主题：高压输电线的辐射安全问题——为后代，向西西河友求教 -- 大秦猛士
家园 FDA/FCC 的观点 The "Minimum Safe Distance" from a mobile phone base antenna is described by the Food and Drug Administration/FCC as follows: "To be exposed to levels at or near the FCC limits for cellular or PCS frequencies an individual would essentially have to remain in the main transmitted radio signal (at the height of the antenna) and within a few feet from the antenna . . . . In addition, for sector-type antennas RF levels to the side and in back are insignificant." Note that the quote about safe distances applies to the actual radiating antenna, not to the tower (or building or structure) the antenna is on. For a mobile phone base station antenna mounted on a tower that is 5+ meters high (about 15 feet), there should be no areas that will come anywhere close to the RF radiation safety guidelines, so the concept of a "minimum safe distance" doesn't really apply to generally occupied areas.

家园 Thanks! But what's the difference between the radiating antenna and the the tower the antenan is on?
家园 这个要小心喽，发射塔一般为900M左右高频， 移动通讯的辐射非工频电场所能比，人家工作的效果就靠辐射了，低了可不行
你们距离50米比较近，但如果高差大，反而“灯下黑”，切记水泥墙的衰减能力很强，如果是窗户正对着，那还是搞个能导电的窗帘，不知道那个什么防紫外线的布料是否导电，如果导电用来作防辐射窗帘就行了
家园 谢谢大家的热心帮助 我大致清楚了。
高压电对于人体的影响，看来目前就是事出有因查无实据的事情，手机辐射对人体的影响，已经跟踪研究十多年了，医学界不是还没有统一结论么。毕竟科学研究要讲证据的。
至于房价问题，因为短期内不打算卖了（LD在装修中出了大力，搬家的时候恶狠狠地说住到死都不搬了
），所以对房价的影响也就不多考虑咯，谢谢大家的提醒。觉得人的心理真是很怪的。很多有充分科学证明的东西，还敌不过自己的主观感觉。比如核电站的安全性已经得到充分证明了，可如果附近要造核电站，偶还是会惴惴的，哈哈。
