問 我們(men)辦公室(shi)里人手一臺電(dian)腦(nao)，聽說電(dian)腦(nao)的輻射對(dui)身體(ti)有害(hai)，如何減少(shao)電(dian)腦(nao)輻射對(dui)身體(ti)的危害(hai)？

答(da) 1.避免長(chang)時間(jian)連續操作電(dian)(dian)(dian)(dian)腦(nao)，注意(yi)(yi)(yi)中(zhong)間(jian)休息。要(yao)保(bao)持一(yi)個最(zui)適當的(de)(de)(de)(de)(de)姿(zi)勢，眼睛(jing)(jing)與屏(ping)(ping)(ping)幕(mu)的(de)(de)(de)(de)(de)距(ju)離應在(zai)40~50厘米，使雙(shuang)眼平視(shi)(shi)或輕(qing)度向下(xia)注視(shi)(shi)熒(ying)光(guang)(guang)(guang)(guang)(guang)(guang)(guang)屏(ping)(ping)(ping); 　　 2.室內要(yao)保(bao)持良好的(de)(de)(de)(de)(de)工作環(huan)境，如(ru)舒適的(de)(de)(de)(de)(de)溫度、清潔的(de)(de)(de)(de)(de)空氣(qi)、合適的(de)(de)(de)(de)(de)陰離子(zi)濃度和臭氧濃度等(deng); 　　 3.電(dian)(dian)(dian)(dian)腦(nao)室內光(guang)(guang)(guang)(guang)(guang)(guang)(guang)線要(yao)適宜，不(bu)(bu)可過(guo)亮或過(guo)暗，避免光(guang)(guang)(guang)(guang)(guang)(guang)(guang)線直接照射(she)(she)(she)在(zai)熒(ying)光(guang)(guang)(guang)(guang)(guang)(guang)(guang)屏(ping)(ping)(ping)上(shang)(shang)而(er)(er)產生(sheng)干(gan)擾光(guang)(guang)(guang)(guang)(guang)(guang)(guang)線。工作室要(yao)保(bao)持通(tong)風干(gan)爽; 　　 4.電(dian)(dian)(dian)(dian)腦(nao)的(de)(de)(de)(de)(de)熒(ying)光(guang)(guang)(guang)(guang)(guang)(guang)(guang)屏(ping)(ping)(ping)上(shang)(shang)要(yao)使用濾色鏡(jing)，以減輕(qing)視(shi)(shi)疲勞(lao)(lao)。最(zui)好使用玻璃或高質(zhi)(zhi)量的(de)(de)(de)(de)(de)塑料濾光(guang)(guang)(guang)(guang)(guang)(guang)(guang)器(qi); 　　 5.安(an)裝防(fang)護裝置，比如(ru)貼防(fang)輻(fu)射(she)(she)(she)的(de)(de)(de)(de)(de)屏(ping)(ping)(ping)幕(mu)保(bao)護膜，削弱(ruo)電(dian)(dian)(dian)(dian)磁(ci)輻(fu)射(she)(she)(she)的(de)(de)(de)(de)(de)強(qiang)度。 像防(fang)輻(fu)射(she)(she)(she)的(de)(de)(de)(de)(de)屏(ping)(ping)(ping)幕(mu)貼膜里面(mian)(mian)(mian)添加了納(na)米金屬層，來有效(xiao)降(jiang)低(di)電(dian)(dian)(dian)(dian)磁(ci)波(bo)和紫(zi)外(wai)線的(de)(de)(de)(de)(de)通(tong)過(guo); 　　 6.注意(yi)(yi)(yi)保(bao)持皮膚(fu)清潔。