I am sure you will grant me that "writers' license." grin Regards, JS That's the trouble with you people. You insinuate by "asking a question" or making up a meaningless phrase like "noticeable damage" or "common sense laws" in such a way that it panics the ignorant or non thinking people into running over a cliff or voting, then you sit back and feign ignorance. Just beware you don't get caught in your own stampede. I submit that power tools should be rendered safe before exposing them to people with "artistic license" or who feel themselves "not responsible" for their actions because they are crazy. We know that the human body can be harmed by just sitting in the sun too long. How much RF at what frequency has or has not caused damage to those who have been or are exposed, has been addressed only by FCC setting an arbitrary specification without supporting data other than that supplied by military microwave studies with respect to high powered radar. Nor do the studies support that there is noticable damage by observing the military safety standard or by the FCC standard that sets limits much lower, and even lower still for those who aren't knowlegable on the subject.. So then it is anything but an objective issue. I too have been exposed, but limited my exposure based on time averaging, so I have encountered field-densities thousands of times greater than a cell phone for a several minutes and hundreds of times, for as much as an hour with no discernible effect in the long or short term, but have encountered unknown intense fields with short term issues, such as headache in the evening after exposure, but gone in the morning. I have certainly encountered the same thing more often from over exposure to "a day at the beach". Case in point: As a nonsmoker, I have problems reworking PC boards because my employer has no plausible deniability that any respiratory ailment I might succumb to in later years wouldn't arguably be caused by a self-inflicted lifestyle condition rather than an employment hazard. In the face of other more serious health risks such as sunstroke, falling off a tower or electrocution, RF exposure is a common sense issue for hams and those in the business, and a non-issue for those who will never enter restricted areas. In fact, there are far more daily hazardous things that we encounter, as to obliterate any test data. Your Petri dish and sal****er experiments have less credibility than the anecdotal. It's like the illegal alien issue. Due to the lack of proper judgment and widespread hysteria, more housekeepers and migrant workers will suffer than gangbangers who find prison to be a climate-controlled mailing address with a few inconveniences, but "three hots and a cot". Deportation gives opportunity for those with plenty of drug money to do it again. All the hysteria does is help to polarize nationalism (and foreign nationalism). With the population of foreign nationalist gringo haters in this country outnumbering those in Mexico, why do we need fences at all? Perhaps for a start, we might plant more businesses in Mexico rather than having everything shipped all the way from China. |

So far, NOBODY has shown that to be the case. Not even in the 2.4 Ghz ISM Band where BlueTooth operates, with significantly LESS Power Density.

Milliwatt Cellphone, operating one one of 4 Bands in the 800-900 Mhz, and 1800 - 2000 Mhz, will cause ANY Measurable Heating in Human Tissue, and therefore cause some sort of problem. So far, NOBODY has shown that to be the case. Not even in the 2.4 Ghz ISM Band where BlueTooth operates, with significantly LESS Power Density. There are enough of these devices around that should all this "Wild Speculation", actually have Observable Effects, the researchers into this area wouldn't be needing to do Statistical Analysis, to Magically try and prove some nebulous Causal Effect. ==================================== It might be useful to know that the RF power radiated by any cellphone is dependent on the distance between the device and the nearest base station. In a built-up area or along the highway with nearby base stations the power can be very low ,whereas at remote locations it can be as high as 2 Watts (at least here in Europe). Living away countryside ,when using my cellphone at home the battery drains rather quickly compared when using the device in town. When holding the cellphone near my HF transceiver I clearly hear the digi-noise. For this reason I avoid using the cellphone while at home or at other locations away from a base station. My home is approx 8 km (5miles) from the nearest base station. Frank GM0CSZ / KN6WH in northern Scotland UK |

Yes, I have heard that argument before, with tobacco ... Nicola Tesla once said chewing gum was more damaging than alcohol ... This URL: http://en.wikipedia.org/wiki/Thalidomide This drug was once thought "safe" and marketed/sold in over 50 countries. It was thought so safe, it was given to pregnant women, causing innumerable birth defects in children (children born without hands/arms/feet/legs/etc. Your argument against caution is simply ignorance such we have seen in the past ... some of us learned. Even when the BEST AUTHORITIES say is is "OK", use caution! We know that the human body can be harmed by just sitting in the sun too long. How much RF at what frequency has or has not caused damage to those who have been or are exposed, has been addressed only by FCC setting an arbitrary specification without supporting data other than that supplied by military microwave studies with respect to high powered radar.

