the news is always quick to jump at studies that have not been reviewed or are too early in their research to be able to produce publish-worthy findings. From what I've read, yes, cell phones do emit a small amount of radiation, but no, it is not enough to effect your health or give you any type of cancer. I honestly believe the situation calls for no action, because there has been no real evidence that would justify any drastic action to reduce the already very low amount of radiation phones produce. So even your solutions like speaker phone or use of blue tooth is not necessary because there is no real risk. Because in reality, no one would use speakerphone especially if its a private call (plus I find the feature to be annoying and useless anyway) and there's also a lot of people (like me) who see no point in investing in a blue tooth. Granted this all from the perspective of a guy who doesn't talk on the cell phone much to begin with but even if I did, I wouldn't be concerned.
Crap like 'cell phones can be a health risk' is just another prime example of the general news media making something out of nothing to further plague our hypochondriac fears of bad health here in America. I mean I get it; the news is trying to spread just that, news to the people. But at the same time it becomes annoying when so much as using a phone suddenly guarantees you've got cancer. It also doesn't help when people take the news as pure fact and don't look into these issues themselves.
