Is Health Canada failing us re: cellphones radiation safety?

I ask becase I honestly don't know. I know that past studies have not shown any obvious danger, but have things changed? Is this a real concern or just fearmongering?

Anyone out there able to comment?

Recently 53 researchers and specialists in the field of wireless radiation wrote to the health minister, stressing that Canada’s current guidelines, Safety Code 6, are “obsolete.” They highlight that Health Canada has minimized or disregarded studies on cancer, DNA damage and other adverse health effects, at exposure levels below current limits. Furthermore, 43 Canadian medical doctors are asking Health Canada for resources to deal with the ever-increasing number of patients who report becoming ill from exposure to wireless radiation.
