問 我們(men)辦(ban)公室里人手(shou)一臺電腦(nao)(nao)，聽說電腦(nao)(nao)的輻射對身(shen)體有害，如何減(jian)少電腦(nao)(nao)輻射對身(shen)體的危害？

答 1.避免長時間(jian)連(lian)續操(cao)作(zuo)電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)，注(zhu)意中間(jian)休息。要(yao)保(bao)持(chi)一(yi)個最(zui)適當的(de)(de)(de)姿勢，眼(yan)睛與屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)的(de)(de)(de)距(ju)離應(ying)在(zai)40~50厘米，使(shi)(shi)雙眼(yan)平(ping)視(shi)或(huo)(huo)輕度(du)向下(xia)注(zhu)視(shi)熒(ying)光(guang)屏(ping)(ping)(ping)(ping); 　　 2.室(shi)內要(yao)保(bao)持(chi)良好的(de)(de)(de)工(gong)作(zuo)環境，如(ru)舒適的(de)(de)(de)溫度(du)、清(qing)潔的(de)(de)(de)空氣(qi)、合(he)適的(de)(de)(de)陰離子濃度(du)和(he)臭(chou)氧濃度(du)等(deng)(deng); 　　 3.電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)室(shi)內光(guang)線(xian)要(yao)適宜(yi)，不(bu)(bu)可(ke)過(guo)亮或(huo)(huo)過(guo)暗，避免光(guang)線(xian)直接照射在(zai)熒(ying)光(guang)屏(ping)(ping)(ping)(ping)上而產生干擾光(guang)線(xian)。工(gong)作(zuo)室(shi)要(yao)保(bao)持(chi)通(tong)風干爽(shuang); 　　 4.電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)的(de)(de)(de)熒(ying)光(guang)屏(ping)(ping)(ping)(ping)上要(yao)使(shi)(shi)用(yong)濾色(se)鏡，以(yi)減輕視(shi)疲(pi)勞。最(zui)好使(shi)(shi)用(yong)玻璃或(huo)(huo)高質量的(de)(de)(de)塑料(liao)濾光(guang)器; 　　 5.安裝防(fang)護裝置(zhi)(zhi)，比如(ru)貼(tie)防(fang)輻(fu)(fu)射的(de)(de)(de)屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)保(bao)護膜，削弱電(dian)(dian)(dian)(dian)(dian)磁(ci)輻(fu)(fu)射的(de)(de)(de)強度(du)。 像防(fang)輻(fu)(fu)射的(de)(de)(de)屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)貼(tie)膜里面(mian)添加(jia)了(le)納米金屬層，來有效降低電(dian)(dian)(dian)(dian)(dian)磁(ci)波和(he)紫外線(xian)的(de)(de)(de)通(tong)過(guo); 　　 6.注(zhu)意保(bao)持(chi)皮(pi)(pi)膚(fu)清(qing)潔。電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)熒(ying)光(guang)屏(ping)(ping)(ping)(ping)表面(mian)存在(zai)著大量靜(jing)電(dian)(dian)(dian)(dian)(dian)，其(qi)集聚的(de)(de)(de)灰塵可(ke)轉射到臉部和(he)手部皮(pi)(pi)膚(fu)裸露(lu)處，時間(jian)久了(le)，易(yi)發生斑疹、色(se)素(su)沉著，嚴重(zhong)者甚至會引起皮(pi)(pi)膚(fu)病變等(deng)(deng); 　　 7.注(zhu)意補(bu)充(chong)(chong)營(ying)養。電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)操(cao)作(zuo)者在(zai)熒(ying)光(guang)屏(ping)(ping)(ping)(ping)前工(gong)作(zuo)時間(jian)過(guo)長，視(shi)網膜上的(de)(de)(de)視(shi)紫紅質會被消耗掉(diao)，而視(shi)紫紅質主要(yao)由維生素(su)A合(he)成。因此，電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)操(cao)作(zuo)者應(ying)多(duo)(duo)吃些(xie)胡蘿卜(bu)、白(bai)菜(cai)、豆(dou)芽、豆(dou)腐、紅棗、橘子以(yi)及牛奶、雞蛋、動(dong)物肝(gan)臟、黃(huang)滑松茸，瘦肉(rou)等(deng)(deng)食物，以(yi)補(bu)充(chong)(chong)人體內維生素(su)A和(he)蛋白(bai)質。而多(duo)(duo)飲些(xie)茶，茶葉(xie)中的(de)(de)(de)茶多(duo)(duo)酚等(deng)(deng)活性(xing)物質會有利于吸收與抵抗放射性(xing)物質;　　 8.應(ying)盡可(ke)能(neng)購買新款(kuan)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)，一(yi)般(ban)不(bu)(bu)要(yao)使(shi)(shi)用(yong)舊(jiu)電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)，舊(jiu)電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)的(de)(de)(de)輻(fu)(fu)射一(yi)般(ban)較(jiao)厲(li)害，在(zai)同距(ju)離、同類機型的(de)(de)(de)條件下(xia)，一(yi)般(ban)是(shi)新電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)的(de)(de)(de)1－2倍; 　　 9.電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)擺放位置(zhi)(zhi)很(hen)重(zhong)要(yao)。盡量別(bie)讓(rang)屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)的(de)(de)(de)背面(mian)朝著有人的(de)(de)(de)地方，因為電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)輻(fu)(fu)射最(zui)強的(de)(de)(de)是(shi)背面(mian)，其(qi)次為左右兩側(ce)，屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)的(de)(de)(de)正面(mian)反而輻(fu)(fu)射最(zui)弱; 　　 10.使(shi)(shi)用(yong)電(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)(nao)時，要(yao)調整好屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)的(de)(de)(de)亮度(du)，一(yi)般(ban)來說，屏(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)亮度(du)越(yue)大，電(dian)(dian)(dian)(dian)(dian)磁(ci)輻(fu)(fu)射越(yue)強，反之越(yue)小(xiao)。不(bu)(bu)過(guo)，也(ye)不(bu)(bu)能(neng)調得太(tai)暗，以(yi)免因亮度(du)太(tai)小(xiao)而影(ying)響效果，且易(yi)造成眼(yan)睛疲(pi)勞。
