關于基站輻射的三大誤(wu)區

誤區一：通(tong)訊(xun)基(ji)站越多，輻射就越大(da)

其實，通訊基站的輻(fu)(fu)射(she)量還沒有(you)一屋子家(jia)電(dian)輻(fu)(fu)射(she)大。地(di)球本身(shen)就是一個大磁場。在(zai)自然界，電(dian)閃雷擊、太(tai)陽黑子活動、大氣(qi)、宇(yu)宙等都在(zai)產生(sheng)電(dian)磁輻(fu)(fu)射(she)。在(zai)生(sheng)活中(zhong)，微(wei)波爐、電(dian)腦、電(dian)視機、吹風機、收音機等家(jia)用電(dian)器也會產生(sheng)電(dian)磁輻(fu)(fu)射(she)。

與這些常用(yong)家(jia)用(yong)電(dian)器相比，小(xiao)區基站的(de)輻(fu)(fu)射(she)量(liang)微(wei)乎其(qi)微(wei)。因(yin)為，通(tong)訊(xun)基站天(tian)線的(de)輻(fu)(fu)射(she)覆蓋面積(ji)較廣，輻(fu)(fu)射(she)功率分(fen)散在(zai)方(fang)圓幾平方(fang)公里的(de)面積(ji)上，而(er)且與人(ren)(ren)體的(de)距(ju)離(li)往往超過 10 米，工(gong)頻(pin)電(dian)磁場(chang)輻(fu)(fu)射(she)檢測，對人(ren)(ren)體的(de)影響較小(xiao)。

筆(bi)記(ji)本電腦、手機等(deng)雖然(ran)自身發射(she)功率不及(ji)通訊(xun)基站(zhan)天線，但往(wang)往(wang)是與人體零距離(li)接觸，所以輻射(she)值反而更大。
