服務項目簡介:

電磁輻(fu)射，你了解多(duo)少？

電磁(ci)波(bo)與(yu)生物體間存在著復雜的(de)因(yin)果關系。近年來，有人提(ti)出外部電場與(yu)生物機(ji)體內部電場相互作用(yong)而引起危(wei)害的(de)理(li)(li)論。根據(ju)這(zhe)種理(li)(li)論，云龍(long)區電磁(ci)場檢測，很低的(de)輻(fu)射(she)水(shui)平就有可(ke)能(neng)造成人體傷(shang)害。也有人提(ti)出由于共(gong)振引起的(de)危(wei)害理(li)(li)論等。盡(jin)管如此(ci)，電磁(ci)輻(fu)射(she)中熱效應引起的(de)傷(shang)害仍(reng)然是主(zhu)要的(de)。

電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)不(bu)(bu)僅存(cun)在于真空(kong)中(zhong)，也存(cun)在于物(wu)質空(kong)間，包括生(sheng)(sheng)(sheng)物(wu)組織(zhi)。在無線電(dian)(dian)(dian)(dian)(dian)頻(pin)(pin)譜中(zhong)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)的(de)能很小，不(bu)(bu)可(ke)能改變分(fen)子結構或破(po)壞(huai)分(fen)子鍵(jian)。當無線電(dian)(dian)(dian)(dian)(dian)頻(pin)(pin)率為 300×1012Hz時(shi)，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)造成的(de)大能只(zhi)有1.2MeV（兆(zhao)電(dian)(dian)(dian)(dian)(dian)子伏）。而(er)要打斷(duan)弱的(de)氫鍵(jian)也需要80MeV。所(suo)以(yi)，頻(pin)(pin)率為300×1012Hz 及(ji)以(yi)下的(de)無線電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)波，稱為非(fei)電(dian)(dian)(dian)(dian)(dian)離(li)輻(fu)射(she)。電(dian)(dian)(dian)(dian)(dian)離(li)輻(fu)射(she)，如天然核素的(de)丙射(she)線，工頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)檢測方(fang)法，頻(pin)(pin)率一般(ban)都在1012Hz，能量大為2.6MeV。這(zhe)就是說(shuo)，甚至高強度(du)的(de)非(fei)電(dian)(dian)(dian)(dian)(dian)離(li)輻(fu)射(she)也不(bu)(bu)能在生(sheng)(sheng)(sheng)物(wu)體(ti)中(zhong)產(chan)(chan)(chan)(chan)生(sheng)(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)。（則可(ke)以(yi)產(chan)(chan)(chan)(chan)生(sheng)(sheng)(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，直(zhi)接(jie)破(po)壞(huai)生(sheng)(sheng)(sheng)物(wu)體(ti)）。但非(fei)電(dian)(dian)(dian)(dian)(dian)離(li)輻(fu)射(she)產(chan)(chan)(chan)(chan)生(sheng)(sheng)(sheng)的(de)其(qi)他生(sheng)(sheng)(sheng)物(wu)效(xiao)應(ying)(ying)，如熱、化(hua)學反應(ying)(ying)和電(dian)(dian)(dian)(dian)(dian)流在機(ji)體(ti)中(zhong)的(de)感應(ying)(ying)等(deng)，同樣(yang)可(ke)以(yi)破(po)壞(huai)生(sheng)(sheng)(sheng)物(wu)機(ji)體(ti)。這(zhe)就是電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)輻(fu)射(she)產(chan)(chan)(chan)(chan)生(sheng)(sheng)(sheng)危害的(de)機(ji)理。

工頻電磁輻射檢(jian)測簡介:

工(gong)頻(pin)電(dian)磁(ci)(ci)輻射準確的名稱(cheng)(cheng)應該(gai)是(shi)工(gong)頻(pin)電(dian)場(chang)強(qiang)(qiang)度(du)(du)及工(gong)頻(pin)磁(ci)(ci)場(chang)強(qiang)(qiang)度(du)(du)，我國規定(ding)的民用和工(gong)業用電(dian)的標準頻(pin)率定(ding)為(wei)50Hz（其他國家(jia)也有(you)60Hz的），所以(yi)(yi)50Hz被(bei)稱(cheng)(cheng)為(wei)工(gong)頻(pin)。當有(you)電(dian)流通(tong)過電(dian)線或(huo)電(dian)器設(she)備時，這些電(dian)器就會感生磁(ci)(ci)場(chang)產生，其強(qiang)(qiang)度(du)(du)會隨(sui)著電(dian)流強(qiang)(qiang)度(du)(du)的增大而增大。工(gong)頻(pin)電(dian)磁(ci)(ci)場(chang)是(shi)一種(zhong)感生磁(ci)(ci)場(chang)，單位一般以(yi)(yi)特(te)斯拉（T）計，按照，100微特(te)（μT）以(yi)(yi)下，即為(wei)相對安全范圍。

工頻電(dian)磁輻(fu)射檢(jian)測(ce)產生(sheng)來源(yuan):

變電(dian)(dian)站、發(fa)電(dian)(dian)站、配電(dian)(dian)房、高壓電(dian)(dian)線，家(jia)里的電(dian)(dian)吹風、電(dian)(dian)視機、電(dian)(dian)腦、電(dian)(dian)冰箱等電(dian)(dian)器(qi)

工頻(pin)電磁輻射檢(jian)測的危害:

環(huan)境中磁場(chang)的變動，降(jiang)低(di)褪黑的分(fen)泌，高壓(ya)電磁場(chang)檢測，并增強(qiang)腦電的覺醒作用，導致，難以(yi)入睡、夜間易覺醒。
