I don't think the nicotine in a cigarette is going to "calm richards'
condition." Perhaps some Thorazine would help, but that is only by prescription ... "getting laid" has always helped me ... GRIN Regards, JS I should think there would be health risks from "getting laid" face down in the mud. |

While the hand feeling could easily be attributed to the battery discharge warmth, the feeling around the ears is more difficult to ascribe to the batteries. Umm... many cell phones get noticeably warm over time due to internal power dissipation. (In fact, the amount of heat generated by the battery is negligible compared to the heat generator by, e.g., the RF power amplifiers, the digital circuitry, etc.) Strange, I could have said just that!. Oh wait, I did. Look, it is easy for a person's hand to get warm and attribute it to battery warmth. I trust you are not ascribing the same for an area that the phone isn't touching? That is easy to check for, as the hand would be heated by conduction, and the area around the ear that isn't being touched would be radiative heat. Other wise there would be a significant thermal gradient. How many studies have been done looking for beneficial health outcomes from the use of cell phones? Probably none. The reason why is that the studies are looking for effect in general, not positive or negative ones. To look for a specific positive or negative from the start is more in line with creation science. Like wine and alcohol in moderation are now considered to be! It is easy to find out the effects of alcohol. Lots of studies. And they found out a lot of things they didn't expect, such as keeping the blood vessels clean, and other more obvious things such as stress relief/relaxation in moderation. I'm certain that if some positive result is found, we'll hear about it. - 73 de Mike N3LI - When "it" gets hot pop the battery off - now, which is hot the battery or the phone? Dave |

Now I have this video stuck in my head of you sniffing the output of trees at twilight. ;-) Dave K8MN |

But we need to remember that experiments only become valid when repeated numerous times. As these are only summaries, they are hard to compare and we loose that without having the full experiment laid out before us. I have tended to throw away those that didn't describe the frequency and field strength in some way as less than anecdotal. I'm still not convinced that use of tobacco products are bad for you, and I've got scientific evidence from tobacco industry lawyers to back me up. ;^) No relation to this issue except there are people who stand to profit by both being harmless. There is always the question of how many studies it takes to make something "real". I always like to mention the book from the 1870's that mentions how smoking causes lung cancer; chewing causes oral cancer. But it wasn't until almost a hundred years later that it really did, because it took that long to be "proven". All we can do is make an informed guess, and stick with it. I choose to limit my cell phone use. - 73 de Mike N3LI - One way to tell is by looking around you to see how those around you are being affected. Perhaps the MEDIA causes the most brain damage on the planet by spreading madness on grand scales. I'vve always thought we get the media we deserve..... I can point to a whole lot of people who WERE harmed in so many ways by Tobacco products. I can only point to ONE who has been harmed by RF. The guy leaned up against an inverted V and grabbed on to it. Probably 5kw and it killed a line in his palm. It did completely heal though. Ouch! I was hit once with about 50 watts. One of my first antennas was a random wire, and RF was coupled to the metal ring around the tuning cap on my matchbox. Hurt something awful, put a hole in my finger, and there was even a little smoke. That guy must have really hurt. Who was it here that told about birds landing on ladder line and getting zapped. leaving only their feet wrapped around the line? Still I wouldn't consider a ban on either, as long as the user can keep it from costing or endangering me. Don't forget there is a political agenda to do away with a lot of things. The RF hazard thing is based on a minor risk blown out of proportion by those whose million dollar views were spoiled by transmitter sites. Well, that is one of the reasons. We sometimes tend to focus pretty narrowly. That some of these folk don't like much of anything is pretty spot on. But we shouldn't carry that over as blanket condemnation. Its like blaming the little old lady sitting at home drinking her sherry with binge drinking college students. If it weren't for well funded environmental lobbyists, the FCC wouldn't have been pressured into cutting exposure limits to half from what was learned by military studies in the 40's to the 60's and established in the 70's and cut to half of that in the 80's and finally made into law for hams and cut in half again for nervous people who still can't point to anything more concrete than the old military studies. There have been lots of studies since then. Those same people had oil production cut in this country so that now you have to pay $4 a gallon. The supply/demand effects of our oil production via offshore, or unused interior drilling, are not responsible for the prices we are paying now. There is a combination of massive demand by the developing countries, large demand by ourselves, and rampant speculation. There is also the issue of we really only have so much oil. And we've used most of it (unless you ascribe to the abiotic oil theory) Don't discount the possibility of sitting on reserves. In our area, there were gas and oil wells drilled between 25 years ago, and the present. Most of them sat, some to the point of needing new caps put on the wells because the old ones got rusty. But there are many hundreds, perhaps thousands of wells there. As we speak, there are new pipelines being put in to bring the stuff to market. Simply when the price became right, the supply was "uncorked". And it looks like there is a lot of it. More gas than oil, but still significant. Not a liberal or a tree hugger in the mix. Just good old supply and demand. You want to point fingers? There has been a bubble of shady speculation running through the business world. A few years back, it was the Dot.com bubble. then it was the criminally innovative accounting practices that burst Enron and World.com into the news. Then it was the real estate issue, with loans so bad that some of these people were folding back their interest payments into their principal. That is insanity. How on earth could such a thing be allowed or legal? But the people originating the loans had not reason not to. They got their commission, and the loan was immediately sold to some other institution, who would then play a game of "hot potato", whoever was holding the mortgage when it defaulted was the loser. Interesting that the gasoline prices went haywire so soon after the real estate markets collapsed. These folk (a very loose aggregation, but certainly a trend) just moved from one form of speculation to another. Speculation is and should be a good thing, allowing money to be put into risky and unproven fields. But it can be taken too far. See the above. BTW I don't even own a cell phone. I have had them but they are too much of a distraction. I'd rather not, but I have to.. 8^( - 73 de Mike N3LI - |

There have been lots of studies since then. I would suggest taking a look at the latest IEEE/ANSI standard for exposure. The actual limits in the standard only take a few pages. The other 100 pages is the critical analysis of the hundreds of studies with respect to every effect one can imagine, and then some. As Michael points out, there's been a LOT of studies in the last few years (driving, for instance, a change from field strength limits to SAR limits in some cases) What the standard and accompanying analysis makes very clear, though, is that there is no way to "prove a negative": i.e. there is no way to "prove" that a particular EM field exposure doesn't have any long term effects. All you can do is say that there is no known mechanism by which such an effect can be produced, or that if it does exist, there's no way to measure it in a statistically significant way, or, in some cases, that greater exposures have been shown experimentally to have no moderate term effects (e.g. nobody's done a longitudinal study lasting 30-40 years that's been controlled for other confounding effects). What you CAN say is that the studies prompting the early alarmist literature (e.g. "currents of death", "VDTs cause miscarriage") have severe methodological or statistical problems. Unfortunately, those early studies have been (poorly) abstracted and summarized many times and the caveats in the original paper, or subsequent better studies, are ignored. Particularly in non-technical trade literature (e.g. trade magazines aimed at, for example, small business owners), the author of an article writing about minimizing hazards in the workplace might not actually know very much about the details of the hazards, nor do a whole lot of research beyond what's in Wikipedia or copied from some other trade magazine. They certainly don't go back to the original source, nor do they look at current standards, etc. I still run across articles that (indirectly) cite the famous (and totally misinterpreted) Kaiser VDT study from 1981/1982, published in 1988. While that study found a correlation, one has to remember correlation is not causation. Someone googling VDT and miscarriage will no doubt turn up articles in the NY Times from 1988, for instance, but not pay attention to the fact that the article is 20 years old, because, on the web, the date is tiny print and grey. |
