Remember, intentional use of radio began over a hundred years ago... Radio has existed since the beginning of the universe. A 30mW radio pulsing out bits every now and then simply has no impact on health.
I think the headache syndrome and "RF hypersensitivity" is completely psychological. People tend to blame problems on things they cant see or understand. I've seen: "oh, that's a radio?? Man, I have a headache." or maybe "Oh, that's what was causing my headache". Maybe they should drink more water ;) Non-ionizing radiation can be dangerous, but not in the way you would suspect. Very strong RF fields can create heat when they transverse matter. If the RF field is intense enough (and it does take quite a bit of energy), it can cause burns -- internally and externally. A microwave is a good example of this. Exactly why a 700 watt microwave takes 3 minutes to bring water to 175 degrees, and a 1500 watt microwave only needs a minute. Its not just 2.4GHz that does this, RF of any frequency can cause similar heating effects. Heating affects are also cumulative. Your 100mW card, 600mW cell phone, and 5 watt VHF radio simply cannot generate enough heat to make any difference in tissue temperature. Sitting in front of a fire, in the sun, or the temperature of the air will have more affect on tissue temperature. The electronic in your cell phone that create heat will warm your head up orders of magnitudes more than the RF limping along out of the antenna. If you are concerned about close proximity to high powered RF devices, its not a guess, it's a very well understood science. Visit an RF calculator to determine what safe distances are. -----Original Message----- From: Julián Llantén Trujillo [mailto:[EMAIL PROTECTED] Sent: Thursday, October 09, 2003 11:22 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: [BAWUG] Re: [SOCALWUG] Parents sue school over WLAN's health effects on children mind.
