现在人们经常使用电子设备,比如手机不离身,上班长时间使用电脑、打印机等,或多或少都有有一定的辐射，不过很多用户都不清楚电脑辐射范围有多少米，今天，小编就把电脑辐射范围介绍给大家，我们一起来看看吧。
工具/原料：
1、操作系统： windows 7 windows 10
2、品牌型号：台式/笔记本电脑
3、：软件版本：小白一键重装系统 12.6.49.2290 下载地址：http://www.01xitong.com/
具体内容
其中键盘1000V/m.鼠标450V/m.屏幕218V/m.主机170V/m.Notebook2500V/m 依国际MPRⅡ防辐射安全规定：在50cm距离内必须小于等于25V/m的辐射暴露量。
其次电脑电磁辐射分两个级别，其中工频段的单位是μT，如果电脑辐射在0.4μ T以上属于较强辐射，对人体有一定危害，长期接触易患白血病。如果电脑辐射在0.4μT以下，相对安全。而射频电磁波的单位是μW/㎝ 2。而且人们一直认为传统CRT显示器的辐射较大，到底是不是大家认为的那样呢?有资料对传统CRT显示器进行测试，显示器只要保持 0.2米的距离就可以放心使用。传统CRT显示器的辐射指数是三级。
如今液晶显示器正替代传统显示器，那么笔记本电脑辐射大吗?笔记本电脑辐射范围是多少米?资料显示对它进行了测试。笔记本电脑显示屏前 0.5米0.11μT，开机瞬间0.12μT，关机0.11μT，显示屏侧面 0.5米0.12μT，看来笔记本电脑液晶显示器还真是挺让人放心的。液晶显示器的辐射指数是一级。
然后资料显示测试出笔记本电脑显示屏前0.1米0.13μT，显示屏前 0.3米0.10μT，显示屏侧面0.3米0.13μT，键盘上方0.19 μT，电源适配器0.22μT。测试结果显示笔记本键盘辐射稍强，电源适配器最大。笔记本电脑辐射指数是一级。
最后友情提示：液晶显示屏的辐射很小，CRT显示器略大一些，但都在安全范围。主机后面、侧面辐射较大，强烈建议您不要为了散热方便，敞开机箱使用。低音炮音箱辐射严重，使用时至少保持半米距离。笔记本辐射集中在键盘上方，使用笔记本时应与电源适配器保持远一点的距离。
以上就是今天小编给大家分享的全部内容，希望能帮到大家。
