I want to know if the food I eat at a Restaruant is reasonably safe and will NOT kill me with piosioning.
Just like I expect the consumer products I purchase are reasonably safe and will NOT harm me.
I'm very much a free market limited government guy, but I think that is a reasonable role for government in business, "REASONABLE" levels of consumer protection/safety and licensing. Government gets into all sort of other things it should and Government often takes it too far, OSHA and safety for example, where they write regs that you have to use a respirator with Windex to clean windows.
The studies show there is NO link between cell phones and health problems, BUT there is antecdotal evidence that some people have suffered some side effects from cell phones and a few serious ones, including people that develop a brain tumor exactly where the attenna of the phone they used for years positioned next to their head (very, very rare). Because of that most people agree, studies need to continue and eduacation of the consumer about the risks/situation should continue as well.
Keep in mind, a cell phone is a fairly powerful transmitter, its level of radiation is fairly low, but its probably the biggest source of radiation most of use experience.
Length of exposure is a much bigger factor than quantity of the exposure in most cases. i.e. most people will NOT be effected by a much higher radiation does than a cell phone for a short period and then never see that much again, would suffer no bad health effects, but someone exposed to a small dose very often for years, would be far more likely to develop side effects.
Using the bluetooth devices or plug in headset where you place the phone on the table or use it while its NOT on your body, are considered to reduce your risk greatly. Yes, bluetooth is just another transmitter, but it transmitts at a much much lower power than your cell phone, that why it only has the ability to stay linked over 10 feet. While Cells stay linked up to 3 miles. Remember, the level of radiation drops expodentially with distance, just a difference of a few feet between you and your cell phone while you use it can drop the radiation level signficantly.
As well, just try NOT to use your cell phone all the time. Someone that uses it a few minutes a day is far less likely than someone that uses it more than an hour a day.