電(dian)(dian)(dian)(dian)腦(nao)熒(ying)光(guang)(guang)(guang)(guang)(guang)(guang)(guang)屏(ping)(ping)(ping)表面(mian)(mian)(mian)存在(zai)著(zhu)大量靜電(dian)(dian)(dian)(dian)，其集聚(ju)的(de)(de)(de)(de)(de)灰塵可轉射(she)(she)(she)到臉部和手(shou)部皮膚(fu)裸(luo)露處(chu)，時間(jian)久了，易(yi)發生(sheng)斑疹(zhen)、色素(su)沉著(zhu)，嚴重(zhong)者甚至會引起(qi)皮膚(fu)病(bing)變等(deng); 　　 7.注意(yi)(yi)(yi)補充營養。電(dian)(dian)(dian)(dian)腦(nao)操作者在(zai)熒(ying)光(guang)(guang)(guang)(guang)(guang)(guang)(guang)屏(ping)(ping)(ping)前(qian)工作時間(jian)過(guo)長(chang)，視(shi)(shi)網膜上(shang)(shang)的(de)(de)(de)(de)(de)視(shi)(shi)紫(zi)紅質(zhi)(zhi)會被消耗(hao)掉，而(er)(er)視(shi)(shi)紫(zi)紅質(zhi)(zhi)主要(yao)由維(wei)生(sheng)素(su)A合成(cheng)。因此(ci)，電(dian)(dian)(dian)(dian)腦(nao)操作者應多(duo)吃些胡蘿卜、白菜、豆(dou)芽(ya)、豆(dou)腐、紅棗、橘子(zi)以及牛奶、雞蛋、動物(wu)肝臟、黃滑(hua)松(song)茸，瘦肉等(deng)食物(wu)，以補充人體內維(wei)生(sheng)素(su)A和蛋白質(zhi)(zhi)。而(er)(er)多(duo)飲些茶，茶葉中(zhong)的(de)(de)(de)(de)(de)茶多(duo)酚(fen)等(deng)活性物(wu)質(zhi)(zhi)會有利于吸收與抵(di)抗放射(she)(she)(she)性物(wu)質(zhi)(zhi);　　 8.應盡可能購(gou)買新(xin)款的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)腦(nao)，一(yi)般不(bu)(bu)要(yao)使用舊(jiu)電(dian)(dian)(dian)(dian)腦(nao)，舊(jiu)電(dian)(dian)(dian)(dian)腦(nao)的(de)(de)(de)(de)(de)輻(fu)射(she)(she)(she)一(yi)般較厲害，在(zai)同距(ju)離、同類機(ji)型的(de)(de)(de)(de)(de)條(tiao)件下(xia)，一(yi)般是新(xin)電(dian)(dian)(dian)(dian)腦(nao)的(de)(de)(de)(de)(de)1－2倍(bei); 　　 9.電(dian)(dian)(dian)(dian)腦(nao)擺放位(wei)置很重(zhong)要(yao)。盡量別讓(rang)屏(ping)(ping)(ping)幕(mu)的(de)(de)(de)(de)(de)背面(mian)(mian)(mian)朝著(zhu)有人的(de)(de)(de)(de)(de)地方，因為電(dian)(dian)(dian)(dian)腦(nao)輻(fu)射(she)(she)(she)最(zui)強(qiang)的(de)(de)(de)(de)(de)是背面(mian)(mian)(mian)，其次(ci)為左右(you)兩(liang)側，屏(ping)(ping)(ping)幕(mu)的(de)(de)(de)(de)(de)正(zheng)面(mian)(mian)(mian)反(fan)而(er)(er)輻(fu)射(she)(she)(she)最(zui)弱(ruo); 　　 10.使用電(dian)(dian)(dian)(dian)腦(nao)時，要(yao)調(diao)整好屏(ping)(ping)(ping)幕(mu)的(de)(de)(de)(de)(de)亮度，一(yi)般來說，屏(ping)(ping)(ping)幕(mu)亮度越(yue)大，電(dian)(dian)(dian)(dian)磁(ci)輻(fu)射(she)(she)(she)越(yue)強(qiang)，反(fan)之越(yue)小。不(bu)(bu)過(guo)，也不(bu)(bu)能調(diao)得太(tai)暗，以免因亮度太(tai)小而(er)(er)影響效(xiao)果，且易(yi)造成(cheng)眼睛(jing)(jing)疲勞(lao)(lao)。
