One also needs to consider peak vs average effects.

The athermal effects you describe such as "photon energy" is a temperature so low that for all practical purposes could be called absolute zero. No one has suggested frost-bite induction as a source of CNS trauma. Besides, thermal effects (or athermal) are related to phononic energy. Phonon-Photon interaction is the principle you are implying, and besides myself, I doubt anyone could follow that discussion. Aside from yourself, no one here showed any capacity to either calculate a temperature rise, or test it at the bench. This leaves little room for dialog on the matter - hence the plunge into shamanism. As for the E field, a 9 volt battery clipped between the ears hardly suffices, and electroshock therapy goes a further and most obvious distance. The arguments put forward by those who cry caution beg for dramatic and catastrophic effects that are unnoticed - a contradiction on the face of it: an anticonvulsant taser wound without a mark. The lack of substantive evidence is begged off as being undetectable (the same contradiction) or too mysterious to have been thought of (which is a vanity statement). My allusion to Phonons would certainly fall into this last category, but it is an old field of established study that is rare, not unknown. I've calibrated defibrillators and worked with peak energy delivery systems from millijoules to kilojoules. A cell phone does not qualify - not even acute and chronic is several orders of magnitude below that. Every thing about the design conspires against it. 73's Richard Clark, KB7QHC |

There are guidelines available for this from the FCC -- it's a function of exposure time, frequency, and of course power. The numbers have been around for many decades now, and you might recall some questions about it showing up on your license exam. That being said, I'm not suggesting more studies aren't in order, just that many people have a very mistaken impression that there aren't already many, many studies that have tried to ascertain "safe" exposure levels to RF. (Another thing most people aren't aware of is that cell phone antennas are usually specifically designed to *not* radiate "into" the head. Ham radio antennas usually aren't, yet you see plenty of folking holding up a 5W HT to their mouths...) Some differences are that HT conversations tend to be a lot shorter. I'll bet my XYL spends 4 hours a day on various wireless and cell phones. I know some who spend more. But they are convenient, they are handy. You can walk around with them and do other things whil you are doing it. Its a "big help" in her business. That's okay, she thinks I'm nuts with my concern for cellphone use also. Hopefully I'm wrong..... Decades of living with "safe radiation levels" established for atomic elements sources which were "re-evaluated" to downward levels many times has made me a bit more cautious than yourself ... We've revised them downward because we've found out more about them. Life today is far, far safer overall than it was decades ago. Right. Its a learning process. We've found out about a lot of things that can do us damage. - 73 d e Mike N3LI - |

There's enough data to do this, only intelligence remains to perform. that's pretty simple.. Assume that the tissue has the specific heat of water. 1 Joule will raise the temperature of 1 gram of water about 1/4 degree C.. So, dump 2.55W/kg and you get about 0.0006 degree rise per second. Hang on the phone for, say, 10 minutes (600 seconds) and you'll get a temperature rise of a bit less than 1/2 degree C. For comparison: putting your head in sunlight results in an incident flux of about 1kW/square meter (peak). Assuming skin reflectivity of 0.36, the flux being absorbed is about 640W/square meter. Let's assume that the energy is absorbed in the first centimeter of your skin/bone, and that your head is a circle about 10cm in radius (e.g. 314 square centimeters).. That works out to about 20 watts total power being absorbed (compare to the 0.25W RF in the example above). Again, let's say that the density is 1g/cc, so the 20W is being dumped into 0.314 kg, or a SAR of 64 W/kg. That's a rise of 0.015 degree/second, or 10 degrees in 10 minutes. In reality, you won't see that much rise, because bloodflow carries some of the heat away, and so does convection. That was my point restated ever so diligently. After reading 1/4 of the "Biological studies..." it is interesting. 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 have seen data from a few of the experiments before and further experimentation would be a good thing particularly the ones that seem to describe low levels with certain modulation specifics. Also we need to differentiate the studies that involved 60 Hz AC fields which do seem to have an effect, but again more experimentation is required to try to figure out why some of these experiments conflict. I have performed an RF evaluation at my station and recommend prudence when operating. I am expected to do this because I am in control of the equipment and can make changes that may result in higher levels of exposure. Those who go out and buy the wireless device are limited by the FCC approval of the whole unit, and battery vs. talk time also limit the potential of exposure and hazard to negligible. Now as for certain people who equate that with hazards that require the defeating of safety interlocks to prove their point? Cars are dangerous, but most of all, people who run off the road into overpasses to prove the point. God help them. Real hazards are people trying to expose themselves to exhaust fumes with the vehicle in reverse or in a closed garage or removing the guards from lawn mowers and putting their hand in the blade or electing someone to public office that makes selections on judges, who also pals around with extremists and radicals, including those who hate the country they live in and make death threats on those they hate. You can judge a book by its cover if it is trying to tell you what is inside. Dropping some friends just because you are running for public office says something too. Also it seems to me that those who promote "change" without positive solutions are really seeking to destroy. |

