當時鏤花開賣，我途徑那裏，中介告訴我要拆電塔。我在論壇裏發了了帖子，大家也不信，還有人說我賣鏤花的。桑心

1:高压线埋地下，辐射在土壤中衰减极快，减弱速度大大超过空气
2:看不到高压线很多人根本不知道这还有高压 ...

行业里面的说法是 ＵＧ的辐射比ＯＨＬ要大

Electric and magnetic fields

Electric magnetic fields (EMF) are generally higher directly over
an underground installation (the earth does not provide shielding)
and directly under an overhead installation. Magnetic fields tend to
decrease more rapidly with distance from underground installations
compared to overhead lines.

另外还有

Are Underground Power Lines Safer? The EMFs from underground powerlines are slightly different. The electric fields will usually be negligible because they are screened by soil, concrete, sand etc. But because underground cables tend to be buried close to the surface the magnetic fields at ground level are often very high, higher than from overhead cables because they are closer to you. But the EMFs fall off more rapidly than those from overhead wires because the cables are closer together and they cancel out each other’s effects more effectively. - See more at: http://www.electricsense.com/463 ... thash.tgnfWHGG.dpuf

上面两段话的内容刚好相反

所以这事还不好说

恭喜恭喜
