[citation][nom]flamethrower205[/nom]What's so bad about SF's response to be a bit more conservative wrt cell phone radiation? Even if there is no conclusive evidence that it causes damage, that doesn't rule out the possibility that it does. To all the people who get pissy about the masses being concerned about the radiation, is there conclusive evidence that the radiation DOES NOT cause problems? We live in a society in which new technology is always coming out, often much faster than we can really understand it in full. Conclusive evidence for cell phone studies may come out in decades, who knows. But in the interim, why is it so bad to use history as a lesson? Xrays were a fad when they came out, and later people realized that they are in fact harmful. Tons of older high school science books suggest allowing kids to play with mercury...and then people realized this was harmful. The list goes on and on. Our history is full of harmful new technologies and people swearing that it's safe until years later conclusive evidence comes out showing it's not.From this point of view - and until conclusive evidence comes out - fears are justified. Hopefully cell phones are proven to be ok, but until then, I'm not going to keep mine right next to my balls all day.Finally, what do you define as "conclusive"? That's a matter of statistical opinion, which always has a margin of error. The fact that there is some evidence, one way or another, is still worth something, just not as much as if it were very confident.[/citation]
Because anyone who's taken even 1 class of quantum chem or physics knows that microwaves are harmless and there's an absolute mountain of data that says exactly that and not one cell phone study that says "your phone will kill you" (well unless you text and drive perhaps). The problem is perception, when you say radiation, people immediately think it ties to radioactivity or UV or xray radiation and assume all radiation is bad. That simply isn't the case. Radiation just means something is radiating, it doesn't necessarily mean "invisible waves of certain doom".
Case in point, the highest MW radiation is about 2x10^-23 J/photon (and thats 300 GHz not the 1-5 handheld devices use). On the other hand, the average human body radiates IR at approximately 10,000 nm or 2x10^-20 J/photon, meaning your body puts out radiation thats 1000x as powerful as your cell phone and it's doing it ALL THE TIME. Your monitor, tv and cellphone display put out light radiation, which is approximately 26,000x as energetic as cell phone radiation; yet despite hours of watching crappy reality TV while sitting in lighted rooms, people aren't keeling over from light induced cancer.
Now if you actually wanna talk about harmful radiation, UV puts out photons that are actually 1 million times as powerful as MW and xrays put out photons 1 billion times more energetic than MW (yeah Carl Sagan B as in billions). UV and Xrays are harmful because those photons possess enough power to knock electrons off pretty much any molecule or atom, hence why they're called 'ionizing'. Ionizing radiation possesses enough power to tear apart DNA and increase your risk for cancer. If radiation isn't ionizing it, can't do this and won't give you cancer.
So, I can already hear the 'but Maes, the cellphone radiation is concentrated near your head and that'll cause harm because you're absorbing a concentrated dose'. Again, people are confusing this with high energy radioactivity and/or ionizing radiation. Exposure to high energy radiation/radioactivity in a concentrated area can be bad and can cause cancer because you may overwhelm your body's natural healing ability to repair gradual radiation/radioactivity induced damage that you're always absorbing from solar/space/earthbound radioactivity/ionizing radiation sources. Of course, long term/low-level exposure is bad too, but generally not as much of a problem because your body can heal a limited amount of damage and destroy cells it can't heal.
However, the key word to the above paragraph is HIGH ENERGY and IONIZING, if radiation isn't ionizing, it will not ionize your DNA and rip it apart. Even more radiation of the same energy level, even if it's super concentrated, will not induce ionization. That's really the whole basis behind quantum physics and chemistry, if a single photon doesn't possess enough energy to ionize a molecule, more photons of that same energy content will NEVER ionize that molecule.
And if you don't believe me, well, there was this guy in the early 1900s that discovered exactly this phenomena, called the photo-electric effect, they gave him the Nobel prize for it, went by the name of Einstein. He basically discovered that certain metals will ionize when exposed to radiation that met a certain level of energy content (dubbed quanta). He found out that if you crossed this minimum threshold of energy/photon the metal would shoot off electrons at a certain speed, increasing the intensity of light (the number of photons) increased the number of electrons and increasing the energy content of the light (via smaller wavelengths) made the electrons go faster (or made them higher energy). If you failed to meet this minimum energy/photon requirement you wouldn't see a single electron, no matter how intense you made that light.
TL;DR version: MW radiation doesn't possess the power to harm your DNA, no matter how concentrated you make it because Einstein says so.