Let's approach this from first principles. The battery in the phone is the only source of power. My own as an example has by the manufacturers rating - From Nokia for their 6263 model: BL-5C 1020 mAh Capacity; Talk time GSM up to 3 hours 20 min; Stand-by GSM up to 11.25 days Dump that capacity at a potential of 3.6V for the full talk time after a fresh charge gives us 1.10 W PER HOUR.

One of the problems I see is that frankly, there is a tactic being used here that is strangely reverse related to the old creationist argument of if A is wrong, or cannot be proven, then B must be the answer. It isn't. The warming feeling I noted is almst certainly NOT an actual thermal effect. I've touched my ear when this has happened, and it isn't a bit warmer to the touch - it only feels warm in my "headspace".Sorry, couldn't think of any other words to describe it. I'm possibly nuts (not all that likely) psychosomatic (maybe, but I doubt it) or maybe there is something happening here. - 73 de Mike N3LI - |

Now THAT is an argument for the books and sure to defy any measure, qualification, or solution. We may as well speculate that if you fall out of bed while dreaming of plunging off a cliff, then you die when you strike the floor. This is called an anecdotal report - and the Bible is full of them. Unfortunately, theologians don't really argue the Bible, they argue religion which has some very rigorous protocols. I don't see any protocols observed in the anecdote and is one reason why the Vatican rarely admits new miracles. If it worried you as a real problem, you would probably stop it. This is a common protocol that needs no authorization from the Pope. If you don't stop, then perhaps you might want to re-evaluate the diagnosis of being nuts (avoiding a real problem is NOT psychosomatic). If it doesn't worry you as a real problem, this is simply navel gazing and still does not rise to psychosomatic. That's OK too, because hard science has already finished off the substance of the issue. If you want the science behind the "perception." I would offer that it is only remotely associated with Physics as initiator, and backfilled with the Ape's reflex of drawing away from the fire (the scienz of psychology that you anticipate above). Thus it devolves to the allowance that, yes, perhaps you might catch fire if you used your cell phone in your sleep. That should spawn traffic in yet another side thread that arcs away from antennas. 73's Richard Clark, KB7QHC |

Unless someone comes up with other figures (you will need the creationist un-approved full four function calculator), it would seem that nothing less than navel gazing can propel this thread further. I applied similar calculations to a jalepeno pepper I ate today. I took it out of the refrigerator in which it had stabilized at around 35 degrees. Popped it in my mouth and munched away. The pepper made my mouth hot and it burned pretty good. It isn't possible to do that. Given that the pepper was at 35 degrees, it in fact should have lowered the temperature in my mouth temporarily until blood flow could compensate. Further inspection showed that there were no apparent blisters or unusual redness in my mouth after eating the pepper, so the only conclusion I can make is that the sensation I felt, I did not feel. - 73 de Mike N3LI - |

Hi Mike, Not likely? This "certitude" falls into the same category of speculation that began this side thread. The rhetoric of "not likely" automatically admits it into having the same small possibility of cell phone tumor risk. Admittedly, this is the first time that I have heard "not likely" turned into certitude. I would at one time have said that wasn't very likely. One might begin to think that there is bit of a difference between scientific discourse and English discourse. That is likely. Whereas I highly doubt that it would happen, you use that doubt as a springboard to add to the issue. All without answering my question! I doubt that using a cell phone wil cause me to crave lutefisk either. So we add another possibility to the mix. Ask a scientist if a singularity might show up and start spitting to coffee cups S/he will probably say "not likely", when indeed it is almost impossible, yet not eliminated. Something like almost infinitely unlikely, depending on if we ascribe to the big crunch eventually following the big bang, or even the big cigarette. But at least take a shower. But I digress..... It doesn't ipso fatso mean they accept that as a real possibility. But the odds, as scientists look at them, make it difficult to state 100 percent yes or no.

