中有：防护衬衫，防护围裙，防护马甲，防护大褂，护胎宝，孕妇裙，夹克套装等，此外还有用于设备屏蔽的屏蔽布等。表3列出了常用的电磁辐射方面的个体防护产品、制成材料及屏蔽效能。 防护服装是根据屏蔽或吸收原理制作的。防护眼镜是用于保护操作人员的眼镜免受伤害，对于防护眼镜的要求是：透视度要足够高，不影响视线；屏蔽效果要好（原则上应保证屏蔽后场强控制在国标限值之下）；重量轻，镜面启动灵活。防护眼镜的基本材料是金属网或金属膜。 表3 常用电磁辐射个体防护产品<table style="BORDER-RIGHT: medium none;
