Would People Stop Using Mobile Phones If More Evidence Shows Them To Be Carcinogenic?
from the just-wondering dept
Lots of folks have been talking about the recent WHO report which says there's now enough evidence to indicate that mobile phones are at least somewhat carcinogenic. Of course, for years there have been ongoing dueling studies on this topic, with plenty supporting this view, and plenty saying there was no such evidence. Frankly, I have no idea which side to believe, but am wondering: will this news actually cause anyone to stop using their mobile phones? I'm sure there will be a few people here or there who will go that far. For others, it may just result in them not keeping the phone so close to them all the time, or maybe even turning it off at times. But I'm curious to hear from anyone out there who actually plans to radically shift their behavior due to this report. Are you out there? Can you explain your thinking?

A bluetooth headset is something in the range of a milliwatt, because it only has a 30 foot range or thereabouts.

"It has been argued that cellphones are safe because a single microwave photon does
not have enough energy to break a chemical bond. We show that cellphone
technology operates in the classical wave limit, not the single photon limit. Based on
energy densities relative to thermal energy, we estimate thresholds at which effects
could be possible. These seem to correspond somewhat with many experimental
observations."

Re: Re: Re: Re: Re: Bluetooth signal strength
Actually, it showed that DNA does not readily absorb microwave radiation. The water in the cell does. Sudden burst heating of water in the cell can mess things up, but that requires very concentrated heat and much higher power levels than cell phones emit.
It is possible that mild internal heating of cells could cause issues.
There was also a recent study with microwaves on living tissue. At least on earth worms, mild dosages of microwave radiation was beneficial to healing and growth.
They're thinking of going to human trials soon to see how well microwave radiation helps heal us.
Yay, cell phones might be healthy.
Either way, we need more data.
Ohh and research in some European country that by law required cell phone usage in the death records, actually showed an identical cancer rate between cell phone and non-cell phone users, over 30 million people over 20 years.

Re: Re: Re: Re: Re: Re: Re: Bluetooth signal strength
if fact the design of microwave ovens take particular care to eliminate 'standing waves' as that reflected energy would re-enter the magnatron and destroy it.
(just like in the old CB radio days, were you have to "TUNE" your antenna with a VSWR meter.)
Also if that were the case the inside of your microwave over would have to be round or toroidal in shape (they are usually square).
And be of a specific size so that the internal dimentins of the over would be at some specific resonant frequency (the freq of the oven itself).
They are square and WAY to big to be at resonant cavity, (a resonant cavity for microwave oven frequest is probably around 1 or 2 cubic centremetres, inside of your micorwave over might be 9 litres.
plus the resonant frequency would change with 'load', so when you put food into the microwave you would change it frequency and go out of resonance.
A microwave over just like you cell phone uses DIRECT radiation from the source, and does not rely upon reflection (endlessly within a box).
Have you ever wondered why you DO NOT have to wait a specific period of time before you are allowed to open the door of your microwave.
if you are right, you would have to wait for the energy to 'die down' before being allowed to open the door.
(waiting endlessly could take quite some time) !!!

Re: Re: Re: Re: Re: Re: Bluetooth signal strength
you're probably right, but once you take DNA out of a cell, it is "dead" it is not dividing, it is not living and it does not have the cell around it for it to function as DNA wants to do.
So they got a whole bunch of DNA stopped them from functioning as DNA then applied RF to them and confirmed that YES,,, they are still not functioning as DNA !!

Re: Re: Re: Re: Re: Bluetooth signal strength
not have enough energy to break a chemical bond.
and we ALL know that cellphones do not operate on a single photon basis.
you only need ONE (1) single lone photon at the right place at the right time, to cause a tiny variation in the way a cell divides during the critical DNA splitting stage to cause a 'glitch' or 'spike of noise', that could affect the splitting of the DNA and create an 'error' (ie cancer).
there is also a very large group of people (myself included) that if they (we) use a cell phone for a longer period of time, we will (and do) develop headache's on the side of the head where we have the phone.
So now I always use my cell phone with earphones and extension mic, and keep the phone antenna as far away as possible.

