          In field tests in Germany, Clothianidin was found to be EXTEREMELY LETHAL to bees because they bring the tainted pollen back to the hive, and it is fatal in very low doses. Literally one bee carrying the insecticide back will kill hundreds of bees in the colony.

            Admittedly, I only skimmed it and did read that the results seemed to conclude that cell phones were not a cause. However, I was trying to explain someone else's post -- probably a futile cause. The word "speculated" in my post for a reason.

            Perhaps I should have emphasized that other people have speculated and there's no real studies that prove or disprove it (I won't count a single study as disproving, for all I know the methodology was flawed.)

          • Placing phone inside a hive is too many variables. They should try the experiment with just an antenna in the hive. The phone itself will have electronic hum, plastic outgassing, and that Nokia ring tone itself will cause many insects to flee.

            • All of these issues may cause a false positive but not a false negative. In this case there was no correlation between cell phones and CCD.

      • Thanks for the response. I have searched a bit but there are some variables I have not seen quantified in comparison studies. For example, some towers have more or less antenna and/or more power as well as the fact your phone is 2 inches from your head when on a call. The tower is on 100% of the time. Is the differences in exposure over time due to distance so great that these don't factor in at any significant amount?

      Non-ionizing radiation shouldn't directly cause cancer by the inducement of DNA damage. However, non-ionizing radiation could conceivably cause inflammation due to localized increase in heat. Increased inflammation can increase the risk of cancer. [That's basically why asbestos causes cancer, even though asbestos itself is spectacularly inert.]

          External temperatures don't influence internal temperatures much, so long as humans can maintain homeostasis. That said, I would expect (after controlling for skin pigmentation) to find more skin cancers in warmer areas... but that's not what you're asking about.

I agree with intensity being the issue but the intensity of sun light per area will much higher than the intensity of RF per area. Put a one cm2 sample in sunlight in the summer and check the heat gain vs exposing the same size sample to a milliwatt em source of your choosing.

              No, but it's fairly good when we're talking about internal body temperatures... and when it does fail and your temperature goes much beyond 42C, you die.

                That was kind of my point. the total power emitted by a cell is very small and it is not focused. Now as to should they test that is up for debate. If they know what the max output of cellphones are and know the absorption rates of tissues and the required heat to cause an issue then it becomes a math problem. I would bet that they have already done this. These tests are necessary because people refuse to believe the math.

        Except that increased heat by itself does not cause inflammation. Rather - it is the reverse. Namely, inflammation causes increase in heat (through a variety of different mechanisms including cytokines, changes in vascular permeability, etc...). True, if you get heat high enough then you can destroy cells which in turn will induce an inflammatory response to clean things up. But those temperatures req

      Your stated logic really does not make since, given a portion of the UV spectrum is non-ionizing yet still has been shown to indirectly contribute to DNA defects, elevating cancer risk. Furthermore, you can't really just postulate that all lower frequency EM radiation is safe given that given that lower-wavelengths of EM do interact with your body. Microwaves and infrared are lower frequency than visible light, but still can instantaneously burn you and long term microwave exposure can cause cataracts.

  • Let's not forget that there are two types of conjectures: those that have been proven false, and those that have not yet been proven false, according to Karl Popper. So the conjecture "Cell phone's don't cause cancer" can be disproven by just one case where cancer is caused by a cell phone. Add that to the EXTREME difficulty in attributing the cause of cancer, and we'll never be completely sure.

    So stop worrying about all the things that contribute so little to the risk that a 350,000 person study can't identify a link. Enjoy your life, and avoid the things with a strong correlation to cancer, like tobacco, excessive UV exposure, high levels of radioactivity, etc.

    We don't need more study of a link between cell phone usage and cancer, because repeated studies have shown that any risk is too low to measure even in large studies of long term users, therefore, too low to worry about.

    • The supposed cancer risk with cell phones is that a microwave radiation source close to your skin will increase the temperature in some cells which increases the cancer risk. However, this temperature increase is very localized and only temporary. If there is a risk, it will be way below 10^ -5 and hard to quantify, since it is somehow a problem to find people that don't expose themselves to other cancer risks, like walking in the sun, eating a byte of junk food, or not getting enough sleep or being stresse

      • The microwave frequency that heats water is 2.45GHz, and no cell phones operate at that frequency, so the effect will be minimal. Also, the transmit power of cell phones it 0.6W or less (usually much less except when you're at the fringe of reception). The power and frequencies are so small that they will probably never be able to establish a correlation, even if there is some small risk. The studies that have been done are sufficient to eliminate it as a real concern, even though we'll never be able to pro

        • The microwave frequency that heats water is 2.45GHz,

          No, it's not. That frequency is used for microwave ovens because it is the Industrial, Scientific and Medical (ISM) band, and hence you don't need a FCC license every time you turn your microwave on.

          Water heating isn't terribly sensitive about what frequency. It's not a resonance-- it would heat equally well at 2.25 or 2.55 GHz. The oscillating electric field adds energy to the water molecule dipoles.

          • Thanks for that correction. I had missed that.

            Still, the power levels are so low, maximum is 1% of a modern microwave oven, and radiated in all directions so that amount actually reaching human tissue doesn't produce enough heat to even feel it, certainly not enough that blood circulation can't remove any excess heat. Therefore, damage from heating is extremely unlikely. And since it's non-ionizing, there is no other known mechanism by which it can cause harm (cancer or other).

    To me, one of the biggest pitfalls of the "cell phones cause cancer" idea is that brain cancer is the primary kind being suggested. Why? The skin, bone marrow, and gonads (for those who keep phones on their belt or in their pocket) are all significantly more sensitive to radiation-induced cancer than the brain. And when you talk on the phone, any signal has to go through skin and bone before it gets to the brain. If cell phones could indeed cause cancer, we should see much stronger positive correlations in
