答：任何電(dian)(dian)(dian)器使用(yong)都(dou)會有(you)電(dian)(dian)(dian)磁場(chang)，家里敷設的(de)(de)電(dian)(dian)(dian)源線也有(you)電(dian)(dian)(dian)磁場(chang)，人們生(sheng)活在地球上其(qi)實(shi)就是(shi)一個大磁場(chang)。這(zhe)就要看電(dian)(dian)(dian)磁場(chang)的(de)(de)強(qiang)度(du)(du)有(you)多大才對人體(ti)有(you)害(hai)，國家規定(ding)：正常使用(yong)情(qing)況下，電(dian)(dian)(dian)磁輻射電(dian)(dian)(dian)場(chang)強(qiang)度(du)(du)值4000V/M。磁感應(ying)強(qiang)度(du)(du)值100UT以下均對人體(ti)沒(mei)有(you)損害(hai)。安(an)徽中(zhong)拓發熱(re)電(dian)(dian)(dian)纜(lan)(lan)設有(you)屏蔽(bi)(bi)接(jie)地保護，將電(dian)(dian)(dian)磁場(chang)屏蔽(bi)(bi)在電(dian)(dian)(dian)纜(lan)(lan)芯線內(nei)引入(ru)大地。經檢(jian)測，安(an)徽中(zhong)拓發熱(re)電(dian)(dian)(dian)纜(lan)(lan)所(suo)產(chan)生(sheng)的(de)(de)電(dian)(dian)(dian)磁場(chang)，其(qi)電(dian)(dian)(dian)場(chang)強(qiang)度(du)(du)值最高為4.12V/㎡，是(shi)國家安(an)全(quan)值的(de)(de)13.8%，遠遠低于國家標準，通過美國聯(lian)邦BACL電(dian)(dian)(dian)纜(lan)(lan)輻射安(an)全(quan)（EMC）R認證，所(suo)以對人體(ti)沒(mei)有(you)傷害(hai)，非常安(an)全(quan)。