What they do not prove is whether this CAUSES cancer. What they show without a shadow of a doubt is that the brain tissue is absorbing radiation.

Re: Re: Re: Bluetooth signal strength
"Your phone is basically a radio transmitter and receiver. When it's
turned on, it receives and transmits radio frequency (RF) signals.
When you use your phone, the system handling your call controls the
power level. This power can range from 0.006 watts to 0.2 watts in
digital mode."
Analog mode kills the battery really fast, but the last time I saw analog mode was about 10 years ago while roaming in the middle of no where.
GSM phones typically use more power for the antenna because of sensitivity to noise. CDMA is better, but more expensive.
You may also notice that microwave radiation is VERY readily absorbed by water. Guess what our body is mostly composed of? Water just turns it into heat.
At max, 0.2 watts of heat is nothing. But most of that energy isn't going to be absorbed by your body. I can absorb more heat from the sun while standing outside.
[ link to this | view in chronology ]
Re: Re: Re: Re: Bluetooth signal strength
What antenna gain value ?
(if the antenna gain is 3db, then that 0.2 watts is equavelent to 0.4 watts)
if it is a 9db gain antenna would radiate about 1 watt, (probably average) and as stated, probably 1000 times more than that value at peak.
So for very brief periods of time (the worst times) your little cell phone could be radiating 1000 watts (1KW) of RF power, with your head consuming almost 50% of the near field radiation pattern.
Just find the specs and do the math..
its a 'digital' modulation technique, that 0.2 watts would be the average based on power consumption to the transmitter stage.
the instantanious power levels could easily be 10, 100 or 1000 times larger than 0.2 watts.
which also means you get very high 'delta c' or a high 'rate of change' of power levels, that has a far more significant effect on what it interacts with than average or 'continuous' power.
if you consider your brain as a pure resistance then P=IV, ie current times voltage, but if the load contains 'reactance' (ie capacitance or inductance) then the power level dissipated in that reactive load does not relate to P=IV but is based on 'rate of change' of the signal.
A capacitor with an infinate rate of change across it will provide infinate current (ie high rate of change = high current).
An inductor with an infinate rate of change across it will provide an infinate voltage (ie high rate of change = high voltage).
The RF out of a cell phone is allready at a high rate of change (ie its a high frequency), plus the modulation techniques used (digiatl) also apply a secondary high rate of change ontop of that signal.
(that is, you start with a high frequency, then switch it on and off very quickly).
Nothing in nature is a 'pure resistance' everything contains inductance and capacatence.
So it would be virtually impossible to calculate specific voltages and currents induced by a mobile phone in human tissue based on the undefined output of a cell phone.
Especially when you only need ONE photon to strike ONE ATOM in the right spot at the right time to do the damage.
It would make it an almost impossible to predict statistical probability.
Just as going outside your house for a walk would increase your statistical probability of being run over by a car, it's impossible to predict, but you know it will and CAN happen, you know the risk exists but you decide you are willing to take that risk and play statistical lotto with your life.
I dont know if anyone else has mentions "near field" Vs "far field" but "near field" RF levels (and rate of change of power) are far higher than far field.

Re: Re: Re: Bluetooth signal strength
Digital phones, in use since ~1995, and what all of you are now using, max out at around 0.5W.
Also, the frequencies are not strictly "like a microwave oven". 2.4GHz, for example, is a resonating frequency of water. This is why ovens use it to stimulate water molecules and heat your Hot Pocket pizza. Mobile phones actually avoid all the resonating frequencies of water, because they are so readily absorbed in the real world of plants and people that they are less useful for communication.
That 2.4 band eventually got put to use by WiFi and home cordless phones. USA Cell phones, mostly, run at 1.9GHz, but also at 800MHz, 2.1GHz, 1.7GHz.
I don't see much parallel between the past "unproven harms of tobacco smoking" and the current "unproven harms of cellular phones". Phones may, indeed, cause cancer. But despite the fact that many good studies have been performed, there still is no proven or suggested connection between cancer and phones.
You are spot on about the benefit Bluetooth offers. Also, it does not need to transmit at full power if your phone is only 3 feet away. You are transmitting your voice 3 feet instead of 2 miles. Because of the inverse square propagation rules, the power required is exponentially less.