We are now engaged in debating what is "not likely," but of course that is how it started out anyway. What is embraced as a real risk is equally dismissed by the same logic. Anyone who worries about CNS tumors induced by cell phones, must allow that they could suffer spontaneous combustion from the same source, same risk. Risk, after all, is not a thing, it is a number. Without data, employing risk as rhetoric automatically elevates everything that was once inconsequential to life threatening.

The same could be said of Phosphorous going in the reverse direction. Exactly! Not. The power or lack of it on the part of cell phones to cause much direct thermal heating does not mean that one who experiences the sensation of heat is not feeling it. The Jalepeno has a chemical which triggers pain receptors on your tongue, mucus membranes and skin. Your sodium example - and puhleeze don't anyone try that,it is an extremely vigorous reaction - is based on sodium's reactivity with Water. Just as the odd heat sensation that some people get from extended use of a cell phone, there is probably something else going on. Direct thermal heating via cellphone is at best a red herring. Heating sources abound, so I just don't buy it. You willing to witness this test (sodium or phosphorous) to confirm the supposition? I'll pass. I wouldn't mind watching from a distance though. I'm foolish that way. Remember, I'm the one who uses a chainsaw to dig his radial trenches. (Don't try this at home kids!) Better yet, can you prove that the jalapenos don't lead to CNS tumors. Are you willing to accept the responsibility for your stand that they don't. Side note - they've recently found out why hot food is popular. Over the years, people have suggested reasons such as making people in tropical zones sweat to cool them off, or a sort of masochism. I never bought either of those, although I can get a good hot food sweat going, but it just didn't make sense to me. Turns out that after the initial burn, the same chemicals give you a bit of euphoria. Receptors in the brain apparently enjoy it. Looks like a new target for the war on drugs! ;^) "Your honor, the task force did observe the defendant consuming several objects that after testing in the lab and from stool samples, turned out to be capsicum annuuum" We arrested him on the spot, Tasers were used, as pepper spray would only enhance his high, and would possibly lead to a Hot High, during which offenders are known to experience superhuman enjoyment." - 73 de Mike N3LI - |

It is the energetic/fast/absolute reversal of the dipole water molecules (and even oxygen molecules) which would seem the most obvious area of exploration ... indeed, I have seen reference made to the "spinning" of this molecules. This: "Dipolar Bonding in Water The dipolar interaction between water molecules represents a large amount of internal energy and is a factor in water's large specific heat. The dipole moment of water provides a "handle" for interaction with microwave electric fields in a microwave oven. Microwaves can add energy to the water molecules, whereas molecules with no dipole moment would be unaffected. The polar nature of water molecules allows them to bond to each other in groups and is associated with the high surface tension of water. The polar nature of the water molecule has many implications. It causes water vapor at sufficient vapor pressure to depart from the ideal gas law because of dipole-dipole attractions. This can lead to condensation and phenomena like cloud formation, fog, the dewpoint, etc. It also has a great deal to do with the function of water as the solvent of life in biological systems. " From he http://hyperphysics.phy-astr.gsu.edu...ic/diph2o.html Makes note of the fact microwave DO cause noticeable effects/affects in just water ... there are other polar molecules in the body which have NEVER been the subject of study in relation to microwaves ... this is simply a fact ... Those who would claim all is known, nothing of significance will ever be discovered of microwaves, even low levels, effect on the body, are simply idiots--isn't that obvious and totally apparent? If these idiots can convince others they have some form of "psychic knowledge" which requires no more scientific testing/exploration--well, the term, "Buyer beware" comes to mind ... Why would anyone argue against "confirmation of safety", unless one has a horse in the race or is just an idiot with "a message from God?" Regards, JS |

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 |

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.

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. |
