<韶關> 博創輻射防護工程

為了(le)減少或阻擋X射(she)線(xian)(xian)(xian)對(dui)醫護(hu)人員的損傷，X射(she)線(xian)(xian)(xian)防(fang)(fang)護(hu)服就(jiu)成了(le)為醫護(hu)工作(zuo)者的保駕護(hu)航的重(zhong)要(yao)(yao)(yao)設備(bei)。但是(shi)建(jian)議(yi)大家在使(shi)用X射(she)線(xian)(xian)(xian)防(fang)(fang)護(hu)服時需要(yao)(yao)(yao)定(ding)(ding)期檢測，原因如(ru)下(xia)：任何物品在使(shi)用一段時間都會(hui)有(you)(you)不同程(cheng)度的損壞，X射(she)線(xian)(xian)(xian)防(fang)(fang)護(hu)服作(zuo)為保障醫護(hu)工作(zuo)人員身體的重(zhong)要(yao)(yao)(yao)的防(fang)(fang)護(hu)服，更應該做好定(ding)(ding)期檢測。X射(she)線(xian)(xian)(xian)防(fang)(fang)護(hu)服應每(mei)年接(jie)受一到(dao)兩(liang)次檢查(cha)，主(zhu)要(yao)(yao)(yao)檢查(cha)X射(she)線(xian)(xian)(xian)防(fang)(fang)護(hu)服內層(ceng)材(cai)料(liao)的完(wan)整性(xing)，查(cha)看內層(ceng)材(cai)料(liao)是(shi)否有(you)(you)斷(duan)裂和漏射(she)，如(ru)有(you)(you)問(wen)題，一定(ding)(ding)要(yao)(yao)(yao)報廢(fei)。X射(she)線(xian)(xian)(xian)防(fang)(fang)護(hu)服作(zuo)為一種特(te)殊(shu)防(fang)(fang)護(hu)服飾，它是(shi)為了(le)保障醫護(hu)工作(zuo)人員身體而(er)存在的，如(ru)果(guo)出現破損、內層(ceng)斷(duan)裂和漏射(she)的情況(kuang)，就(jiu)一定(ding)(ding)要(yao)(yao)(yao)報廢(fei)。鉛衣

