　　鉛門(men)教你怎樣(yang)減弱對的(de)(de)(de)(de)危害(hai)，專家表示，盡管對的(de)(de)(de)(de)危害(hai)依然有待研究(jiu)，但有些可(ke)(ke)以(yi)幫助人們遠(yuan)離(li)輻(fu)(fu)射，包(bao)括：除非(fei)必(bi)要，鉛門(men)提(ti)醒應(ying)(ying)使(shi)(shi)兒童(tong)遠(yuan)離(li)。兒童(tong)或(huo)胎兒的(de)(de)(de)(de)尚處于(yu)生(sheng)長發(fa)育(yu)階段，容易受到(dao)電(dian)磁(ci)(ci)場(chang)的(de)(de)(de)(de)損(sun)害(hai)。 　　在通(tong)話時(shi)盡量(liang)使(shi)(shi)遠(yuan)離(li)身(shen)體。電(dian)磁(ci)(ci)場(chang)的(de)(de)(de)(de)振幅會在距離(li)兩(liang)英寸處減弱至四分之(zhi)(zhi)一，在三英尺(chi)處僅(jin)為(wei)原來的(de)(de)(de)(de)五十分之(zhi)(zhi)一。盡可(ke)(ke)能使(shi)(shi)用(yong)揚聲器(qi)模(mo)式或(huo)無線藍牙(ya)耳(er)機，這可(ke)(ke)使(shi)(shi)普(pu)通(tong)的(de)(de)(de)(de)電(dian)磁(ci)(ci)輻(fu)(fu)射降(jiang)至原來的(de)(de)(de)(de)百分之(zhi)(zhi)一以(yi)下。使(shi)(shi)用(yong)免(mian)提(ti)耳(er)掛亦可(ke)(ke)以(yi)起到(dao)類(lei)似的(de)(de)(de)(de)效果(guo)(guo)。 　　避免(mian)在公共(gong)汽車等處使(shi)(shi)用(yong)，以(yi)免(mian)使(shi)(shi)輻(fu)(fu)射殃及(ji)他人。盡量(liang)不要時(shi)刻隨(sui)身(shen)攜(xie)帶。不要在夜間(jian)將放(fang)在身(shen)體附近，如枕(zhen)頭下或(huo)床頭，孕婦尤(you)其(qi)應(ying)(ying)當小(xiao)心。或(huo)可(ke)(ke)將調(diao)至“離(li)線”模(mo)式以(yi)中止電(dian)磁(ci)(ci)輻(fu)(fu)射。如果(guo)(guo)有必(bi)要隨(sui)身(shen)攜(xie)帶，請(qing)確盤朝向(xiang)(xiang)，背(bei)面(mian)朝向(xiang)(xiang)外部，從而避免(mian)電(dian)磁(ci)(ci)波穿(chuan)過。 　　的(de)(de)(de)(de)通(tong)話時(shi)間(jian)控制在數(shu)分鐘(zhong)為(wei)佳，因為(wei)輻(fu)(fu)射的(de)(de)(de)(de)生(sheng)物效應(ying)(ying)與其(qi)時(shi)間(jian)密切(qie)相關。當通(tong)話時(shi)間(jian)較長時(shi)，使(shi)(shi)用(yong)有線而不是無繩，后者的(de)(de)(de)(de)電(dian)磁(ci)(ci)發(fa)射與相似。在用(yong)通(tong)話時(shi)應(ying)(ying)當不時(shi)將換到(dao)腦部另一側(ce)，這樣(yang)可(ke)(ke)以(yi)起到(dao)分散輻(fu)(fu)射的(de)(de)(de)(de)效果(guo)(guo)。

　　鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)在領(ling)域又稱X射(she)線(xian)鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)板(ban)(ban)(ban)(ban)(ban)，鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)主(zhu)要(yao)(yao)分為(wei)(wei)國(guo)產(chan)(chan)鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)和進(jin)口(kou)鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)，主(zhu)要(yao)(yao)用作診斷X射(she)線(xian)機房(fang)、CT、ECT、PET、CT-PET等(deng)機房(fang)以(yi)及X射(she)線(xian)攝影(ying)防(fang)(fang)護室、防(fang)(fang)護門(men)(men)防(fang)(fang)護屏上的(de)觀察窗(chuang)，以(yi)及核(he)用操作防(fang)(fang)護屏等(deng)。 　　2014-2018年(nian)高鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)行業(ye)市場前瞻與投資規劃分析報告(gao)對高鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)產(chan)(chan)品的(de)市場環境、生產(chan)(chan)經營(ying)、供需渠道、企(qi)業(ye)競爭、市場價格影(ying)響(xiang)、產(chan)(chan)品進(jin)出口(kou)、行業(ye)投資環境以(yi)及可發展等(deng)問(wen)題進(jin)行了詳實系統地(di)分析和。 　　1952～1993年(nian)，共生產(chan)(chan)鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)37918噸，年(nian)產(chan)(chan)量是1978年(nian)的(de)1604.3噸。鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)的(de)主(zhu)要(yao)(yao)常用厚(hou)度(du)規格有(you)5mm、10mm、15mm、20mm，主(zhu)要(yao)(yao)的(de)生產(chan)(chan)基(ji)(ji)地(di)主(zhu)要(yao)(yao)集中在華(hua)北與華(hua)中一帶。國(guo)內主(zhu)要(yao)(yao)有(you)三個(ge)主(zhu)要(yao)(yao)生產(chan)(chan)基(ji)(ji)地(di)。鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)優(you)點很多如：強韌(ren)耐用，力學特(te)性(xing)和熱學特(te)性(xing)大致上與丙烯相同，耐沖擊性(xing)也極(ji)大為(wei)(wei)優(you)越。 　　鉛(qian)(qian)門(men)(men)的(de)種(zhong)類，門(men)(men)分有(you)多種(zhong)類型多種(zhong)叫法：鉛(qian)(qian)門(men)(men)、鉛(qian)(qian)板(ban)(ban)(ban)(ban)(ban)門(men)(men)、鉛(qian)(qian)門(men)(men)、射(she)線(xian)防(fang)(fang)護門(men)(men)、射(she)線(xian)屏蔽門(men)(men)、分為(wei)(wei)手動平開(kai)式、電動推拉(la)式。上虞市鉛(qian)(qian)門(men)(men)的(de)重要(yao)(yao)作用分析什么(me)是鉛(qian)(qian)門(men)(men)。
