I became concerned about the dangers of cell phones when that industry appeared to hire the Junk Science Propagandists to defend their corporate science several years ago. This is the same Disinformation Service the silicone industry and the dioxin industry hired to turn real science into "junk" and call industry "science" sound. Since then ... I use cell phones only for the quickest of communiques .... and recommend others I love do the same. |

in brief--towards people, obviously. I am touched you have such faith in
them giving a toss, especially when they put them next to schools, and even on top of schools "CWatters" wrote in message ... "john" wrote in message ... "D. C. Sessions" wrote in message ... What direction are cell phone panels pointing and radiating then? It depends on where the mast is and the area the company needs that mast to cover. If you had a mast in the middle of a circular village then it might need to radiate in all directions. If the mast was on the edge of the village the signal might need to be stronger on one side. A mast next to a freeway in the middle of a huge desert would be designed to radiate radiate in the two directions of the freeway on;y - no point in providing coverage in other directions! That's all a gross simplification but you get the idea. |

However, John thinks that cell phones are involved in mind control. I'm not sure why this bothers him so much, as he's perfectly safe, having no mind. -- David Wright :: alphabeta at prodigy.net These are my opinions only, but they're almost always correct.

... "john" wrote in message ... http://www.whale.to/a/micro_children.h Thanks for the laugh. Actually, if the cell phone towers were a threat to kids, being under a mast would be the place to be. The radio signals are directed outward, and not down. So there is almost no microwave energy reaching the poeple near the towers. The radio waves disperse in a 'cone' shape, so you are right in that sense that standing right under the tower in theory would give the lowest exposure. You try taking a meter and measuring the field intensity as you walk along the ground plane and you will find that it peaks close to the transmitter then falls off, then peaks again. A kids playground might be inside these peaks or houses or whatever. http://pages.britishlibrary.net/oran...sestations.htm Of course, there is also no danger from the cell phone towers at all. So we are told. But, this lack of understanding of the technology and science involved is consistant with the whaleto site, which is the laughing stock of the internet. Clearly, the author has no clue about what he says or science or medicine. No wonder she is too ashamed to put her name on it. jeff Anth |

That means 100 ft from the source the RF is 1/100(squared) less or 1/10000 less at that distance. to your notion of "peaks" those can easily be caused by interference, sort of like when you were a kid and threw two stones in a calm pond. The waves from both collide and in one place add to each other and others, totally cancel out. It's just the laws of physics at work. However, Cell towers have some 500 watts input to each antenna on the mast. I wouldn't want kids within some 150-200 ft from them either. There is some emperical evidence that RF from cell towers and phones causes changes in the blood brain barrier. That said while there are lots of studies, none replicate the results of any other so things, at present, are unproven. And please don't talk about the salford study which is flawed. What it means is that more scientific study by independent researchers is needed, that is not funded by any industry. -- Thanks, Ham |

This is true, however you rarely have one source, usually it's an antenna array, so the k/d^2 law applies loosely here as illustrated in the diagrams I posted.. Also with additive ray interference you could 'troughs and peaks'. That means 100 ft from the source the RF is 1/100(squared) less or 1/10000 less at that distance. to your notion of "peaks" those can easily be caused by interference, sort of like when you were a kid and threw two stones in a calm pond.

That said while there are lots of studies, none replicate the results of any other so things, at present, are unproven. And please don't talk about the salford study which is flawed. The article I posted there was references to possible health effects from EM masts. I find it interesting that there's articles on the effects of EM radiation on nematode worms; the information is posted in a positive manner - it makes them reproduce quicker, on the other hand the not so positive information doesn't get such a favourable news slice.. What it means is that more scientific study by independent researchers is needed, that is not funded by any industry. Yup. -- Thanks, Ham Would you not say the arguments posted here are an over simplification on what happens in the real world? (I see arguments for the k/d^2 rule when in fact this doesn't generally apply.) Anth |

"Bob Brogan" wrote in message ... (...) Radio waves propagate in a circular fashion Yes. And to be in this circle, you have to use a ladder. A big latter. The energy is not dspersed with the same energy in all directions. More energy is directed outward than downward. There are also scrict limits on the strength of the signal on the ground. http://www.fda.gov/cellphones/qa.html#8 |