Re: Re: Do(es) Bluetooth waves cause cancer? No?
Yes, they do.
(if you made a bluetooth signal large enough and focused into a load it would act like any other form of electromagnitic radiation and cause biological effects).
But bluetooth as it stands would not cause any increase in cancer over that of the normal level of background radiation that occures naturally. (called 'the noise floor')
there has been no recored links with bluetooth and cancer.
but bluetooth is very very different to cellular phones.
bluetooth uses spread spectrum modulation techniques for a start, and far less power, the peak power at any one time or frequency from a bluetooth transmitter is probably lower than the noice floor. (than background, natural noise levels).
There is no high energy impulse spikes from bluetooth that you experience daily from cell phones. When they are seeking a cell or receiving a call for example.
we've all heard that racket that a cell makes on other things.
that is due to the very high instanious power levels and high rates of change that the phone uses.
just as you would not expect a cell phone to be able to 'cook a chook' by placing it near it, you would not expect a bluetooth to cause as much damage as a cell phone attached to your head.
you have to start to think a little more objectively here, you know a high power laser beam would cut your hand off, and a low power led would not even feel warm.
But they can both be light (non-ionizing radiation) at the same frequency.
or the difference between if I got a small bit of lead and threw it at you, it might hurt a bit (probaby not, I cant throw very hard), but if I got that same bit of lead and shot it out of a gun it would probably do alot more damage.
or if I threw a million bits of lead, (but not very hard) it would still do alot of damage. (a million times more than one).

The SUN is a much larger source of high energy photons.
I doubt I got cancer because I used a mobile phone though, but i doubt the overall average of incidents of cancer have significantly increased with the massive increase in mobile phone usage, I think there would be far stronger links to cancer from other chemicals, and modern industrial processes, and pollutants (PAH's) that would account if anything to an overall increase in the rate of certain cancers.
that couples with quicker and more effective detection methods, and a higher social awareness of cancer symptoms, will naturally result in a higher rate of cancer detections.
That is not to say that exposure to high levels of RF would not be a statistical contributing to the highter incidents of carcinomas.
(BTW: if you can possibly avoid it, dont get cancer).

Mobile phones output non-ionizing radiation. This is the type of radiation which has been found, time and time again, to not cause DNA damage, and therefore not cancer.
So, why is it that we're hearing that cell phones may have been found to be carcinogenic, but not about the fundamental new development in particle physics that non-ionizing radiation behaves differently than we thought? That's kind of a big deal.
If cell phones cause cancer, that would imply that perhaps a particularly intense shade of blue might also cause cancer. However, no such theories are being discussed in light of this news.

Re: non-ionizing radiation
so would be be happy to place your head inside a microwave oven for 10 minutes just because its "non-ionizing radiation"?
Or stand day after day, in all that non-ionizing bright sunlight until you get skin cancer ?
Do you not think there is a link between non-ionizing sunlight radiation and the incidence of skin cancer ?
So according to you, sunlight (non-ionizing radiation) does not cause cancer ?
Do you think a tanning booth produces ionizing radiation ? do you know there is a very strong link between tanning booths and skin cancer, due to the non-ionizing radiation produced.
(tanning booths do not produce ionizing radiation).

