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.
