The thing is, you can't do serious research. The information is not out there. AFAIK the scientific world is divided on the issue and of course phone compeanies don't really want research done. Also, it'd probably take long-term (30 year+) research on a huge sample to get any meaningful data.
Currently, you can look up different reports that say one of 3 things. 1)No need to worry, it's as safe as it gets. 2)There is serious cause for concern. Some stats show that eg. cancer rates have shot up around antennae etc. But we don't have solid data. 3) It will kill you before Christmas.