　射(she)(she)(she)線(xian)防護鉛(qian)(qian)(qian)(qian)(qian)(qian)衣、鉛(qian)(qian)(qian)(qian)(qian)(qian)帽自然是(shi)用(yong)于抵(di)擋(dang)x射(she)(she)(she)線(xian)對(dui)人(ren)(ren)(ren)(ren)體頭(tou)(tou)部(bu)(bu)的(de)(de)(de)傷害(hai)(hai)(hai)，頭(tou)(tou)部(bu)(bu)作為(wei)我們人(ren)(ren)(ren)(ren)體非(fei)常(chang)重(zhong)要(yao)的(de)(de)(de)部(bu)(bu)位，不(bu)允許(xu)出現(xian)(xian)任何差錯。防輻(fu)射(she)(she)(she)鉛(qian)(qian)(qian)(qian)(qian)(qian)帽適(shi)(shi)用(yong)于醫生(sheng)(sheng)、患者(zhe)，及介入時(shi)X射(she)(she)(she)線(xian)的(de)(de)(de)防護，下面(mian)我們簡單了解一(yi)下X射(she)(she)(she)線(xian)對(dui)人(ren)(ren)(ren)(ren)體的(de)(de)(de)危(wei)害(hai)(hai)(hai)！X射(she)(she)(she)線(xian)對(dui)生(sheng)(sheng)物(wu)細胞有(you)一(yi)定的(de)(de)(de)殺(sha)傷破壞(huai)作用(yong)，會造成人(ren)(ren)(ren)(ren)體部(bu)(bu)分機(ji)體細胞受到(dao)損(sun)害(hai)(hai)(hai)，受損(sun)細胞如不(bu)能(neng)(neng)自我修復(fu)，會殘存于體內，人(ren)(ren)(ren)(ren)體在(zai)(zai)抵(di)抗力低下，極(ji)有(you)可能(neng)(neng)迅速出現(xian)(xian)一(yi)個灶(zao)。過量(liang)照(zhao)射(she)(she)(she)后，還會造成組織(zhi)的(de)(de)(de)破壞(huai)，影響(xiang)生(sheng)(sheng)理機(ji)能(neng)(neng)，更甚至會引起生(sheng)(sheng)命危(wei)險(xian)。如果(guo)長時(shi)間、大劑量(liang)地受到(dao)射(she)(she)(she)線(xian)輻(fu)射(she)(she)(she)，有(you)可能(neng)(neng)導致絕(jue)育、生(sheng)(sheng)長發育遲緩，甚至誘發更惡性的(de)(de)(de)結(jie)果(guo)。防輻(fu)射(she)(she)(she)鉛(qian)(qian)(qian)(qian)(qian)(qian)帽的(de)(de)(de)作用(yong)：防輻(fu)射(she)(she)(she)鉛(qian)(qian)(qian)(qian)(qian)(qian)帽可以在(zai)(zai)減少頭(tou)(tou)部(bu)(bu)輻(fu)射(she)(she)(she)劑量(liang)的(de)(de)(de)效果(guo)是(shi)鉛(qian)(qian)(qian)(qian)(qian)(qian)擋(dang)板的(de)(de)(de)30倍。一(yi)般(ban)市場(chang)上的(de)(de)(de)鉛(qian)(qian)(qian)(qian)(qian)(qian)材質(zhi)都(dou)比較適(shi)(shi)中，鉛(qian)(qian)(qian)(qian)(qian)(qian)帽的(de)(de)(de)重(zhong)量(liang)都(dou)在(zai)(zai)1.1KG左(zuo)右，存在(zai)(zai)佩(pei)戴(dai)不(bu)適(shi)(shi)感(gan)及對(dui)頭(tou)(tou)部(bu)(bu)及頸(jing)部(bu)(bu)帶(dai)來職業(ye)和的(de)(de)(de)危(wei)害(hai)(hai)(hai)。有(you)實物(wu)證實，現(xian)(xian)在(zai)(zai)推出的(de)(de)(de)新材料無鉛(qian)(qian)(qian)(qian)(qian)(qian)材質(zhi)鉛(qian)(qian)(qian)(qian)(qian)(qian)帽，不(bu)僅(jin)可以在(zai)(zai)佩(pei)戴(dai)此(ci)種(zhong)鉛(qian)(qian)(qian)(qian)(qian)(qian)帽時(shi)能(neng)(neng)額外減少頭(tou)(tou)部(bu)(bu)輻(fu)射(she)(she)(she)劑量(liang)的(de)(de)(de)90%，并且平均重(zhong)量(liang)為(wei)200g左(zuo)右，佩(pei)戴(dai)期(qi)間不(bu)會出現(xian)(xian)不(bu)適(shi)(shi)感(gan)。即使(shi)使(shi)用(yong)時(shi)間很長，隨(sui)鉛(qian)(qian)(qian)(qian)(qian)(qian)橡膠的(de)(de)(de)自然老化也不(bu)會有(you)鉛(qian)(qian)(qian)(qian)(qian)(qian)粉游離(li)出來對(dui)周(zhou)圍環境以及人(ren)(ren)(ren)(ren)群(qun)造成鉛(qian)(qian)(qian)(qian)(qian)(qian)污染，損(sun)害(hai)(hai)(hai)。

鉛衣在(zai)實際(ji)工作中，由于(yu)條(tiao)件(jian)所限，往往單(dan)靠縮短接觸時間和增大(da)距離(li)(li)并不(bu)能達到操作的(de)目(mu)的(de)。例如(ru)室(shi)內安裝一大(da)型 60 Co輻照源(yuan)，離(li)(li)工作人(ren)員的(de)距離(li)(li)也只有幾(ji)米。在(zai)工作人(ren)員處的(de)劑(ji)(ji)量當量可(ke)能達1希/秒以上(shang)，這時即使在(zai)那里停留一秒鐘也是很危險的(de)。因此上(shang)述兩(liang)種方法都不(bu)適用(yong)，而必須采用(yong)屏(ping)蔽(bi)防護。屏(ping)蔽(bi)防護就是根據輻射(she)通過(guo)物質時被減(jian)弱的(de)原理，在(zai)人(ren)與輻射(she)源(yuan)之間加一層足夠厚的(de)屏(ping)蔽(bi)物（減(jian)弱材料(liao)），把外(wai)照射(she)劑(ji)(ji)量減(jian)少到控制(zhi)標準以下，以保護人(ren)體。
