Cell Phone dangers

It's my first post and I would like to start off with one that has been on my mind lately.

www.electropollution.org...

According to this research the following occurs:

1. Cell phones put out an electromagnetic field (EMFs).
2. Your body's cells that have extended exposure to electromagnetic fields can turn cancerous (think high tension power lines and their relationship with leukemia), especially in children due to their extended, cumulative exposure to EMFs.
3. EMFs from electrical devices such as cell phones are a form of low level radiation that has an effect on the cells of your body.
4. Even though brain cancer and tumors of the ear have yet to be definitively associated with the EMFs from cell phones, you must remember that there is a bone (aka your skull) that protects your brain from direct EMF involvement from your cell phone. Your breast tissue, however does not have this same protection (yes, both men AND women have breast tissue and yes, men can get breast cancer).
5. Your cells phones put out EMFs regardless of whether or not you are speaking on the cell phone. Unless you are on airplane mode, which then precludes the need to carry your cell phone around in your breast pocket.
6. Cell phones carried in the front pocket of your pants have been related to lowered sperm quality in men. Also, sperm quality was found to go down the more time a man spent on a cell phone as well.
7. There is an increase in oxidative stress, increased free radicals and a decrease in anti-oxidants in tissues near the exposure to a cell phone.


Now those may be the physical...but what about those cell phone towers?

I would be more concerned about the much higher level of EMF from overhead powerlines than the .3 watt signal EMF from a cell phone.

There isnt any solid evidence linking cell phone use to many of those things listed that are being addressed.

Prolonged exposure to EMF can cause much of those problems, but it also depends on the level of the EMF and is porportial to the strength of the EMF in question plus frequency. At .3 watts on the frequencies of cell phones which varies all the time, one would have to be holding a cell phone, fully active and transmitting for several days consistantly before any trace of the effects would be measured.

Unless someone was connected to their charger and put on hold for that time frame, which I seriously doubt ever happens for that long, using a cell phone even for the duration of a typical cell phone battery charge wont cause these problems.

Its more scare tactic than anything, equivilant to all the other silly things that are bad for you.



Cheers!!!!

Why did cell phone manufacturers unilaterally decide to decrease the wattage output of cell phones? If they are so harmless, why cant I get a phone with better output? My reception where I live is marginal at best. The 1st phone I had back in the 90's had higher output and better reception.

A mixture of placating fear as a PR exercise and it probably had design implications as well, such as battery life. Technical advances also make it possible to do the same thing with less power.

So none of you are the least bit concerned that it might be destroying the immune system? That's all I'm trying to get at.

Just another nail in the Human evolutionary coffin.

"might" being the operative word.

My immune system is fine, thankyou very much.

If you care so much about cell phones, why not radio's? Or TV's? Or the signals used to broadcast? Or microwaves? Or computers? Or cars? Electricity in your home?

All emit EM fields, some are alot stronger than cell phones.

The cell phone takes advantage of the cell tower, where the transmitter is at much higher power levels, and the receivers are extremely sensitive, thus makes up for the low power level of the cell phone itself and is why the power levels are able to be reduced, plus uses less energy from the battery.

The EPA and FCC did studies many years ago on minimum antenna hights per given power level and frequency that would have the least impact on the environment. The minimum hight is 200 feet. If the cell antenna structure is on a shorter tower, the power levels from the transmitter are set accordingly so that they do not exceed the calculated maximum permitted power level for that hight.

There is more EMF damage from power lines, especially those cross country high tension power lines that carry 400+ Kv on each wire, cept the ground wires located at the very top. Since those are under constant load, and as any wire carring electrical current that is loaded produces an EMF, those lines are always more of a threat than the EMF from the cell phone.



Cheers!!!!

Not really. Why? Well as I pointed out, you would have to be on the cell phone for a very long time before it even began to show a tiny amount of any influence on the body. I can expect more immune system damage from a flu shot than from a cell phone.



Cheers!!!!

Since there is no fear of damage of using them, let's think outside the box at why they are used besides talking to your best friend about mindless bs just because you can.
I mean it's a strange thing to think about how every person almost 10 years ago did not have a cell phone. Alright I understand there may not be enough evidence to show damage, but what about walking through a crowded hallway and everyone is transmitting and speaking, your saying you cannot feel something in the air? Almost like saying you can pull out your phone at the very same moment someone calls you.
You say that this is normal? This was created into our society, now what is it doing to our genetic makeup?

The question is valid. One worth examining in detail. Lets do just that.

In the scenario you pointed out, in a crowded room or other, lets assume you got 100 people all using a cell phone at the same time.

The first thing that would happen is every user in that room would experience co-channel interference from so many cell phones in use at the same time in such close proximity. With 100 of them being in use that close to each other, they would all be using the same cell tower and cluster of frequencies, thus some would either get consistant drop outs because the cell tower system is trying to allocate frequencies and bandwidth to 100 cell phones, and the close proximity of each cell would also cause co-channel interference. About 40 percent of the 100 users would simply get errors or no connections due to the fact that each cell tower interconnect system has about 20 maximum channel capacity. That is why you see multiple cell antennas on a cell tower site, pointing in different directions, each adding to the cell tower capacity capability.

