Of course the absence of evidence indicating that something is harmful, does not PROVE that it is not harmful.

But this study tells me a great deal. Most notably that people's well-being depends more on their imaginations than on the "radiation" from the electromagnetic transmitters. Which I would have expected from the survival and well-being of many many many (read: ALL) people who are exposed to electromagnetic radiation all the time, every day. Most of us humans in the developed world are exposed to it all the time.

And we are all exposed to sunshine too, which is probably more dangerous...

Of course - no point in trying to prove a null hypothesis. The researcher did say "Our study leads to the conclusion that short-term exposure to mobile phone mast signals is not related to levels of well-being or physical symptoms in these individuals" indicating that she is well aware of the limitations of the study so far.

Most of what I've seen on this topic so far has been anecdotal, so I was pleased to see something that had been done with scientific method, no matter how inconclusive at this point.
