The dangers of RF power

[MACK E-6]

I have a question. I noticed on the fence at the base of a cell phone tower a sign that said something to the effect of "Danger-RF power may exceed the limits for human exposure."

What is the limit for human exposure to RF power? These guys with linear amps may want to know.

Well - looking at the way the Cell Phone industry works here, on one side of a railway track you have a signal and the other you don't, it would depend on if the signal is directional or omni-directional.
A recent study said males using a cell phone for extended periods have a lower sperm count:

Hours of chatting on a mobile phone are suspected to be slashing male fertility around the world, new research shows.
Men who use mobile phones for more than four hours a day produce fewer and poorer quality sperm, according to results of a study released at an American Society for Reproductive Medicine conference in New Orleans.
London's Daily Mail reported that doctors think sperm counts and quality might be damaged by electromagnetic radiation emitted by handsets or the heat they generate.
The Independent said the study suggested that microwaves from mobiles appear to reduce the number, mobility and quality of sperm by almost half, to the point at which some men might become infertile.
Sperm from heavy mobile users had a 30 per cent drop in the capacity for movement and viability when compared with sperm from men who did not use a mobile phone, The Guardian reported.
The findings come at a time when many nations are asking why the fertility rates in their male populations are falling.
Almost 1 billion people around the world use mobiles and in some countries the number is growing at 20 to 30 per cent a year, The Independent said.
The Guardian said the study was too preliminary to prove an unequivocal link between mobile phones and falling sperm counts.
However, it said scientists want to look at mobile usage taking into account other factors such as age, weight, smoking, stress and whether people have sedentary jobs.
Ashok Agarwal, who presented his findings at the conference, said they did not prove mobile phones were damaging male fertility, but he called for more research.
"People use mobile phones without thinking twice what the consequences might be," he said.
"It is just like using a toothbrush, but mobiles could be having a devastating effect on fertility."

These drivers running these amps just don't know how bad RF is for them. Exposure to it is like X-ray's and MRI....same thing only in smaller dosages.
Unless of course you have I would say above 1000 watts. The reason I say this is because a 1000 watt amp is as big as I ever had. So anything bigger I'm guessing is alot worse.
I was going to add to my other post last night, but I was too tired about RF absorption, I found some really interesting information about it I will post here later this evening.
Only thing I will say right now is.....it is not worth it to have a amp.

The FCC places limits on how much rf radiation can be transmitted within a certian radius of places where people may be exposed (called MEP). These limits are based on the amount of time a transmitter is transmitting at a specific power level on a specific frequency. These limits protect the public by keeping rf radiation exposure to a minimum. The fence and warning signs are there to keep people from getting on the tower while its active and being exposed. Current cell phone frequencies are very close to microwave frequencies and can cuase severe damage to your eyes at certain power levels. A tower uses very high power levels so you should not get too close to it. As far as cellphones go, they use a very low wattage for transmitting and are not harmful to you over the standard amount of time it takes to make a phone call. If you talk on a cell phone or cordless phone for many hours regularly, there can be a possibilty for some effects due to exposure.

Answered very well!

If we all lived by what were told,we would still die of something besides old age. Do you ever get tired of people telling you don't do this or don't do that, cops speed,lawyers lie, drs screw up and no one tells. Coke will give you cancer, poisons in almost everything you eat, exercise can kill you,exercise can't kill you. some drs are fat,some eat junk some don't,some ski some still drink and smoke. You do everything by the rules and regs and nobody seems like they do. Listening to some of these posts make you think that the persons a perfect being, if he was he wouldn't claim to know everything. Its too much fun to have fun,I guess,If you regulate everything us truckers couldn't make a living like we should. Most of you guys know just what i'm saying and why. Had to speak up for the minority I guess. Until I retire,I will make every dime I can for me and my employer,come hell or high water.

Cryin' Towels here...Get your cryin' towels....

We are not trying to force you to do anything...........We are trying to inform you.........

The 3 items on the human body damaged most by RF are your eyes, your brain and your testicles...........

I guess you don't use any of these things..........

Your rant would be better served in a different post it has nothing to do with this post. Why do people create their own topics inside someone elses?

[buck and a half]

Probably because some of us are subjected to all of these waves,your microwave, radio towers you may live near, your cell phone you use everyday,sorry if it went over your head. They all have been said to be bad for your health,even your headphones.

Yes, but your post mentioned nothing about that it just ranted about regulation and stuff. It would have been more relevant had you mentioned just that and not a long rant about everything.