Ok so lets cut that usage in half, to 50.

50 cell phones going at the same time in a room crowded with 100 people. The effect would be very minimal. The cell phones are not "combining" their signals to produce a large signal, each are on a different frequency and only putting out a maximum power level of .3 watts. Depending on how far away they are from the cell tower site, that .3 watts may even be less. The cell phone power output level adjusts accordingly in relation to the distance from the cell tower it is connected to. So chances are that if your in a congetsted area, like a subway or at a crowded mall or something like that, there is 1 in 1000 chance that your cell phone is putting out its full .3 watts because cell phone towers are abundant and cell sites dont always use a tower, they can be mounted on top of tall buildings and even some cell facilites are located in and around congested city blocks and mounted on short towers or the sides of buildings and traffic light structures.

The reason is to eliminate the drop outs and provide the "full bar" service. So again, that would make the cell phone transmit less power than the full .3 watts.

This all doesnt mean that it is not possible that a cluster of phones going at the same time "might" be of concern, but realistically, the chances of it being a concern is very minimal.

Cell phones use the skin effect.
They go around you, not through you.
You could stand at the top of a powerful transmission tower and your internal organs would be fine, but your skin would be melted off.

According to my EMF detector my cell phone gives off less than 1.

My alarm clock on the other hand gives out ton's basically it maxes out my EMF detector. Mine stops measuring at 25 so it pegs out there with the alarm clock.

So somewhere down the road in our time, we won't see some sort of baby being born with a wi-fi sensing type of cell within its genetic makeup? I'm leaning more towards some sort of disgusting evolutionary adaptation to the e.m.f's and e.l.f's ect.

That depends on the frequency. If its in the UHF from about 300Mhz on up, you will "cook" from the inside out just like how a microwave cooks.

Lower frequencies, yes your cooked from the outside in.

Best thing to do is not stand next to a transmitting dish or antenna! Tho it looks like fun to climb those radio towers, there is death at the top. Especially if its a full power UHF television transmitter. Those things usually run in the gigawatt range. (ERP-Effective Radiated Power)


Analog tv transmitter specs
VHF low-Ch2-Ch6 maximum ERP 100,000 watts. (digital tv n/a)
VHF hi-Ch7-13 maximum ERP 360,000 watts. (digital tv-half of analog ERP)

UHF Ch14-69 (varies with location/terrain) typical 1.5 to 4.0 Gigawatts. (digital tv-half of analog ERP)

Radio broadcast transmitter specs.

AM clear channel maximums in the US-50,000 watts.
AM daytime regulated operation in the US-5,000 watts typical
AM nighttime reduced power in the US-250 watts to 500 watts typical

FM Class C 100,000 watts ERP
FM Class B 5,000 watts ERP
FM Class A (low power) 10 watts up to 500 max ERP



Cheers!!!!

It has been shown that prolonged exposure to high level EMF can cause birth defects. Not to the extent of babies having wi-fi abilities (lol) but definately some pretty nasty deform effects have been noted.


Cheers!!!!

I worked for a cell phone company for 5 yrs. I had the cell phone on my left ear most of the day. A good 5000 min per month. After awhile i would notice that my ear would hurt and also get very hot (of course). A collegue of mine was experiencing the same problem. It wasn't a headache, but a pain in the ear that is very hard to describe. Well, he went and had the doctor check it out, Doc said he was fine. Whatever. Well, I left the company and use my cell phone as little as possible now, BUT, when I do use it the pain instantly comes back. It doesn't happen as much when I switch ears, but my left ear is my phone ear, more comfortable, can't help it. So, does anyone else have this problem? Years ago they said it wouldn't cause damage, but cell phones weren't around long enough for them to test the long term side effects, lets say 20 years of constant cell phone use. How can we live without cell phones anymore?? Internet?? Etc.. Lets just wait and see what happens in another 10 years. I hope I'm wrong, but I don't see good things happening.

They mention that it is nearly close to the same frequency as a microwave if not more.

And those satellite dishes and radio towers just make anyone paranoid, I even heard of some strange stories that may or may not be true that took place in the 40's when the radar was really beginning to take off, and some guy on a ship decided to walk in front of one during a full blast transmission. So the big question must be...is it getting safer or more harmful? Being around too much Wi-fi makes me fatigued, does this affect anyone else by chance?

Update:

Found some more information on SAR's

www.fcc.gov...

Please read about it.

And here is a link for the 20 top cell phones that give out the worst levels of it:

I almost never use my cell phone without using a wired headset. I have one in the car and one in the house. If I do make a call using just the handset, it is never for more than a couple of minutes.

This method not only reduces EMF risks, but also makes talking much more comfortable. Using wired headsets instead of Bluetooth is also more convenient for me, as they don't need batteries or recharging.

Mostly, I just don't talk on the phone very much, especially in public. I have that luxury.