I have certainly encountered the same thing more often from over exposure to "a day at the beach". OK, so do an experiment yourself to test the amount of damage! 1) Cut an opening in the door of your microwave. 2) Insert your hand. 3) Turn on the microwave for 5 seconds. 4) Repeat 1 - 3 until "noticeable damage" occurs. 5) Come up with a time you think it is "OK" to microwave your hand; quite possibly, you may wish to consider a time MUCH LOWER (as a "test standard", note that zero seconds will ALWAYS be safer) than the time to do "noticeable damage." (Disclaimer, the above is only meant as a warning to demonstrate the ignorance of the previous posters logic -- i.e., IT SHOULD NEVER BE ATTEMPTED FOR ANY LENGTH OF TIME!) Or, don't do this yourself, EVER! Case in point: As a nonsmoker, I have problems reworking PC boards because my employer has no plausible deniability that any respiratory ailment I might succumb to in later years wouldn't arguably be caused by a self-inflicted lifestyle condition rather than an employment hazard. ABSOLUTELY! OTHER things cause cancer/illness, a search of the internet will provide you with countless and proven substances/tasks/jobs/etc. which you should provide. If you think there is a real danger with ANY job you take--QUIT--IMMEDIATELY! But then, you can't protect some from themselves, those will die for their occupation/job. :-( In the face of other more serious health risks such as sunstroke, falling off a tower or electrocution, RF exposure is a common sense issue for hams and those in the business, and a non-issue for those who will never enter restricted areas. In fact, there are far more daily hazardous things that we encounter, as to obliterate any test data. Your Petri dish and sal****er experiments have less credibility than the anecdotal. Hey, some will make a trade off and face such serious consequences to their health and safety in exchange for money -- I only hope their compensation is justified, at least to them. Again, some people cannot be saved from themselves ... and then, once they have made such a BAD decision, they only wish to blame others. If you are too stupid to protect yourself, am I required to do so? (I mean I will, but then, I will not let you work at places injurious to you! I mean, for God sakes man, you will raise insurance premiums through the roof!) It's like the illegal alien issue. Due to the lack of proper judgment and widespread hysteria, more housekeepers and migrant workers will suffer than gangbangers who find prison to be a climate-controlled mailing address with a few inconveniences, but "three hots and a cot". Deportation gives opportunity for those with plenty of drug money to do it again. All the hysteria does is help to polarize nationalism (and foreign nationalism). Well, I guess, declines in the American living standards, importation of 3rd world conditions here, lack of medical care for millions, untold people without home ownership, etc., is nice! -- if you like that sort of thing ... personally, I would seek other/more-positive solutions. With the population of foreign nationalist gringo haters in this country outnumbering those in Mexico, why do we need fences at all? Perhaps for a start, we might plant more businesses in Mexico rather than having everything shipped all the way from China. Well, we could just give them everything, then hate them for having it and work for slave wages getting it back and just keeping fed, I guess; again, some people have different ideas. Personally brother, I would move away from such conditions -- but that is just me ... Regards, JS |

Sorry, I missed the point where that ever came into question ... however, yes, chuck a neon tube in a microwave, the gases WILL ionize, but then the bulb will probably explode, LOL! Regards, JS |

My Motorola Razar V3 phone is approx. 6mm thick (when opened), and where the antenna is buried in the phone. This means the antenna can be no more than 6mm from my head if the phone lies against my head. Now, we assume the phone is emitting 300mw. This would be equivalent to 1.2w of power emanating from that same antenna at a distance of 12mm from my head. And, the latter would be equivalent to 4.8w emanating from the same antenna at a distance of 24mm from my head. And, the last would be equivalent to 19.2w emanating from the same antenna at a distance of 48mm from my head ... your higher figure, of two watts, is simply frightening ... The lunacy is exposed ... correct any error you see in the above ... Regards, JS |
