Much like smoking, the people that have a vested interest in equipment that uses RF have a strong influence on the information that winds its way to the user. As a primary defence contractor, we are required to have RF exposure training. The information we get is a little more honest.
Wes is totally correct on the aspect of higher frequency=higher danger. Mobile phones are much less power than a 5w CB, but the freq is a lot higher and some people tend to spend a lot more time on a phone. Those hands-free earphone thingies are better but they also radiate. Why they don't have ferrite beads I'll never know. So to answer your question: How long is a piece of string? Get the mike/earpiece thingie.

It makes them safer than a hand-held with a full size ¼ wave or a high gain, yes. It's wasted power, though. I guess this would have been on the F course but the rule of thumb is to use the least amount of power that's needed to get the job done. Also, wear a tinfoil hatslipknot wrote:but then again, they dont use high gain antennas, they are only rubber duckie antennas, does this make it safer?

Well I dunno about CB but amateurs have had their heads in close proximity to high RF fields for a long time, and we're all perfectly normal...

I really wanted to comment to this post but I don't think I can, without saying something that will offend anyone.
Some of us are normal, some others are not so normal!
But we are all here for one reason - to share a great hobby and to interact with others who share the same interests