Re: Oh for chrissakes.
Go to your local metal working factory, and find their laser sheet metal cutter, and put your finger in the laser beam.
Then you can scientifically determine if that NON-ionizing radiation causes you any biological effects that may be detrimental to your health.
So, why is it that we're hearing that cell phones may have been found to be carcinogenic
because they have !
but not about the fundamental new development in particle physics that non-ionizing radiation behaves differently than we thought?
because particle physics is a branch of science that deals with IONIZING radiation. (ie high energy PARTICLES).
(thats why its called particle physics).
unless you can provide an example of where modern physics have show any such thing about the fundamentals of electromagnitic radiation then we can asses what you are talking about.
you might as well have said, "why dont we investigate this new species of fish".
If cell phones cause cancer, that would imply that perhaps a particularly intense shade of blue might also cause cancer.
Yes, exactly..or red or UV or infrared, or microwave, or low frequency, or UHF/VHF or the 6 kelvin sun light.
or the particularly intense shade of blue light from a TANNING BOOTH....
it might be that particularly intense shade of blue is one of these !!!
Long-term exposure to artificial sources of ultraviolet rays like tanning beds (or to the sun's natural rays) increases both men and women's risk of developing skin cancer. In addition, exposure to tanning salon rays increases damage caused by sunlight because ultraviolet light actually thins the skin, making it less able to heal. Women who use tanning beds more than once a month are 55 percent more likely to develop malignant melanoma, the most deadly form of skin cancer.

Re: Squre law.
sorry, but physics and math will show you are wrong, there is a thing called the "squared law" which means the intensity of the signal (light, radio, sound) decreases by the square of the distance.
Which means a 100KW transmitter 2 miles away would provide you will far less power than a 0.1watt transmitter 2 inches away.
Then there is the issue of "near" field and "far" field, near field is close to the antenna (within a wavelength or so) far field is many wavelengths from the source.
Near field RF is different from far field, as the EM waves have not 'stabilazed' along the lenth of the antenna, therefore you get much greater peaks and troughs in the EM field (E = electric field, M = Magnetic field) EM = Electromagnitic field.
as as your head is not a pure resistance but contains values of inductance and capacitance then it has it's own reactance to rate of change of E and M fields.
Why do you think when you have a mobile phone near a speaker and it rings you can hear the interference LOUDLY, but you do not get similar interfernce from the sun, or the local TV station, or anything else. (even your WiFi) does not do it.
But cell phones, MUST have high peak power levels to cause such interference to other electronics.

Evidence Of Absence
People have been looking for evidence of harm from non-ionizing electromagnetic radiation (cellphones, electricity pylons etc) for over 20 years now. There has been the occasional positive result, which has never been replicated, which is what you would expect if they were false positives. If they were true positives, then other researchers looking in the same place would find further positives, but this has never happened.
I think it has come to the point where those who claim that “more research is needed” are just in it to ride the grant-money gravy train.

There remains no reason to believe the danger.

The category boils down to: "Might possibly, maybe, within a few bars of error, have something to do with cancer", and some objects in that category might even have a negative correlation with cancer.
And even assuming it gets bumped up a few categories higher, then correlation =/= causation.

I have no issue with Mike raising this issue
there is no point in guessing, just with everything else you've mentioned coffee and so on, if it's commonly used should it not be investigated ?
and if links are found then should not those results be made available for people to asses and choose for themselves?
As the lady with the hubby with cancer stated.
"Life is the primary cause of cancer".
The only way to ensure you will not get cancer is to be not alive.
My doctor said the same thing to me, he said (about my cancer) 'there is only ONE other alternative'.
and later when I commented about the effect of the surgury, he said "it's far better than being dead".
I agree with him
(he also told me if he removed the stiches out of my neck my head would fall off, but I did not believe that one :))
Im glad im here to joke about it, but if you can help it at all, DO NOT GET CANCER... please.
if I had a worst enemy I would not wish that on them.

cell phones and cancer
There is a move for younger children to use cell phones, and that is controlled by parents - so, yes, the report will make a difference.

Shamefully inaccurate
That is a shamefully inaccurate description of the WHO report. So bad, in fact, that you really should issue a retraction.
