Fun and games with a CB radio....

Here's a party trick anyone can do with a car CB radio and a Weiner.

Spear the Weiner onto the end of the car antenna whip (obviously it'll need to be a stainless steel antenna and not a fibreglass helical antenna).

With the Weiner on the end of the antenna, key up the mike for a minute or two. The Weiner will be cooked or hot.

And here's another magc trick with radio....

Hold a unconnected flourence tube, straight out of the box, next to the CB antenna and have someone key up the rig.... Whoa, the tube lights up without any electrical power!! Freaky man!!

Polarised radiation can also excite the Neon gas inside the tube and cause it to glow.

Now run your hand along the glas tube and you'll find that the tube will only be lit up to where your hand is!!

When , say a woman, is having a yack attack on her mobile phone, this polarised field is projected through her skull. Notice how your mobile makes your ear feel warm after a few minutes??

I wonder, how much of that heat is due to the polarising radiation, and how much of it is due to an energized electronic device being placed close to your body and thus receiving your body heat and that heat being insulated by both the device and your ear.

Oh, and another thing about RF not being able to heat up human tissue....

I didn't say that RF couldn't heat up human tissue. I said at the power levels involved it couldn't heat tissue to any appreciable degree. Additionally, tissue heating doesn't damage DNA and can't cause cancer.

I have been caught (enveloped) in a high powered polarised filed whilst up a VHF radio mast on a very hot summer's day.

I was tuning and adjusting the impedence matching stub on the antenna and climbing down the 20 foot mast, standing clear and yelling, "clear" into the walkie talkie back to the transmitting station. They, in turn, would run a Standing Wave Test, lasting about 20 secinds and then tell me it was safe to climb back up the mast to fettle the adjustments.

After 20 odd trips up and down the ladder, I decided that I would be safe if I hung on under the mast in what I believed to be a lobe null point under the antenna. No I wasn't, it turned out, as when they fired up I had the sensation of millions of ants running under my skin for 20 second.

OK a polarised field will stimulate a current in any piece of metal, no matter how small. This includes Iron particles in the blood and with several hundred Watts of power to back it up, this particlular polarised field managed to generate enough current in my own blood to trip out nerve endings.

When a mobile phone makes your ear or face feel warm, it is the action of the phone's antenna's polarised field working on the Iron in your blood. If your anemic, you might not experence this to much effect.

The higher the frequency, the more effet it has on blood Iron and other trace metals in the body.

Strangely enough, it was this principle that they were intending to use for radio death rays to kill enemy bomber crews inthe 1930's. It proved to be unworkable, but, as a spin off, they managed to invent RADAR instead.

There was a thing in the US, back in the 1980's, where FBI agents were suffering Ear and Face cancer about 5 years after the FBI replaced it VHF walie talkies with new Motoarola UHF sets running in the 500 to 600 Mhz. band area.

The investigation revealed that these 15 Watt tranceivers were causing the problem and now FCC rules ban any public and government UHF hand held tranceivers exceeding a power output of 3 Watts. The UK and EU also have similar rules on unlicenced public and government hand held tranceiver equipment. They had a feature in a radio magazine and it worked out that an FBI agent needed hust to use a WT for just under 20 minutes to take in 400 Rads of exposure. So in an average day's use, an FBI aganet could take in several thousand Rads of exposure to polarised radiation to the Face and Ear.

However, qualified and licenced people are allowed to used any level of power up to 150 Watts in a UHF hand held unit, though they'd have to be stupid as they'd clearly know exactly the amount of damage it would do to them. (That's in the UK and EU.... The US has even higher power limits!!)

This was all about 23 years ago. There should be something somewhere on the web about it even today.

The international warning symbol for polarised radiation risk is a radio mast with ball topped anteena, with lightening zig zags coming from it, on a yellow triangle, worded, "Warning!! Polarised Radiation Hazard!!"

Usually found in hospitals around the MRI scanner area and RADAR instalations.


Polarising Radiation is measured in Microvolts per square Metre over a quoted distance. This is because the measuring equipment is a OA81 or OA91 "Cat's Whisker" Germainium diode across a Micriampmeter with the + terminal attached to the corner of a 1 Metre square copper plate. The plate is held braod side on to the test source and the measurement is taken.

Yes, you could easily make the equipment yourself at home for peanuts.

All transmitter equipment sold in the world has to state this figure and your mobile phones will have it quoted in the specifications.

Mine quotes 3 Microvolts per square Metre @ 10 Metres, in the specs, which is low for a transmitter.

A 4 Watt CB rig clocks up more than 40 Microvolts per square metre @ 10 metres. I've actually measured one a few years ago!!

Now here's a thought....

They only want to cure you of cancer so that the care homes can rip you off when you become too old!! If you de of cancer before growing old, how are the care homes going to deprive your kids  and grandkids of your estate??!!

When a mobile phone makes your ear or face feel warm, it is the action of the phone's antenna's polarised field working on the Iron in your blood. If your anemic, you might not experence this to much effect.

I'm curious, have they actually done tests on cell phones to confirm this?

My sanyo katana phone gets fairly warm after I've been talking on it for 30 minutes or so, with the ear piece being the warmest. But get this, the antenna isn't near the ear piece, its on the bottom of the phone.

Generally only the phones earpiece area tends to warm because, I'm guessing, that the device is using more power, and it's close proximity to my body is trapping body heat.

Not trying to be contrary here, I am aware of RF energy heating tissue at high power levels (Satelite transmitters, radar, etc...which is why before we do any tests at work on the Satelite gear we always have to have it turned off) but I wonder what the genuine cause of tissue heating in the case of cell phone usage (IE your ear) is. How much of it is the RF energy, and how much of it is trapped body heat, and energized electronics I wonder.

Speakers do generate heat.

A friend used to have oil cooled speakers to run with his 1 Kilowatt music system (he obviously didn't hit it off with his nearest neighbours half a mile down the road, but hey, it was like being at the heavy metal concert in the fornt row!!

Anyway, he had to periodically change the collant oil and leave the caps off for a few hours to let the air bubbles escape.

So one mornig, before work, he puts in new oil and goes to work. In the evening I receive a phone call for help. Yep, he'd parked up his motorcycle, come in stuck on a Crass (Punk  Rock Band) LP and whavked up the volume. Oil was everywhere in the room!! I just creased up when I arrived and saw the mess!!

The point is that the little speakers could generate heat. Also the internal workings generate heat and the speaker slit is a good vent point. Your ear just happens to be next to it. The thing is that RF will stimulate sensations in the skin through Iron and other metals in the blood and tissue. The phone would be physically warm to touch when tested by touching against other areas of the body, if the speaker is generating the heat. RF heating takes time to be noticed. My phone has the antenna next to the speaker, as do most phones and I've noticed this heating effect and it isn't the speaker as the phone is cold when pressed against the skin elsewhere on the face.

They do have to test phones but as far as what is the safe RF power benchmark and what isn't, isbased on years of scientific speculation. They aren't that sure that this is right, even now.
