這個算高壓電塔嗎? 還是一般小電塔? 50公尺內, 會有電磁波影響嗎?

可以請您再解釋清楚一點嗎? 關於顏色跟飛機航道的關係?

對人可能有害的是 "高頻電磁波" 手機的是900MHZ,1800MHZ, 3G 是 3000MHZ(好像是)...
愈高頻, 愈容易發射(天線長度較短)

而輸配電 是 60HZ, 要散射出電磁波要很長的天線, 再加上電塔本身的接地效果,

逸出相當有限, 反而是磁場較強(因電流較強),

高壓會產生電場,但又因為是交流電, 對人的影響也不太...

其實還是有一點不肯定,小心為妙.
以下引文由澳洲來:

http://www.epa.sa.gov.au/powerlines.html#hazard

...However, in 2001, after reviewing all the relevant research, both the International Agency for Research on Cancer (IARC) and a UK expert group on non-ionising radiation concluded that exposure to prolonged and relatively high levels of magnetic fields may increase the risk of leukaemia in children.

Specifically, children with average daily exposures of more than 0.3 to 0.4 uT were found to have a leukaemia(=白血病) risk of 2 in 20,000 per year, whereas children with lower exposures had a risk of 1 in 20,000.

On the basis of the research findings, IARC classified magnetic fields as 'possibly carcinogenic', a classification shared with coffee, pickled vegetables, bitumen, engine exhaust and hundreds of other substances.

因此WHO鼓吹少暴露在高壓電纜下.

整個電塔都是紅 白相間的 代表這個電塔在飛機飛的航道下

整個都是紅的 代表這是在上紅丹漆(保護漆)


雙子貓大大說的沒錯


請先清楚電磁場、電磁波、游離輻射這幾種的差別。

原來還有這些事...

受教了, 謝謝.
